The invention relates to the field of motion control of vehicles and, in particular, to the selection of routes, taking into account the workload of the road sections.

There is a method of determining the optimal route of the vehicle on the road network of the settlement, (RF patent 2153194), which is that in the computer memory of the subscriber entered the electronic map of the road network of the settlement, on the basis of prior motion parameters determine the average speed indices at each site traffic from an external source (preferably, the Central station) preferably receive the channel information which is considered relevant (hereinafter referred to relevant information), the velocity in the movement of vehicles, and then adjust the speed of the indices of those sections of the road network, which has up to date information on the communication channel transmit information about the adjusted speed indexes other subscribers, according to the data of the destination subscriber (in the computer memory of the subscriber enter the data on the destination) determine the preferred route in accordance with the updated speed index sections of the road network of the settlement, along a selected route, in case the modify of speed indexes stretches of the road network locality adjust the optimal route to the destination.

The shortage of this method is low the probability of selecting the optimal route in terms of traffic in the modern metropolis.

The method is able to calculate and allow to choose routes that are close to optimal, in conditions of relatively free movement with a small number of sites with obstruction. In such conditions the computational difficulty of the movement. In such conditions, the computing device (PC) subscriber after receiving the information about the correction speed of the indexes of the relevant sections of the road network will rely and build a route to bypass areas with low speed indexes. Although the length of the route at the same time will increase, but the travel time will be reduced by increasing the speed. Because current information about the speed of traffic is present only for part of the stations, the route in General will also pass through areas for which no information. However, even if no actual information about the speed of traffic on the streets for the construction of a detour, the chance to meet there a site with difficult movement compared with the statistical average value is small, because in General the traffic on most streets freely, i.e. information obtained from sensors on a moving vehicle when edstac, lets bring the route to optimal.

The situation changes drastically in the modern metropolis, especially during peak hours or during adverse weather conditions. In this environment, the relative number of sites with free movement a little. And the probability that the area with missing relevant information the actual speed is below the statistical, great. Under these conditions, the detour section with difficult traffic on adjacent streets, as in the previous example, with a high probability can not only lead to a longer route, but also to increase the time spent in the way, because on the streets, which is a detour, the movement can be less difficult, but this information is missing. That is, the probability of constructing a route that is close to optimal, in heavy traffic is reduced.

The technical result of the invention is the reduction in the average time of the route in heavy traffic.

They form a map-controlled road network by assigning the calculated speed index sections of the road.

Periodically (with a pre-assigned frequency) accept information from stationary and non-stationary sensors of speed on parts of sections of road CE and (this information is considered relevant and is used as the basis for the recalculation and adjustment of the speed of the indexes of the relevant sections of the road network).

Controlled road network is divided into one or more fields.

Within each area for part or all sections of the road network for which you have carried out the correction of the speed index on the basis of current information, calculate the average velocity Vawithout the performed correction and the average velocity Vbbased on conducted correction and calculate the ratio X=Vb/Vain the absence of such sections of the road network the ratio X is set to 1.

Within each area for each section of the road network, for which no correction was carried out in the speed index on the basis of current information, recalculate speed index by multiplying the speed of the index this section of the road network on the function of Ka(X)from the relations X=Vb/Vaand for each section of the road network that has been the correction of the speed index on the basis of relevant information, conduct additional conversion speed index by dividing the adjusted speed index this section of the road network on the function of Kb(X)from the relations X=Vb/Va.

The functions Ka(X)and Kb(X)choose from the following properties: Kb(X)>0, K(X)=Ka(X)∗Kb(X)represents a function is with the following properties: 0< K(X)<1 when X=0, K(X)a non-decreasing function when X>0, K(X)=1 when X=1, K(X)≤X when X>1.

Get data about the current location of the subscriber and the destination point and calculate the recommended route, based on the adjusted speed index sections of the road network.

Function of Kb(X)for most cases, can be chosen from the condition Kb(X)=1 for all X.

Function of K(X)can be chosen from the condition K(X)=X when X>1.

Function of K(X)can be chosen from the condition K(X)=1 if X>1.

In addition, K(X)can be chosen from the condition K(X)=a+(1-a)∗X when 0<X<1, where a is chosen from the condition 0<a<1.

The relation X=Vb/Vait can be calculated only on those sections of the road network, for which correction was carried out high-speed indexes based on current information, which are pre-assigned for each area a list of sections of the road network.

Area or areas that break-controlled road network, can be populated, areas of settlement, linked sites traffic, etc.

