Method for regulation of transport flows on highway crossed by flows of vehicles moving transversely

FIELD: transport.

SUBSTANCE: road trains continuously moving via crossways are formed. Number of vehicles in a train and duration of traffic light permissive signal is set according to established average speed of trains traffic and length of intervals between crossways. Traffic interval between trains is set equal to time of traffic light permissive signal action which is the same for all crossways on the highway. Operation of traffic lights on adjacent crossways is performed in reverse phase. Approach of head vehicles of each train to crossway is performed at the moment when traffic light permissive signal switches on by means of scanning by train head vehicle drivers the information about time to traffic light permissive signal switching on from colour digital traffic light and other indicators installed in each running interval at side or at top. At the same time, this is the instrument to form volume of each road train. According to scanned from indicators information, drivers manually perform necessary vehicle speed correction or this correction is performed automatically. Maintaining quasiconstant number of vehicles in each road train in consequence of to their loss due to leaving the highway is performed by road train replenishment with vehicles from highway crossing directions under entrance traffic light permissive signal with joining to corresponding road train. This signal is switched on according to a signal from sensors carrying out permanent recalculation of vehicles in each road train at given loss of vehicles in a train.

EFFECT: higher throughput on a highway with crossways.

The invention relates to a method of managing movement of vehicles on highways, crossed by the streams of vehicles moving in the transverse direction, which movement at intersections regulated by traffic lights.

The known method and system for traffic management (PCT 92/18961). This solution improves the passage of traffic passing through the intersections through the use of control two-phase signals, and use the turning lane, which extends from the lane on one side of the traffic on the highway through the oncoming traffic lane and then along the edge of this oncoming lane of traffic approaches the intersection, so that the car could stand in a queue to turn right at the end of the headland after the appearance of the green signal, which creates a break in oncoming traffic, freeing to travel oncoming traffic lane.

The disadvantage of this technical solution is that it does not provide for the establishment of on-line continuous (non-stop) transport stream, and therefore, the highest possible throughput on the highway.

Closest to the proposed technical solution is the way to regulate traffic on roads with intersections in the form of so-called "green wave" (see, nab is emer, Kremenets Y.A. Technical means of traffic organization. M.: Transport, 1990). In accordance with this method, the green signals at traffic lights are included, depending on the speed of the cars on the track and adjustable distances between intersections, for which all traffic lights at intersections equipped with special sensors. It is believed that under these conditions, i.e. with adjustable this way intersections, cars provides non-stop travel on the road.

The lack of "green wave", as already shown, is the unreality of keeping the vehicle drivers impose speed in traffic on congested highways. In addition, when the "green wave" missing sync all traffic lights on the highway, without which it is impossible to simultaneously passing through the intersections of oncoming traffic.

The objective of the invention is to provide an on-line continuous, or continuous, motion in the velocity range of 60-90 km/h the cheapest and most effective means.

The technical result of the invention is to provide a high throughput on the highway - about 1,500 vehicles per hour per lane highway with speeding cars on mA is istruly in the range of 60-90 km/h with the organization on the highway simultaneous non-stop movement of transport streams.

The technical result is achieved in that in the method of regulating traffic flow on the highway, crossed by the streams of vehicles moving in the transverse direction, consisting in the use of control signals at intersections, form a separate column of vehicles moving through the intersection continuously, the number of cars in the convoy and the duration of the enabling signal lights set in accordance with the prescribed average speed of columns and the length of the sections between intersections, and the interval between the columns is equal to the time of operation enabling signal light, the same for all highway intersections, traffic lights adjacent intersections on the highway are out of phase, a supply head of the vehicles in each column to the junction produce by the time the enabling signal light by scanning the drivers head hire columns with svetozarevo of traffic lights and other signs, for example, with luminous display, installed on each of the driving side or top of the information about the remaining time until the occurrence of the enabling signal light that is both a means of creating a volume of each column, in accordance with a scanning drivers information with these pointers drivers produced the lead necessary correction vehicle speed manual or this adjustment is made automatically, maintaining a quasi-permanent number of vehicles in each column due to their losses at the expense of highway exits carry out replenishment of the convoy vehicles with cross-line directions for allowing the entrance on the line to signal incoming traffic lights attach to the corresponding column, allowing the entry signal includes the signal from the sensors, the leading constant recalculation of cars in each column, for a given decrease of the cars in the convoy.

