Next, with reference to Fig.3-16 explains the process of obtaining information traffic, which is executed by the CPU 41 included in the navigation device 2, and the process of allocation information of the traffic that is executed by the CPU 11 provided in the center of the 3 distribution of information to distribute traffic navigation device 2, the navigation system 1 configured as described above.

Figure 3 shows the main block diagram illustrating the process of obtaining information traffic, which is executed by the CPU 41 included in the navigation device 2, and the process of allocation information of the traffic that is executed by the CPU 11 provided in the center of the 3 distribution of information to distribute traffic navigation device 2. Figure 4 shows a block diagram that illustrates the process for the installation destination of the road, shown in figure 3. Figure 5 shows the BL is a K-scheme, which illustrates the subprocess to process the range of the distribution, shown in figure 3.

First, with reference to figure 3 will be explained the process of obtaining information traffic”, which is executed by the CPU 41 included in the navigation device 2. The program shows the stages Sl1-S13 in the flowchart in figure 3, stored in the RAM 42 or the ROM 43, included in the navigation device 2, and is executed by the CPU 41.

As shown in figure 3, first, at step (hereinafter expressed simply as "S") 11, the CPU 41 performs the decision-making process, it was determined whether the destination through the input operation performed on the operating unit 24, such as a touch screen or switch operation. If the destination has not been determined (S11: NO), the CPU 41 terminates the process. On the contrary, in the case of a decision that the destination has been entered (S1l: YES), the CPU 41 temporarily stores the coordinates of the destination, or the like in the RAM 42, and then proceeds to the process at step S12.

Then at step S12, the CPU 41 transmits to the center 3 distribution information query command to query information traffic, as well as ID that identifies the Navigator, the coordinate data of the current location TRANS is Ortego means, which is the main CPU 41 (hereinafter simply referred to as "vehicle position"), the coordinate data of the destination, the search criteria route information version information 37A navigation maps, etc. then at step S13, the CPU 41 receives from the center 3 distribution information current information 16A traffic, etc. that includes information load and information management traffic and stores the received current information 16A traffic, etc. in the current information 36A traffic, etc. before to finish this process.

Next, with reference to figure 3 will be explained the process of information dissemination traffic"performed by the CPU 11 provided in the center 3 the distribution of information. The program shown in the steps S111-S120 in the flowchart in figure 3, stored in the RAM 12 or the ROM 13, included in the center 3 distribution of information, and is executed by the CPU 11.

First, at step S111, the CPU 11 receives the query command to query the information of the traffic that has been transmitted from the navigation device 2 in step S12, as explained above, as well as ID that identifies the Navigator, the coordinate location data transport is the means, the coordinate data of the destination, the search criteria route information version information 37A navigation maps, etc. the CPU 11 then stores the received information in the RAM 12. The CPU 11 searches the base of the route to reach the destination according to the received search criterion based on the information 14A card for the purpose of update, which is version information 37A navigation maps stored in the database 14 of the information card on the side of the center, and stores the basic route found by the search, in the RAM 12.

At step S112 (the CPU 11 reads the base range of the distribution, which is used to transfer information 16A, 16B and 16C traffic from the database 18 range, distribution, and saves a few basic range of distribution in the RAM 12. For example, in the case where the distance from the vehicle location to the destination is equal to or more than 100 kilometers, a range having an area of 50 square kilometers, in which the location of the vehicle is at its center, or a range having an area of 30 square kilometers, is positioned in the forward direction from the location of the vehicle is read from the DB 18 range distribution and stored in the RAM 12 as the base band is and distributions.

Then, in step S113, the CPU 11 executes a subprocess of the process of installation of the target road"to set the road category that serves the purpose of allocation information of the traffic.

In the next section with reference to figure 4 will be explained subprocess of the process of installation of the target road. As shown in figure 4, at step S211, based on the obtained location data of the vehicle, the CPU 11 determines whether the vehicle in which the navigation device 2, on one of what is called Expressway and a toll road such as a national highway, urban Expressway, the road only vehicles or public toll road, using the information 14A card for the purpose of update.

If it was determined that the vehicle in which the navigation device 2, is one of what is called Expressway and toll road (S211: YES), the CPU 11 proceeds to the process at step S212. At step S212, the CPU 11 sets the category of the road that serves the purpose of allocation information of the traffic, one of the expressways and toll roads, and all roads which, which include small streets and any more major roads and are located in the surrounding area of the output of the above-mentioned high-speed highways or toll roads. The CPU 11 then stores the category of the road, which was installed in the RAM 12.

Additionally, the CPU 11 sets the changed distribution band, which is the range of the distribution, serving as a target allocation information of the traffic instead of the base range of the distribution, which was set at step S112 (the route mentioned by Expressway or toll road, which is included in the basic route found by the search in step S111, and surrounding the exit area of the above-mentioned high-speed highways or toll roads. The CPU 11 then stores the modified range of the distribution, which was set in the RAM 12. Next, the CPU 11 reads the flag of the modified range of the distribution of the RAM 12 and assigns "1" is read, the flag of the modified range of the distribution, before re-save the modified flag of the distribution band in the RAM 12. After that, the CPU 11 returns to the main flowchart. It should be noted that when the CPU 11 is activated, "0" is assigned to the flag of tennage range distribution and stored in the RAM 12.

On the contrary, if it is determined that the vehicle in which the navigation device 2, is not one of what is called Expressway and toll road (S211: NO), the CPU 11 proceeds to the process at step S213. At step S213, the CPU 11 sets the category of the road that serves the purpose of information dissemination traffic, all roads, including small streets and any larger roads, and stores the category of the road, which was installed in the RAM 12. After that, the CPU 11 proceeds to the process at step S214.

Examples of distribution ranges, each of which serves the purpose of information dissemination traffic, are explained with reference to figa and 6B, in accordance with the cases, when the vehicle in which the navigation device 2, is (S211: YES), and is not (S211: NO) in one of what is called Expressway and toll road.

Figa shows an example of the range of the distribution, which serves the purpose of information dissemination traffic in accordance with the case when the vehicle in which the navigation device 2, is one of what is called Expressway and toll roads is th (S211: YES). Figv shows another example of the range of the distribution, which serves the purpose of information dissemination traffic in accordance with the case when the vehicle in which the navigation device 2, is not one of what is called Expressway and toll road (S211: NO).