The average speed for each area can be calculated in various ways. Most preferred is the use of weighted arithmetic or harmonic from the front, where as weight using the length of the corresponding plot. The second method is equivalent to the inverse value of simple and weighted average travel time per unit length in each plot, where as weight also use the length of the plot. Can be used and more complex weight. For example, each section of the road can be assigned a rank according to the degree of influence or communication traffic with the overall traffic situation and the situation on the adjacent road sections. To assign a rank you can use the method of expert estimates or statistics. In this case, as the weight can be used the product of the rank on the length of the corresponding segment.

With a large number of sections of the road network in each region, the calculation of the coefficient of X it is enough to spend on a sample that includes only the parts of the road network, for which correction was carried out high-speed indexes based on actual information. The sample may be implemented in various ways: random sampling, sampling sections of the road network with the highest rank, or a selection of only those sections of the road network, which are pre-defined (assigned) a list of the most representative for each region stretches of the road network. This list can be drawn up, which, for example, the method of expert estimates or using statistical data.

The benefits of reach due to the fact that having information about the change in the average value of current (i.e., obtained from external sources, mainly sensors) speed index plots of the road compared co the speed index of the same plots without taking into account relevant information, adjust in the same direction and speed indexes on those areas for which there is no relevant information. The likelihood of this assumption is growing rapidly with increase in the size of the sequence and sampling. If the area will contain, for example, 1000 streets, statistical values of the velocity are known, and to a random sample of 300 streets will record a twofold reduction of the average speed on current data, the probability of the assumption that the average speed on the remaining 700 streets at the moment too less close to 1. Thus, adjusting the speed index plots of the road, for which there is no relevant information, based on the change in average speed indexes sites that have relevant information, statistically increase the adequacy of high-speed indexes used for the optimal route.

As for laying the optimal Mar the Ruta important not so much in themselves the absolute values of the velocities of different parts of the road, how many of them the ratio, the more General case, to achieve a positive effect, it is possible to pererastayut (correct) speed plots for which no relevant data, in direct dependence on the coefficient of X, and the actual data speeds those areas for which there is actual data in reverse correlation coefficient X.

For simplicity, first consider the case when pererastayut only high-speed indexes roads, for which there is no actual information about the speed. This corresponds to the case of selection functions Kb(X)=1.

Recalculation is carried out by multiplying the speed of the indexes of the respective road sections on the function of Ka(X)that depends on X, that is, from changes in the relationship of average velocities for the same road sections after receiving relevant information and without registration.

The simplest and closest to the practice can be considered as the choice of the function Ka(X)=a+(1-a)∗X. This means that the velocities in areas for which no information is changed linearly in the same direction as the ratio of average velocity X. When X=1, when the average speed with up to date information and without it are the same, Ka(1)=1 and the correction is missing.

For small values of a speed sections of the road, for which there is no relevant information, reduce practice the Eski proportional to X. This means that you need to reduce speed on these sites about the same time, much decreased average current speed for areas where such data are available.

For large values of a correction degree decreases. In the more General case, when X<1, if the graph of the function Ka(X)buckle up relative to Ka(X)=X, it means trailing the degree of correction, and down - ahead. A surpassing degree correction means for laying the optimal route preference will be given to routes where a large part of the route goes along sections of the road with a known current speed.

When X>1, on the contrary, if the graph of the functions Ka(X)buckle up relative to Ka(X)=X, it means a quicker correction degree, and down - delayed. The value function Ka(X)limited to Ka(X)≤X, since there is no reason to increase the probability of route sections of the road with an unknown current speed conditions, when the average traffic on sites with known current speed freely.

All of the above is true for the more General case, when the correction is carried out simultaneously using the functions Ka(X)and Kb(X), with the only difference that all the previously mentioned function of Ka(X)heat the R refers to the functions K (X)=Ka(X)∗Kb(X). As a function of Ka(X)multiply the velocity plots for which there is no relevant information, as a function of Kb(X)divide the actual speed values of those areas for which these values are known, after carrying out the allocation ratio of the speeds in all areas of the road will be the same as in the above special case, when Kb(X)=1.

The choice of specific values of functions Ka(X)and Kb(X)depends on specific technical implementations calculate the optimal route using this method. For example, if it is important (for example, for the visual display)to rate plots of the road most adequately reflect the traffic situation, it is necessary to choose Kb(X)=1.

If it is important to optimally calculate the route on the hardware of the mobile client, the local map is based on the statistical rate plots of traffic and which receives from the outside (for example, on a wireless communication channel from the Central server) data on current velocity plots of the road, it may be expedient choice of Ka(X)=1. This choice allows server-side, which has the same card, to adjust only the actual data speed is by dividing the function of K b(X), which is then sent to the mobile client. Mobile client when you don't have to do any additional operations when calculating the best route.