In addition, set the speed on the highway in the range of 60-90 km/h

In addition, the conversion of the vehicles in the convoy are produced at each stage with walk-through detectors that generate signals when the vehicle is controlled in each detector zone on all lanes, fixing the fact of the appearance of the car, then carry out the data processing unit coming from all detectors, counting cars in the convoy and pass by means of the control device at a traffic light, a command to turn on allowing the entry of vehicles with transverse directions to the highway signal only at a 10 percent loss of hire of the already formed in accordance with the motion parameters and the parameters of the line of the column.

In addition, correction of the speed of cars on tracks based on the evidence placards produced automatically by reading the video sensor in the vehicle information display or lights, its processing and transmitting a corresponding signal to the sensor, speed controller, which produces the necessary change in the vehicle speed in accordance with the transmitted information about the time to change the sign of the light within the established interval velocities, the video sensor also receive information about the presence of pedestrians on the highway and take into account the safety distance to the neighboring vehicle with the transmission of commands to the vehicle's control systems.

Currently available standard equipment in the form of various sensors, in particular the contact detectors, electromagnetic detectors, radiation detectors; means of information processing and management, controllers, control traffic lights, and controls traffic, such as traffic lights, allows a relatively efficient and inexpensive to implement an ongoing process of information gathering detectors transport, processing, issuance controllers corresponding commands for the traffic lights to control the traffic on the highway in accordance with the proposed method. Thus, correlating the number of entering highway vehicles with speed or density of the transport stream, and in this case their number in the generated column hire, it is possible to keep the movement on the highway in the framework of the values of velocity or density of the transport stream, for example, in terms of velocity 60-90 km/h, if you can provide formed between the individual columns hire a movement interval equal to the duration of the enabling signal of the traffic light that allows for these additional terms to establish a continuous movement on the highway with oncoming lanes of traffic. The specified velocity range of traffic flow on highways, as will be shown below, is the most effective. On line no traffic jams and clearly maintained a distance between cars.

Evaluate first the process of the formation of traffic on highways in relation to one lane. In addition, for simplicity, all calculations will be given in the application to passenger vehicles.

Driver, moving at a certain speed along the lane, keeping a distance of safety. Its length depends on the speed and is determined from the following equation:

l=τ·v+v2/50,

where τ - time delay, i.e. the time of driver response to changing environmental conditions; v - speed of the car.

If the environment for the driver is stable and not bothering him, then, as experience shows, the average τ about 0.5 sec. on average, the time delay sohranaetsa the speed of the car from 30 km/h to 90 km/h

At lower speed for limit 30 km/h on a busy highways cars approach, you receive the kind of distress, which increases with decreasing speed. The situation on the road is becoming more complex, and the delay time increases. Experience shows that in this case τ increases to 1 C.

At high speeds, ranging from 90 km/h, physical and psychological stress of the driver increases as risk increases, and τ again increases to 1 C.

The reaction time of the driver τ, of course, depends on the experience and skill of the driver, but on average it is.

Figure v2/50 takes into account the variation of brake systems of cars.

The braking distance of the vehicle s=v2/2a, where a is a negative acceleration in m/s2. According to the technical requirements for modern vehicles and should not be less than 5 m/s2. The allowable variation is of the order of 10%. Let us take as example the worst case the vehicle in front is adjusted when braking on a=5.5 m/s2and the next vehicle is adjusted to a=4.5 m/s2. Then, if one car going at a speed of 25 m/s, will be held during braking v2/2a=625/9, another car will be the path v2/2a=625/11. The difference between these two segments is as follows: Δs=v2/9-v2/11=(11v2-9v2)/99=v 2/99~v2/50.

For example, at v=25 m/s (90 km/h) distance security l=0,5·25+252/50=12,5+12,5=25 m

We introduce the notion of dynamical length of the vehicle l. Dynamic length is the sum of the average physical length of the car ls and the safety distances l:

l=ls+l

The average physical length ls is 5 meters. Thus, the dynamic length l is the portion of the roadway, which is the car taking into account the safety distances l.

The ratio of vehicle speed to the dynamic length (v/l) is the bandwidth of the lane N.

For example, five cars move one behind the other at a speed of 90 km/h (25 m/s). They take 150 m lane (5 ed. × 30 m). When the specified speed, the distance of 150 meters will be covered for 6 seconds, then 6 seconds will pass all five cars. Thus, each vehicle is l (30 m) for 1.2 C. For one second the car will be 5/6 l (25 meters).

One hour throughput lane N at this rate, it will be 5/6×3000 = 3000 vehicles per hour.