As shown in figa, in the case when the label 51 location of a vehicle, which indicates the vehicle 2, which is installed on the navigation device 2, placed on highway 61 (S211: YES), the CPU 11 sets the category of the road that serves the purpose of information dissemination traffic, highway 61, on which is positioned the label 51 location of a vehicle, as well as all roads, which include small streets and any more major roads and are located in the surrounding area of the outlet 62 from highway 61, which is the route search. The CPU 11 then stores the category of the road, which was installed in the RAM 12. In addition, the CPU 11 sets the changed distribution band, which is the range of distribution serving as the target distribution information of the movement of the Tr is Sparta instead of the base range of the distribution, which was set at step S112 (, a route from the route search, positioned on highway 61 in the forward direction from the mark 51 location of a vehicle, and an area of 10 square kilometers, in which the output 62 from highway 61, located on the route search is at its center. The CPU 11 then stores the modified range of the distribution, which was set in the RAM 12.

As another example, as shown in figv, in the case when the label 51 location of a vehicle, which indicates the vehicle in which the navigation device 2, is positioned on the common road 65, such as a national road or a prefectural road other than an Expressway or toll road (S211: NO), the CPU 11 sets the category of the road that serves the purpose of allocation information of the traffic, all the roads, which include small streets and any larger roads and which are within the basic range 66 distribution with an area of 30 square kilometers and is located on the route search in the forward direction from the mark 51 location of a vehicle. The CPU 11 then stores the category of the road, which would be the as installed, in the RAM 12.

Then, as shown in figure 4, at step S214, the CPU 11 calculates the distance from the vehicle location to the destination and the movement needed to pass the base of the route, based on data associated with the location of the vehicle and the coordinate data of the destination that have been received. The CPU 11 then stores the distance and the time required movements, which were calculated in the RAM 12.

At step S215, the CPU 11 performs the process of making decisions in order to determine whether at least one of the distance and time of movement from the vehicle location to the destination large (for example, equal to or greater than 100 km/is equal to or longer than 2 hours). If at least one of the distance and time of movement from the vehicle location to the destination is large (S215: YES), the CPU 11 proceeds to the process at step S216. At step S216, the CPU 11 sets the category of the road that serves the purpose of allocation information of the traffic, the roads are of a high standard, including national expressways, urban expressways, road only automobiles, the lei, conventional toll roads and national routes identified by one and two digit numbers. The CPU 11 then stores the category of the road, which was installed in the RAM 12 and returns to the main flowchart.

On the contrary, if the distance from the vehicle location to the destination is small, and the desired motion is also small (S215: NO), the CPU 11 proceeds to the process at step S217. At step S217, the CPU 11 performs the decision-making process to determine whether at least one of the distance and time of movement from the vehicle location to the destination, the average value (for example, equal to or greater than 30 kilometers, and shorter than 100 km/is equal to or longer than 45 minutes and shorter than 2 hours).

If at least one of the distance and time of movement from the vehicle location to the destination has an average value (S217: YES), the CPU 11 proceeds to the process at step S218. At step S218, the CPU 11 sets the category of the road that serves the purpose of information dissemination traffic, prefectural roads and major roads. The CPU 11 then stores the category of the road, the cat heaven was established, in the RAM 12 and returns to the main flowchart.

On the contrary, if the distance from the vehicle location to the destination is not of medium length, and the desired motion is also not average duration (S217: NO), the CPU 11 decides that at least one of the distance and time of movement from the vehicle location to the destination has a small value (for example, shorter than 30 km/shorter than 45 minutes), and then proceeds to the process at step S219. At step S219, the CPU 11 re-establish, as the road category that serves the purpose of information dissemination traffic, all roads, including small streets and any more major roads. The CPU 11 then stores the category of the road, which was installed in the RAM 12 and proceeds to the main block diagram.

Next, examples in which the road category that serves the purpose of information dissemination traffic, installed according to one of the distance and time of movement from the vehicle location to the destination, will be explained with reference to figa, 7B and 7C. Figa shows an example in which the road category that serves the purpose of information dissemination traffic, set in place the AI with the case, where at least one of the distance and time of movement from the vehicle location to the destination is large. Figv shows an example in which the road category that serves the purpose of information dissemination traffic, installed in accordance with the case where at least one of the distance and time of movement from the vehicle location to the destination is average. Figs shows an example in which the road category that serves the purpose of allocation information of the traffic are set in accordance with a case where at least one of the distance and time of movement from the vehicle location to the destination is not enough.

As shown in figa, in the case where at least one of the distance and time of movement from the vehicle location, marked with 51 vehicle location to the destination location 67, is large (for example, equal to or more than 100 km/is equal to or longer than 2 hours), the CPU 11 sets the category of the road that serves the purpose of information distribution and transport, national road 68 and 69, as well as urban highway 70. In addition, the penny is the real CPU 11 sets the base range of the distribution 71, with an area of 30 square kilometers, the route search in the forward direction from the mark 51 location of a vehicle.

As shown in figv, in the case where at least one of the distance and time of movement from the vehicle location, marked with 51 vehicle location to the destination 73 has an average value (for example, equal to or greater than 30 miles and less than 100 km/is equal to or longer than 45 minutes and shorter than 2 hours), the CPU 11 sets the category of the road that serves the purpose of information distribution and transport, national road 74 and 75, as well as national highway 76 and prefectural road 77. In addition, the CPU 11 sets the base range of the distribution 71, having an area of 30 square kilometers, the route search in the forward direction from the mark 51 location of a vehicle.

As shown in figs, in the case where at least one of the distance and time of movement from the vehicle location, marked with 51 vehicle location to the destination 79 low (e.g. less than 30 km/shorter than 45 minutes), the CPU 11 sets the quality is TBE category of the road, which serves the purpose of information dissemination traffic, all roads, including national highways 80 and 81, urban Expressway 82, prefectural road 83, urban roads 85 and road 86 locality. In addition, the CPU 11 sets the base range of the distribution 71, having an area of 30 square kilometers, the route search in the forward direction from the mark 51 location of a vehicle.

Then, as shown in figure 3, at step S114, the CPU 11 performs the process of making decisions based on the situations of the roads within the basic range of the distribution, which was set at step S112 (whether the base range of the distribution of some range distribution, which does not contain roads, in other words, does it include the basic range of distribution of any range distribution, which does not contain links. In the case when the underlying distribution band does not include the range of the distribution, which does not contain ties (S114: NO), the CPU 11 proceeds to the process at step S116.