The applicant held the patent information search, which is not identified technical solutions containing the claimed combination of features. Therefore, the technical solution can be considered new. The prior art is unknown and it is not obvious to a person skilled impact on this technical correction speed indexes sites traffic with unknown actual speed indexes for changes in the statistical characteristics of the areas for which such information is available, as well as the manner in which such correction is carried out. Therefore, the proposed solution meets the criterion of "inventive step".

The implementation of the method is as follows.

They form a map-controlled road network with speed index plots of the road.

Accept information from external sources (stationary and non-stationary sensors) about the speed of movement on the part of sections of the road network and based on this latest information correct speed indexes of the relevant sections of the road network.

Controlled traffic behold the ü is divided into one or more areas. Within each area for part or all sections of the road network, for which correction was carried out high-speed indexes based on current information, calculate the average velocity Vawithout the performed correction and the average velocity Vbbased on conducted correction and calculate the ratio X=Vb/Va. In the absence of such sites within the area road network the ratio X is set to 1.

Within each area for each section of the road network, for which there was carried out the correction of the speed index on the basis of current information, correction speed index by multiplying the speed of the index this section of the road network on the function of Ka(X)from the relations X, and for each section of the road network that has been the correction of the speed index on the basis of relevant information, conduct additional speed correction index by dividing the adjusted speed index this section of the road network on the function of Kb(X)from relations X.

Choose the functions Ka(X)and Kb(X)with the following properties:

Kb(X)>0,

and K(X)=Ka(X)∗Kb(X)is a function with the following properties:

0<K(X)<1 when X=0, K(X)non-decreasing function of the ri X> 0,

K(X)=1 when X=1,

K(X)≤X when X>1.

According to the current location of the subscriber and the destination point and calculate the recommended route, based on the adjusted speed index sections of the road network.

Function of Kb(X)can be chosen from the condition Kb(X)=1 for all X.

In addition, K(X)can be selected from conditions

K(X)=X when X>1 or

K(X)=1 if X>1.

In addition, K(X)can be chosen from the condition K(X)=a+(1-a)∗X when 0<X<1, where a is selected from the conditions 0<a<1.

The relation X=Vb/Vait can be calculated only on those sections of the road network, for which correction was carried out high-speed indexes based on current information, which are pre-compiled for each area a list of sections of the road network.

Area or areas that break-controlled road network, may be the town in General, areas of settlement, linked sites traffic, etc.

The average speed for each area can be calculated in various ways. The benefits will still be achieved. Most preferred is the use of weighted arithmetic or harmonic average, where the weights using length matched with the existing plot.

The second method is equivalent to the inverse value of simple and weighted average travel time per unit length in each plot, where the weight is also used length of the plot. Can be used and more complex weight. For example, each section of the road can be assigned a rank according to the degree of influence or communication traffic with the overall traffic situation and the situation on the adjacent road sections. To assign a rank you can use the method of expert estimates or statistics. In this case, as the weight can be used the product of the rank on the length of the corresponding segment.

With a large number of sections of the road network in each region, the calculation of the coefficient of X it is enough to spend on a sample that includes only the parts of the road network, for which correction was carried out high-speed indexes based on actual information. Sampling can be done in different ways: randomly, to use the road network with the highest rank, or only those parts of the road network, which are pre-defined (for example, the method of expert estimates or using statistical data) for each area a list of the most representative areas of the road network.

A device that implements the claimed method involves the Central nervous system, the e computing and coordinating device, associated with coordinating device via the communication channels, the speed sensors traffic on all or parts of sections of the road network associated with a coordinating device via the communication channels personal computing (mainly mobile) devices (primarily vehicles)involved in road traffic.

The device operates in accordance with the described method.

FIELD: physics; computer engineering.

SUBSTANCE: invention relates to traffic control and involves sending navigation instructions to a vehicle with a monitor which displays a map. According to the disclosed method, an electronic speed map of the road network of a residential area is made, where the said map, which is stored in a central station computer, shows the average traffic speed on each road. A road graph is made on the said map. Data of the road graph are corrected based on information on changes of road signs. Actual values of average speed on at least one segment of the road graph are sent from computers in the vehicles over a radio channel with given periodicity to the computer at the central station, and average traffic speed is determined from the said values. Further, deviation of actual values of average speed from model speed on the segment of the road graph are subtracted, and "jam" and "anti-jam" files are made from the said deviations. Taking into account these files and the weight of right and left turns, the model electronic speed map of the road network of the residential area is corrected. The recommended optimal route is determined taking into account specified parametres of the electronic speed map of the road network of the residential area, which is received by a subscriber from the central station with possibility of displaying the said routes on the said map on a monitor and displaying current position of the vehicle.

EFFECT: more accurate determination of a time-optimal route for a vehicle.