At lower speed will change the dynamic length and bandwidth lanes. For example, if the cars are moving at the speed of 7.2 km/h (2 m/s) distance security l is 2.1 meters, that is, when the times of the delay τ=1 with the distance between the cars is a little more than 2 metres, dynamic length l - about 7 meters, and throughput N=2/7~0,3 author/s, i.e. it decreased three times with 5/6 author/s to 2/7 auth/S.

Throughput lane highway depending on speed change is not linear, it is important to select the most advantageous or optimal velocity range for establishing a continuous movement on the highway with regard to the use of the maximum value of its bandwidth.

Here is a table that will show the dynamic change of the length l, bandwidth N depending on the vehicle speed V in the velocity range from 2 m/s (7.2 km/h) up to 45 m/s (162 km/h). For comparison the table also change the number of vehicles n on a unit interval lanes, for example 1 km, depending on the speed V of the subject specified by us distance traffic safety l and the physical length of the vehicle, which together account for the dynamic length of the car l: n=1000 m/l.

From this table it is seen that the change of throughput lanes depending on the vehicle speed is non-linear in nature. At speeds of cars in the range from 10 m/s (~36 km/h) up to 25 m/s (90 km/h) throughput N maximum and varies slightly by about 5%. Why is the efficiency of use of highways for the movement of vehicles within this interval, the optimal speeds, moreover, this velocity range for establishing a constant of motion can be reduced to 60-90 km/h for the most favorable fuel consumption of vehicles and to reduce the time of the vehicle in the path.

We introduce the concept of traffic density γ, which is equal to the ratio of the physical length of the car to the dynamic length of the vehicle: γ=ls/l.

At v=25 m/s (90 km/h) l=25+5=30 m and γ=5/30=1/6~17%.

At v=17 m/s (60 km/h) l=14,3+5=19,5 m and γ=5/19,3=1/6~26%.

Therefore, a measure for the effective use of highways continuous movement is the task of providing traffic density in the range of 17-26%, which corresponds to the vehicle speed in the range of 60-90 km/h

Rate if bandwidth on the roads with intersections, where cars will be stopped by banning light, compared to the throughput on the same roads with intersections by providing them with cars without stopping.

The traffic management on roads with intersections is performed using traffic lights. When enabled, prohibiting signal transport stream is interrupted and the intersection accumulate cars. After switching enabling signal cars start moving sequentially: first moves first through second - second, t the th - after two seconds, etc. Thus, each vehicle is started in a second, because everyone needs to have a minimum distance of safety. For each subsequent vehicle increases the distance to the intersection. If we accept that the car behind the car take a period of 6 meters, the second car will move to the intersection of 6 meters, the third of 12 meters, etc. Calculation of acceleration shows that the second car will move to the intersection of one second, in total it would take him two seconds to advance to the intersection, the twentieth - 40 seconds. Therefore, every vehicle is consistently 2 seconds. In the end, if the enabling signal 40 seconds, during this time through the intersection will be one lane 20 cars, that is, the throughput of the intersection relative to one lane of traffic is 1/2 or 0.5 Veh/s But for permissive signal turns on prohibiting traffic light for 40 seconds. Thus, through the intersection for 80 seconds will pass 20 cars, and given pause to three-second intermediate signal yellow even less (~18), that is, throughput N=18/80=0,22 author/s=800 Veh/h

Result that the throughput of the intersection for one traffic lane is approximately four times lower throughput methods for the surface in one continuous lane at speeds in the range of 40-90 km/h

If all the cars at traffic lights for a complete cycle of the shift character (80) will not be able to pass, then the remaining waiting time is twice the average speed of cars on the highway falls under the same bandwidth backbone. Therefore, the efficiency of use of vehicles is further reduced because of this decrease speed.

Bandwidth lanes can be increased in two times, if you miss the car through the intersection on the move, or without stopping. Then each column of cars pass the intersection without stopping, but the average efficiency of vehicles will be two times lower, as between columns has a period equal to the duration of the light. However, compared to the normal movement of vehicles through intersections with traffic lights with excellent throughput in the organization of non-stop movement columns through intersections doubled from 800 Veh/h to about 1500 Veh/h due to the continuous movement of the columns one after another without stopping.

The proposed method of regulating traffic on the highway is that implemented the intersection traffic intersection immediately. It also provides maximum throughput for N intermittent the th transport stream. For this form the flow of vehicles with gaps, consisting of columns (pools)that immediately, one after another, observing interval is set to cross each intersection on the highway to allow the lights.