On the contrary, in the case when the underlying distribution band includes one or more distribution ranges that do not contain links (S114: YES), the CPU 11 proceeds to the process at step S115. On the stage S115, the CPU 11 sets the changed distribution band, changing the base range of the distribution to one or more distribution ranges within the basic range of distribution that do not contain links were excluded. The CPU 11 then stores the new range of distribution in the RAM 12. For example, the CPU 11 sets the changed distribution band, changing the angle distribution of the base range of the distribution to one or more distribution ranges that do not contain links were removed before saving the new range of distribution in the RAM 12.

As another example, the CPU 11 sets the changed distribution band, reducing the width of the base range of the distribution in the left and right direction or in the forward and reverse direction so that one or more distribution ranges that do not contain links were removed before saving the new range of distribution in the RAM 12. As another example, the CPU 11 sets the changed distribution band by dividing the base range of the distribution of sections in the left and right directions so that one or more distribution ranges that do not contain links were removed before saving the modified range of the distribution is tion in the RAM 12. In addition, the CPU 11 reads the flag of the modified range of the distribution of the RAM 12 and assigns "1" is read, the flag of the modified range of the distribution, before re-save the modified flag of the distribution band in the RAM 12. After that, the CPU 11 proceeds to the process at step S116.

Next, examples in which the modified range of the distribution is set by modifying the underlying range of distribution to one or more distribution ranges that do not contain links were excluded, will be explained with reference to figa, 8B and 8C. Figa shows an example in which the modified range of the distribution is set by reducing the width of the base range of the distribution in the left and right directions so that were excluded distribution ranges that do not contain links. Figv shows another example in which the modified range of the distribution is set by changing the direction distribution of the underlying distribution band so that was excluded range distribution, which does not contain links. Figs shows another example in which a changed distribution ranges established by dividing the base range of the distribution of sections in the left and right directions so that was excluded range distribution, which is n which contains links.

As shown in figa, when the location of the vehicle is on the road in a mountainous area, the CPU 11 sets the changed range 89 distribution, reducing the width of the base range 88 distribution in the left and right directions so that such part of the basic range 88 distribution, positioned in the forward direction from the mark 51 location of a vehicle, which are superimposed on the mountain were excluded, in other words, to have been excluded those parts that do not contain links. The CPU 11 then stores the modified range 89 distribution in the RAM 12.

As another example, as shown in figv, when the location of the vehicle is on the road to the coast, the CPU 11 sets the changed range 92 distribution, which contains the Bank as the target distribution, changing the direction of distribution of a basic range 91 distribution in the direction of the coastal region to a predetermined angle so that a portion of the base range 91 distribution, positioned in the forward direction from the mark 51 location of a vehicle that collides with the sea, was excluded, in other words, so that the part which does not contain links, was and is clucene. The CPU 11 then stores the modified range 92 distribution in the RAM 12.

As another example, as shown in figs, in the case where the vehicle position is located on the lake front of lake, the CPU 11 sets the changed bands 95 and 96 of the distribution that have land as the target distribution, by dividing the basic range 94 distribution to areas in the left and right direction so that part of the basic range 94 distribution, positioned in the forward direction from the mark 51 location of a vehicle, which is superimposed on the lake, was excluded, in other words, so that the part which does not contain links, was excluded. The CPU 11 then stores the changed bands 95 and 96 distribution in the RAM 12.

Then, as shown in figure 3, at step S116, the CPU 11 performs the decision-making process to make decisions based on the situations of the roads within the basic range of the distribution, which was set at step S112 (whether there is a road that leads from the region surrounding the location of the vehicle (for example, the region of 2-6 square kilometers, in which the location of the vehicle is centered in the middle), to the road within the basic range is raspredeleniya, in other words, does the area surrounding the location of the vehicle (for example, the region of 2-6 square kilometers, in which the location of the vehicle is centered in the middle), as much or more links, which may movement than the specified number (e.g., 3-5). If the area surrounding the location of the vehicle, contains fewer links, which may movement than the specified number (S116: NO), the CPU 11 proceeds to the process at step S118.

On the contrary, if the area surrounding the location of the vehicle, contains as much or more links, which may movement than the specified number (S116: YES), the CPU 11 proceeds to the process at step S117. At step S117, the CPU 11 sets the changed distribution band, changing the base range of the distribution so that the area surrounding the location of the vehicle, is included in the new range of distribution. The CPU 11 then stores the new range of distribution in the RAM 12. As an example, the CPU 11 sets the changed distribution band, adding the area surrounding the location of the vehicle, to the base range of the distribution. As another at the EPA, the CPU 11 sets the changed distribution band, moving the base range of the distribution so that the area surrounding the location of the vehicle was included in the new range of distribution.

In addition, the CPU 11 reads the change flag of the range distribution from the RAM 12 and assigns "1" is read, the flag of the modified range of the distribution, before you can save the modified flag of the distribution band again in the RAM 12. After that, the CPU 11 proceeds to the process at step S118.

Next, examples in which the modified range of the distribution is set by modifying the underlying distribution band so that the area surrounding the location of the vehicle was included in the new range of distribution, will be explained with reference to figures 9 and 10. Fig.9 shows an example in which the modified range of the distribution is set by adding the area surrounding the location of the vehicle, to the base range of the distribution. Figure 10 shows an example in which the modified range of the distribution is set by moving the base range of the distribution so that the area surrounding the location of the vehicle was included in the new range of distribution.

In ka is este example, as shown in Fig.9, the CPU 11 sets the changed range 98 distribution, adding range distribution, with an area of about 2-6 square kilometers, in which the location of the vehicle is at its center, to the base range 97 distribution, which is positioned in the forward direction from the mark 51 location of a vehicle. The CPU 11 thus increases the range of the distribution to include the area surrounding the location of the vehicle.

As another example, as shown in figure 10, the CPU 11 sets the changed range 99 distribution by moving the base range 97 distribution, positioned in the forward direction from the mark 51 of the vehicle location to the location of the vehicle for a few kilometers (e.g., about 2-6 km). Thereby, the CPU 11 increases the range of distribution in the region surrounding the location of the vehicle.

Then, as shown in figure 3, at step S118, the CPU 11 executes a subprocess of the process of change of the range of distribution"to set the new range of distribution by changing the base range of the distribution, the basis is as on the situations of the roads within the basic range, distribution, in other words, based on, for example, on the amount of information traffic, which corresponds to the situations of the roads.

Next subprocess of the process of change the range of the distribution will be explained with reference to figure 5. As shown in figure 5, at step S311, the CPU 11 calculates the proportion of loaded links to all the links, which serve the purpose of distribution within the base range of the distribution, based on current information 16A traffic and statistical information 16V traffic, which correspond to the situations of the roads within the basic range of the distribution. The CPU 11 then performs the decision-making process to decide whether the proportion uploaded links preset value (for example, 50%).

If the proportion of loaded links is equal to or lower than a given value (for example, 50%) (S311: NO), the CPU 11 proceeds to the process at step S313.

On the contrary, when the proportion uploaded links exceeds a preset value (for example, 50%) (S311: YES), the CPU 11 proceeds to the process at step S312. At step S312, the CPU 11 sets the changed distribution band, reducing the base range of the distribution in the direction of the inside, because the amount of transmission information is the traffic, which matches the reference range of the distribution is large. The CPU 11 then stores the new range of distribution in the RAM 12. As an example, the CPU 11 sets the changed distribution band, reducing the base range of the distribution in the direction of inside when the location of the vehicle is at its center, and stores the new range of distribution in the RAM 12. As another example, the CPU 11 sets the changed distribution band, reducing the base range of the distribution towards the inside so that the vehicle location and the reference location, which serves as a support for directions to the destination, were included in the new range of distribution, and stores the new range of distribution in the RAM 12.

In addition, the CPU 11 reads the flag of the modified range of the distribution of the RAM 12 and assigns "1" is read, the flag of the modified range of the distribution, before re-save the modified flag of the distribution band in the RAM 12. After that, the CPU 11 proceeds to the process at step S313.

Next will be described examples in which the modified range of the distribution is set by reducing the base range of the distribution, sssylkami on figa and 11B. Figa shows an example in which the modified range of the distribution is set by reducing the base range of the distribution, while the location of the vehicle in its center. Figv shows an example in which the modified range of the distribution is set by reducing the base range of the distribution so that the vehicle location and the reference location, which serves as a support for directions to the destination, were included in the modified range of the distribution.

In the example shown in figa, the CPU 11 sets the changed distribution band 102, reducing base range 101 distribution that has an area of 50 square kilometers, in which the label 51 vehicle location indicating the location of the vehicle, is at its center, to the area of 30 square kilometers, in which the label 51 location of the vehicle is at its center. The CPU 11 then stores the modified distribution band 102 in the RAM 12. In another example, shown in figv, the CPU 11 sets the changed range 106 distribution, reducing the base range of 105 distribution, which includes the label 51 location of a vehicle, indicating places the position of the vehicle, and the reference location 104, which serves as a support for directions to the destination, towards the inside along the route, so the label 51 vehicle location and the reference location 104 included in the new range of 106 distribution. Then, the CPU 11 stores the new range of distribution in the RAM 12.

Then, as shown in figure 5, at step S313, the CPU 11 performs the decision-making process to decide, whether the proportion of loaded links, computed in step S311, or lower than the preset value (e.g. 10%). If the proportion uploaded links exceeds a preset value (for example, 10%) (S313: NO), the CPU 11 proceeds to the process at step S315.

On the contrary, if the proportion of loaded links to all the links within the base range of the distribution is equal to or lower than the preset value (for example, 10%) (S313: YES), the CPU 11 proceeds to the process at step S314. At step S314, the CPU 11 sets the changed distribution band, increasing the base range of the distribution in an outward direction, because there is a reserve in the amount of transmission traffic, which corresponds to the main range of the distribution. The CPU 11 then continue to the t new range of distribution in the RAM 12.

As an example, the CPU 11 sets the changed distribution band, increasing the base range of the distribution in an outward direction, when the vehicle location is in the center, and stores the new range of distribution in the RAM 12. As another example, the CPU 11 sets the changed distribution band, increasing the base range of the distribution in an outward direction so that the vehicle location and the reference location, which serves as a support for directions to the destination, were included in the new range of distribution, and stores the new range of distribution in the RAM 12.

In addition, the CPU 11 reads the flag of the modified range of the distribution of the RAM 12 and assigns "1" is read, the flag of the modified range of the distribution, before re-save the modified flag of the distribution band in the RAM 12. After that, the CPU 11 proceeds to the process at step S315.

Next will be described examples in which the modified range of the distribution is set by increasing the base range of the distribution, with links to figa and 12B. Figa shows an example in which the modified range of the distribution is set by increasing the basic di is the range of the distribution, while the location of the vehicle in its center. Figv shows an example in which the modified range of the distribution is set by increasing the base range of the distribution so that the vehicle location and the reference location, which serves as a support for directions to the destination, were included in the modified range of the distribution.

In the example shown in figa, the CPU 11 sets the changed distribution band 108, increasing the base range 101 distribution that has an area of 50 square kilometers, in which the label 51 vehicle location indicating the location of the vehicle, is at its center, to the area of 80 square kilometers, in which the label 51 location of the vehicle is at its center. The CPU 11 then stores the modified range distribution 108 into the RAM 12. In another example, shown in figv, the CPU 11 sets the changed range 109 distribution, increasing the base range of 105 distribution, which includes the label 51 location of a vehicle indicating the vehicle location and the reference location 104, which serves as a support for directions to the destination, while externally the m direction along the route, so mark 51 of the vehicle location and the reference location 104 included in the new range of 109 distribution. Then, the CPU 11 stores the new range of distribution in the RAM 12.

Then, as shown in figure 5, at step S315, the CPU 11 reads the time data, etc. from the timer 19 and receives the current date and current time. Thus, the CPU 11 identifies the factors associated with day of the week and time of day corresponding to the current time, and stores the identified factors in the RAM 12. After that, the CPU 11 performs the decision-making process to make decisions based on information 16A, 16B traffic, etc. whether the period of time that corresponds to the current time, the time period during which the roads within the basic range of the distribution, which was set at step S112 (will probably be loaded.

If it is determined that the period of time that corresponds to the current point in time, is not a period of time during which the roads within the basic range of distribution will probably be loaded (S315: NO), the CPU 11 proceeds to the process at step S317.

On the contrary, if it is determined that the time period for the store with the current time, is the period of time during which the roads within the basic range of distribution will probably be loaded (S315: YES), the CPU 11 proceeds to the process at the stage of SS316. For example, if the period of time that corresponds to the current point in time is a period of time daily commuting from suburb to city and back again) in the morning or in the evening, the CPU 11 decides that the current time is within the period of time during which the roads within the basic range of distribution will probably be loaded and proceeds to the process at the stage of SS316. On stage, SS316, the CPU 11 performs the process of step S312, because the volume of transmission traffic, which corresponds to the main range of distribution is large, and proceeds to the process at step S317.

Then, in step S317, the CPU 11 performs the decision-making process to make decisions based on information 16A, 16B traffic, etc. whether the period of time that corresponds to the current time that was stored in the RAM 12 at step S315, the period of time during which the roads within the basic range of the distribution, which was set at step S112 (probably will be unloaded.

If it is determined that the periods of the time the current time is not the period of time during which the roads within the basic range of the distribution, probably will not be loaded (S317: NO), the CPU 11 proceeds to the process at step S319.

On the contrary, if it is determined that the period of time that corresponds to the current time, is the period of time during which the roads within the basic range of the distribution, probably will not be loaded (S317: YES), the CPU 11 proceeds to the process at step S318. For example, if the period of time that corresponds to the current time falls in the middle of the night, the CPU 11 decides that the current time is within the period of time during which the roads within the basic range of the distribution, probably will not be loaded and proceeds to the process at step S318. At step S318, the CPU 11 performs the process of step S314, because there is a reserve in the amount of transmission traffic that matches the reference range, distribution, and proceeds to the process at step S319.

Then, in step S319, the CPU 11 performs the decision-making process to decide whether the search criteria of the route, which was received, priority, at least one the of the recommended roads and toll roads. If it is determined that the received search criterion of a route does not give priority recommended roads or toll roads (S319: NO), the CPU 11 proceeds to the process at step S321.

On the contrary, if it is determined that the received search criteria route gives priority to at least one of the recommended roads and toll roads (S319: YES), the CPU 11 proceeds to the process at step S320. At step S320, if the search criteria of the route gives priority to at least one of the recommended roads and toll roads, because there is a possibility that the main route can proceed any further, the CPU 11 sets the changed distribution band, increasing the base range of the distribution in an outward direction along the reference route. The CPU 11 then stores the new range of distribution in the RAM 12.

In addition, the CPU 11 reads the flag of the modified range of the distribution of the RAM 12 and assigns "1" is read, the flag of the modified range of the distribution, before re-save the modified flag of the distribution band in the RAM 12. The CPU 11 then proceeds to the process at step S321.

Next, examples in which the modified range of the distribution is set by increasing the base range of the distribution along the reference route, will be explained with reference to figa and 13B. Figa shows an example in which the modified range of the distribution is set by increasing the base range of the distribution in an outward direction along the reference route, positioned in the forward direction from the vehicle location. Figv shows an example in which the modified range of the distribution is set by increasing the base range of the distribution in an outward direction along the reference route, which includes the vehicle location and the reference location, which serves as the backbone for directions to the destination.

As an example, as shown in figa, when the search criteria of the route gives priority to at least one of the recommended roads and toll roads, because it is possible that the basic route 111 may continue on, the CPU 11 sets the changed distribution band 113, increasing in an outward direction range distribution within the basic range 112 distribution, which is positioned in the forward direction from the vehicle location, marked with 51 location of a vehicle. The CPU 11 then stores the modified range 113 distribution in the RAM 12.

As another p the iMER, as shown in figv, when the search criteria of the route gives priority to at least one of the recommended roads and toll roads, because it is possible that the basic route 115 from the vehicle location, marked with 51 vehicle location to the reference location 104, which serves as a support for directions to the destination, may proceed any further, the CPU 11 sets the changed range 117 distribution, increasing the base 116 range distribution, which includes the mark 51 of the vehicle location and the reference location 104, in an outward direction. The CPU 11 then stores the modified range 117 distribution in the RAM 12.

Then, as shown in figure 5, at step S321, the CPU 11 performs the decision-making process to determine whether the received search criteria, route priority, at least one of distance and common roads. If it is determined that the received search criterion of a route does not give priority to the distance or public roads (S321: NO), the CPU 11 proceeds to the process at step S323.

On the contrary, if it is determined that the received search criteria route gives priority to at least one of distance and common roads (S321: YES), the Central is hydrated CPU 11 proceeds to the process at step S322. At step S322, if the search criteria of the route gives priority to at least one of distance and common roads, because the basic route continues essentially directly to the destination, the CPU 11 sets the changed distribution band, reducing the base range of the distribution towards the inside along the reference route. The CPU 11 then stores the new range of distribution in the RAM 12.

In addition, the CPU 11 reads the flag of the modified range of the distribution of the RAM 12 and assigns "1" is read, the flag of the modified range of the distribution, before re-save the modified flag of the distribution band in the RAM 12. After that, the CPU 11 proceeds to the process at step S323.

Next, examples in which the modified range of the distribution is set by reducing the base range of the distribution towards the inside along the base of the route, will be explained with reference to figa and 14B. Figa shows an example in which the modified range of the distribution is set by reducing basic range distribution inside in the direction of the left and right width along the base of the route, while the location of the vehicle in its center. Figv shows an example in which the modified d is Amazon distribution installed by decreasing basic range distribution inside in the direction of the left and right width along the base of the route, moreover, the basic range of distribution includes the vehicle location and the reference location, which serves as the backbone for directions to the destination.

As an example, as shown in figa, when the search criteria of the route gives priority to at least one of distance and common roads, because the basic route 119 continues essentially directly from the vehicle location, marked with 51 location of a vehicle, the destination, the CPU 11 sets the changed range 121 distribution, reducing base 120 range distribution towards the inside along the reference route 119, in other words, inside in the direction of the left and right width. The CPU 11 then stores the modified range 121 distribution in the RAM 12.

As another example, as shown in figv, when the search criteria of the route gives priority to at least one of distance and common roads, because the basic route 123 continues essentially directly from the location of the vehicle, indicated by the label 51 vehicle location to the reference location 104, which serves as a support for directions to the destination, the CPU 11 sets the changed range of 125 races shall determine, reducing base range 124 distribution towards the inside along the reference route 123, in other words, inside in the direction of the left and right width. The CPU 11 then stores the modified range 125 distribution in the RAM 12.

Then, as shown in figure 5, at step S323, the CPU 11 performs the decision-making process to determine, based on the situations of the roads within the basic range of the distribution, which was set at step S112 (in other words, based on current information 16A traffic, which corresponds to the situations of the roads, there is information that is associated with obstruction to traffic, such as information about the accident or the management information traffic along the base of the route within the base range of the distribution, in other words, is there any obstruction to traffic, such as an alarm or control traffic in within the basic range of the distribution.

If it is determined that there are no obstacles to the movement of transport, such as accidents or traffic control transport within the base range of the distribution (S323: NO), the CPU 11 terminates the subprocess and returns to the main flowchart, to go to the process at step S119.

On the contrary, if defined, what is the obstruction to traffic, such as an alarm or control traffic within the base range of the distribution (S323: YES), the CPU 11 proceeds to the process at step S324. At step S324, if there is obstruction to traffic, such as an alarm or control traffic within the base range of the distribution, because you may need to detour, and the route will be longer in distance, the CPU 11 sets the changed distribution band, increasing the base range of the distribution in an outward direction. The CPU 11 then stores the new range of distribution in the RAM 12.

In addition, the CPU 11 reads the flag of the modified range of the distribution of the RAM 12 and assigns "1" is read, the flag of the modified range of the distribution, before re-save the modified flag of the distribution band in the RAM 12. After that, the CPU 11 terminates the subprocess and returns to the main flowchart, in order to continue the process at the step S119.

Next, examples in which the modified range of the distribution is set by increasing the base range of the distribution in an outward direction, in case where there is an obstruction to traffic, such as accident Il the management of traffic within the basic range, distribution, will be explained with reference to figa and 15B. Figa shows an example in which the modified range of the distribution is set by increasing the base range of the distribution in an outward direction, in case if there is an obstruction to traffic, such as an alarm or control traffic within the base range of the distribution. Figv shows an example in which the modified range of the distribution is set by increasing the base range of the distribution in an outward direction, in case where there is a barrier to traffic between the vehicle location and the reference location, serving as a support for the direction to the destination.

As an example, as shown in figa, when traffic control due to road construction 128, and the road is closed (shown by the reference position 129) because of an accident in the forward direction from the vehicle location indicated by the location of the tag 51 of the vehicle within the basic range 127 distribution, the CPU 11 sets the changed range 130 distribution, increasing the base range 127 distribution in an outward direction (for example, increasing the base range 127 distribution of 30 kilometers in each of the four on which rawline). The CPU 11 then stores the modified range 130 distribution in the RAM 12.

As another example, as shown in figv, when traffic control due to road construction 128, and the road is closed (shown by the reference position 129) because of an accident between the vehicle location indicated by the location of the tag 51 of the vehicle, and the control location 104 serving as a support for directions to the destination, within the basic range 132 distribution, the CPU 11 sets the changed range 133 distribution, increasing the base range 132 distribution in an outward direction (for example, increasing the base range 132 distribution at 30 kilometres each of the four directions). The CPU 11 then stores the modified range 133 distribution in the RAM 12.

Then, as shown in figure 3, at step S119, the CPU 11 reads the flag of the modified range of the distribution of the RAM 12. If the read flag of the modified range of the distribution is "0", the base range of the distribution, which was set at step S112 (used as a target allocation information of the traffic. The CPU 11 retrieves the current information 16A traffic, etc., including details what rmatio workload and information management traffic, which correspond to the categories of roads, which was set at step S113. The CPU 11 then stores the extracted information in the RAM 12 as a distributed information traffic, which is the information distributable navigation device 2.

Alternatively, after the CPU 11 considered the flag of the modified range of the distribution of the RAM 12, if the read flag of the modified range of the distribution is "1", the new range of distribution, which was set at steps S115, S117 or S118, is used as a target allocation information of the traffic. The CPU 11 retrieves the current information 16A traffic 16A and the like, including information load and information management traffic, which correspond to categories of roads, which was set at step S113. The CPU 11 then stores the extracted information in the RAM 12 as a distributed information traffic, which is the information distributable navigation device 2.

At step S120, the CPU 11 distributes the distributed information traffic navigation device 2, which corresponds to the ID that identifies the Navigator, which was obtained in step S111, ka is described above. Then, the CPU 11 terminates the process.

As explained in detail above, in the navigation system 1 according to the present variant implementation, when the CPU 11 provided in the center of the 3 distribution information received from the navigation device 2 vehicle information, such as ID, identifying the Navigator, the coordinate location data of the vehicle, the coordinate data of the destination and the search criteria of the route, together with the query command to query information traffic, such as current information 16A traffic, etc., including information load and information management traffic, the CPU 11 sets the category of the roads, which serves the purpose of information dissemination traffic based on one of the distance and time of movement from the vehicle location to the destination (steps S213-S219). Then, the CPU 11 retrieves the current information 16A traffic, etc., including information load and information management of transport flows, which correspond to categories of roads, which was established, and distributes the extracted information to the navigation device (steps S119-S120).

As a result, basing the ü on information of the vehicle, received from the navigation device 2, the CPU 11 sets the category of roads (e.g., roads, corresponding to a high standard, prefectural roads and major roads" or "all roads"), according to one distance and time of movement from the vehicle location to the destination. Thus, it is possible to set a category roads properly in accordance with the situation of the vehicle on which the navigation device 2. Consequently, it is possible to exclude information traffic that matches unnecessary categories of roads, and thus to keep communication costs low, ensuring that sufficient current information 16A traffic, etc. is distributed to the navigation device 2.

In addition, if the CPU 11 has determined that the vehicle on which the navigation device 2, is one that is defined as an Expressway and a toll road, the CPU 11 sets as categories of roads, which serves the purpose of allocation information of the traffic, such as current information 16A traffic 16A and the like, including information load and information driven the I transport streams, one of expressways and toll roads, and all roads, including small streets and any large roads, which are located in the vicinity of the exit from the Expressway or toll road. In addition, the CPU 11 sets the route on the Expressway or toll road, and the surrounding area of the exit from the Expressway or toll road as the new range of distribution (S211: YES through S212).

In the result, the CPU 11 distributes the navigation device 2 current information 16A traffic, etc., including congestion information and traffic management, route on the Expressway or toll road on which the vehicle is moving, as well as the surrounding area of the exit from the Expressway or toll road (steps S119 - S120). Thus, it is possible to exclude unnecessary information traffic to a great extent and, thus, to maintain communication costs at an even lower level, ensuring that allocated sufficient current information 16A traffic, etc.

In addition, the CPU 11 reads the time data, etc. from the timer 19 and receives the current date and current time. Thus, the CPU 1 identifies the factors associated with day of the week and time of day corresponding to the current time. If the CPU 11 determines that the time period corresponding to the current time, is the period of time during which the roads within the basic range, distribution will likely be loaded, the CPU 11 sets the changed distribution band, reducing the base range of the distribution towards inside (S315: YES through SS316). On the contrary, if the CPU 11 has determined that the period of time that corresponds to the current time, is the time period during which the roads within the basic range of the distribution is unlikely to be loaded, the CPU 11 sets the changed distribution band, increasing the base range of the distribution in an outward direction (S317: YES through S318).

In the result, the CPU 11 can set the range of the distribution, which is used to distribute current information 16A traffic, etc., including congestion information and traffic management, taking into account factors related to time, such as time of day. Accordingly, it is possible to set the range of the distribution for any of the periods BP is like, during which the road will probably be loaded to the amount of information for current information 16A traffic, etc. was at the appropriate level (for example, to the amount of information for current information 16A traffic, etc. was on predefined level). Therefore, it is possible to keep communication costs low, ensuring that allocated a sufficient amount of current information 16A traffic.

In addition, when the ratio of loaded links to all the links within the base range of the distribution exceeds the specified value (for example, 50%), since the volume of transmission traffic, such as current information 16A traffic, including congestion and information management traffic that matches the reference range of the distribution is large, the CPU 11 sets the changed distribution band, reducing the base range of the distribution towards inside (S311: YES through S312). On the contrary, when the ratio of loaded links to all the links within the base range of the distribution is equal to or less than a given value (for example, 10%), the CPU 11 sets the changed distribution band, increasing the base range of the soap the division in an outward direction (S313: YES through S314).

In the result, the CPU 11 can set the new range of distribution so that the amount of information for current information 16A traffic, etc. that must be distributed to the navigation device 2, was at the appropriate level (for example, the CPU 11 sets the changed distribution band so that the amount of information for current information 16A traffic, etc. was at a given level). Thus, it is possible to maintain communication costs at an even lower level, ensuring that allocated sufficient 16A current information traffic.

In addition, if the base range of distribution includes any range distribution, which does not contain links, the CPU 11 sets the changed distribution band, changing the base range of the distribution to exclude one or more ranges of the distributions within the basic range of distribution that do not contain ties (S 114: YES through S115).

In the result, the CPU 11 can set the new range of distribution so that the distribution ranges that do not contain links, such as mountainous areas, seashores and lakeshores were excluded, based on the current location the of vehicle and route. Thus, it is possible to eliminate current information 16A traffic, etc. that corresponds to the unnecessary distribution ranges, and thus, to keep communication costs low, ensuring that allocated sufficient current information 16A traffic, etc. that corresponds to a more effective range of the distribution.

In addition, when the area surrounding the location of the vehicle, contains such amount or more links, which may movement than the specified number, the CPU 11 sets the changed distribution band, changing the base range of the distribution so that the area surrounding the location of the vehicle was included in the new range of distribution (S116: YES through S117). As a result, the modified range distribution contains links, which may movement, which serve as many routes in the area surrounding the location of the vehicle, the CPU 11 can retrieve and distribute a sufficient amount of current information 16A traffic, etc. that you want to search for a route.

In addition, in the case where the CPU 11 has determined that there is a barrier to the movement of transport is, for example an alarm or control traffic within the base range of the distribution, because you may need a bypass and the route becomes longer the distance, the CPU 11 sets the changed distribution band, increasing the base range of the distribution in an outward direction (S323: YES through S324).

As a result, in the case when there is an obstruction to traffic, such as an alarm or control traffic within the base range of the distribution, you can distribute current information 16A traffic, etc. that corresponds to the changed range of the distribution, which is more than the basic range of the distribution. Thus, it is possible to allocate sufficient current information 16A traffic, etc. on the navigation device 2. Accordingly, the navigation device 2 may with a high level of accuracy to find a route that bypasses at a great distance obstacle to traffic, such as accident or management traffic.

In addition, in the case where the CPU 11 has determined that the received search criteria route gives priority to at least one of the recommended roads and toll roads, because it is possible that the basic route can prodolzhalis is further, the CPU 11 sets the changed distribution band, increasing the base range of the distribution in an outward direction along the primary route (S319: YES through S320). As another example, in the case where the CPU 11 has determined that the received search criteria route gives priority to at least one of distance and common roads, because the underlying route continues essentially directly to the destination, the CPU 11 sets the changed distribution band, reducing the base range of the distribution towards the inside along the reference route (S321: YES through S322).

As a result, the CPU 11 sets the changed distribution band, based on the search criteria of the route, the CPU 11 can set the new range of distribution, increasing the base range of the distribution in an outward direction, taking into account the possible continuation of the base of the route found by the search. Thus, it is possible to allocate sufficient current information 16A traffic, etc. in the navigation device 2. In addition, in the case when the underlying route continues to a considerable extent, according to the criteria of the route search, the CPU 11 can set the modified di is the range of the distribution, reducing base range of the distribution towards the inside along the route. Thus, it is possible to reduce the volume information for the data traffic, which corresponds to a modified range of the distribution, and thus to maintain communication costs at an even lower level.

The present invention is not limited to the above exemplary embodiment. Of course, you can apply various improvements and modifications to the present invention without deviating from the scope of the present invention.

(1) for Example, a possible configuration, according to which the range in which to search route has different levels, so that the category of roads that serve the purpose of information dissemination traffic, is set for each of the levels. An example of this configuration is explained with reference to Fig. Fig shows an example according to which the range in which to search route is set so that has different levels, so that the category of roads that serve the purpose of information dissemination traffic, is set for each of the levels.

As shown in Fig, the CPU 11 sets the ranges 137 and 138 of the distribution, which are the levels 0 and serve as a distribution of current is th information 16A traffic, etc. in the surrounding area (for example, within 30 kilometers from the location of the vehicle in the center) vehicle location, marked with 51 location of a vehicle, and in the surrounding area (for example, within 30 kilometers from the destination, 135, located in the center) destination 135, respectively. In addition, the CPU 11 sets the ranges 139 and 140, which are levels 1, having a predetermined width (for example, approximately 30 kilometers), and serve as a distribution of current information 16A traffic, etc. within the ranges 137 and 138 of the distribution. In addition, the CPU 11 sets the range of 141 distribution, which is level 2 and serves to distribute current information 16A traffic, etc. and surrounds ranges 139 and 150 distribution.

The CPU 11 sets the road category that serves the purpose of distribution for ranges 137 and 138 distribution, as all roads, including small streets and any large roads, and stores the category of the roads, which was installed in the RAM 12. In addition, the CPU 11 sets the road category that serves the purpose of distribution for ranges 139 and 140 of the distribution, as prefectural roads and most of the roads, and stores the category of the roads, which was installed in the RAM 12. Next, the CPU 11 sets the road category that serves the purpose of distribution for a range 141 distribution, as the roads are of a high standard, such as national expressways, urban expressways, roads are only for cars, toll roads and national highways identified by one and two digit numbers, and stores the category of the roads, which was installed in the RAM 12.

Then, the CPU 11 retrieves the current information 16A traffic, which corresponds to each of the categories of roads for ranges 137-141 distribution, and distributes the extracted information to the navigation device 2.

In the result, the CPU 11 distributes current information 16A traffic, etc. that corresponds to the categories of roads for each of the levels 0 to 2. Thus, it is possible to distribute current information 16A traffic, etc. that corresponds to the route search, carried out by the navigation device 2. In addition, since the category of roads identified for each of the levels from 0 to 2, you can reduce the amount of information for the data traffic and, thus, to keep communication costs low, UB is not, ensuring that sufficient current information 16A traffic, etc. is distributed to the navigation device 2.

As another modification example, a possible configuration, according to which if the vehicle is operated, is used as a sensor (called "car research"), so that the current information 16A traffic, etc., including load, is generated on the basis of information studies, such as speed (time/location)obtained from the vehicle research, history of motion for each vehicle research maintained so that information indicating which type of road user preferred car research, and whether the user wants to perform a detour to avoid a traffic jam on the road, can to be learned from the history of the movement. In this situation, at step S111, the search is carried out for the base of the route that is appropriate for the user of each vehicle research, so that you can establish a basic range of distribution and category of roads, which is used to distribute current information 16A traffic, etc.

With this configuration, the CPU 11 can retrieve and distribute current information 16A traffic, etc. that is specialized is Anna for a specific user, such as the user of each vehicle research. In addition, in order to be able to find a route that matches the preference of the user of each vehicle research, the link cost for a location of choice, reduced statistical information 16V traffic, so that the base route is established by conducting the route search based on statistical information 16V traffic. In this situation, you can retrieve the current information 16A traffic, etc., including congestion information and traffic management, and distribute the information retrieved for each vehicle research.

As another modification example, a possible configuration, whereby at step S12, the CPU 41 included in the navigation device 2, center 3 transmits the distribution information data associated with the history of the movement of the vehicle, which are stored in the database 38 of the history of the movement, together with the query command to query information traffic, such as current information 16A traffic, etc., including congestion information and traffic management. With this configuration, the CPU 11, predusmotren is in the center of the 3 distribution information, can extract from the data associated with the history of the movement information indicating what type of roads preferable for the user of the navigation device 2 and does not want the user to make a detour to get around the traffic jam on the road, based on data associated with the history of the movement, which was received along with the query command to query information traffic. In this situation, at step S111, the CPU 11 can retrieve and distribute current information 16A traffic, etc. that is specialized for the user of the navigation device 2. In addition, to ensure the possibility of finding a route that matches the preference of the user of the navigation device 2, the link cost for a location of choice, reduced statistical information 16V traffic, so that the base route is established by conducting the route search based on statistical information 16V traffic. In this situation, you can distribute current information 16A traffic, etc., including congestion information and traffic management, in the navigation device 2.

As another modification example, a possible configuration, whereby at step S11 the Central processor 41, included in the navigation device 2, performs the decision-making process to establish whether the button is pressed, the request, etc. for information request traffic, and the request button provided in the operating unit 24 is implemented, for example, touch screen or operating the switch. In this situation, if the request button or the like has not been pressed for information request traffic (S11: NO), the CPU 41 terminates the process.

On the contrary, when the request button or the like is pressed to request information traffic (S1l: YES), at step S12, the CPU 41 transmits to the center 3 distribution information ID that identifies the Navigator, the coordinate data of the current position of the vehicle and information version information 37A navigation maps together with the query command to query information traffic. After that you can perform, in accordance with which the CPU 41 performs the process at step S13.

In addition, in this situation, at step S111, the CPU 11 provided in the center of the 3 distribution of information, receives information, such as ID, identifying the Navigator, the coordinate location data of the vehicle information and version information 37A of navigation the second card, together with the query command to query the information of the traffic that has been transmitted from the navigation device 2. The CPU 11 then stores the received information in the RAM 12. After that, the CPU 11 performs the process at step S112 (.

Then, in step S113, the CPU 11 performs the process at step S211, as described above. Then, when the CPU 11 has determined that the vehicle in which the navigation device 2, is located on Expressway or toll road (S211: YES), the CPU 11 proceeds to the process at step S212. At step S212, the CPU 11 sets the Expressway or toll road as the road category that serves the purpose of information dissemination traffic, and stores the category of the road, which was installed in the RAM 12.

In addition, the CPU 11 sets the route on the Expressway or toll road as a modified range of the distribution, which is the range of distribution serving the purpose of allocation information of the traffic, instead of the base range of the distribution, which was set at step S112 (. The CPU 11 then stores the new range of distribution, of which the first was installed, in the RAM 12. Next, the CPU 11 reads the flag of the modified range of the distribution of the RAM 12 and assigns "1" is read, the flag of the modified range of the distribution, before re-save the modified flag of the distribution band in the RAM 12. After that, the CPU 11 returns to the main flowchart.

On the contrary, in the case where the CPU 11 has determined that the vehicle in which the navigation device 2, is not on the Expressway or toll road (S211: NO), then after executing the process at step S213, the CPU 11 returns to the main flowchart, without performing the process at step S214 through S219.

Then, the CPU 11 performs the process at step S114 through S117. After that, at step S118, after executing the process at step S311 through S318, the CPU 11 returns to the main flowchart, without performing the process at step S319 through S324. It is also possible configuration, according to which the CPU 11 terminates the process after executing the process at step S119 through S120.