The first mandatory measure for this is that the phasing of the traffic flow, i.e. the solution supply head-end cars, each a separate column to the intersection by the time the enabling signal of the traffic light. This is achieved by informing the driver of the car in one way or another about the time remaining until the occurrence of the enabling signal lights. Drivers head cars and drivers that follow the first, seeing the time remaining until the occurrence of the enabling signal, or otherwise manipulate the speed of the vehicle and thereby provide an approach to an intersection of the head car of the convoy by the time the enabling signal of the traffic light. Correction speed of cars on tracks based on the evidence placards can also be produced automatically by reading the video sensor in the vehicle information display or light, its processing and transmitting a corresponding signal to the sensor, speed controller, which produces the necessary change in the vehicle speed in accordance with the plumage is havemay information about the time to change the sign of the light within the established interval velocities, the video sensor also receive information about the presence of pedestrians on the highway and take into account the safety distance to the neighboring vehicle with the transmission of commands to the control system of the vehicle (see, for example, patent RF №2317592).

When using tools phasing transport stream all the lights of the highway have the same cycle or the same duration of the enabling signal, which provides the same number of cars in the convoy and the same passage of the column through all the intersections, that is, when prohibiting signal in the column will not accumulate additional cars. In addition, it will provide the synchronization of the movement of counter-flows of vehicles on the highway.

The duration of the enabling signal corresponds to the speed of traffic flow between intersections is about 75 km/h in bridging the average length of haul.

The lights of neighboring intersections of the line are out of phase.

While moving on the highway part of the car leaves the line and reduces the number of cars in the convoy. Therefore, to maintain high efficiency of the use of highways and high-efficiency vehicles will need to adjust the number of cars in the convoy.

Because the duration of the enabling signal at all intersections are the same and since when measuring speed in the range of 10-25 m/s bandwidth lanes N varies by no more than 5%, it is advisable to provide approximately constant number of cars in the convoy. For example, time permitting light to 40 seconds. Then with capacity of 3000 Veh/h, or 5/6 author/s on each lane through the intersection (5/6×40) will be not more than 33 cars. Then, when the three-way line in the column will be about 100 cars

To regulate the number of vehicles in the convoy uses the standard sensors of a particular type, for example-through detectors, which generate normalized by the duration of the signals when the vehicle in a controlled sensors zone. Thus, the detector detects the occurrence of the vehicle (see, for example, 1. Kremenets Y.A. Technical means of traffic organization. M.: Transport, 1990 2. Klinkowski GI, Afanasiev MB traffic: the textbook for high schools. M.: Transport, 1992). Such bushing detectors measure the number of cars in the convoy, process and transmit the information to the control device, which gives the command to activate the enabling signal of the incoming light from the lateral direction only when the number of vehicles in the convoy, for example, by 10% (from 100 cars in this example, up to 90) and switches the incoming signal light in prohibiting, when the number of cars in the convoy in sstanovitsja (up to 100) at the expense of the entered cars. The combination of this equipment is at each intersection local machine motion control.

Practically the number of vehicles in the convoy is determined by the parameters of the line and the duration of the enabling signal lights.

It should be noted that stop certain cars are not dangerous, as these cars are cut off from one column and join another. And unequal length of the sections between intersections and possible dissimilarity prohibiting movement signals are compensated by the change of speed of movement of the column between the intersections.

Local machines motion control are virtually Autonomous. At the junction of highways between a work machine adjacent highways consistent with each other. In this case turns out to be a preference for one of the highways, referring to the moving part of the flow from one line to another.

The set of machines highways and machines of all lines are distributed automatic control system all roads of the city.

To inform drivers about the time of switching of a traffic light in different ways. For example, before the advent of enabling signal to enable a yellow signal or big numbers against the red signal to inform about the remaining time until the appeared who I allow (green) light.

The most reliable seems to be svetozarevo way of information drivers about changing the sign of the traffic light. However, the information on the traffic light can be duplicated in large svetozarovym indicators (Board), established with a certain interval, for example every 100 meters, on the stretch on the sides or top. Such boards not only inform drivers about the time remaining until the switch of the light, but to form a column of vehicles passing the entire intersection at the time the enabling signal lights. In addition glowing signage can be used to read them a video sensor mounted on the moving driving the vehicle, information about the time remaining before switching traffic light, to transmit a corresponding signal to the sensor controller speed, installed on the vehicle, and the sensor controller automatically, i.e. without participation of the driver, produces a corresponding adjustment of the speed of the vehicle for safe travel within the established interval of speeds of 60-90 km/h in the column through the intersection.

Speed limits when driving columns at regular intervals on the highway does not create conditions for the emergence of the tubes. However, the proposed method can significantly reduce the number drainageproject, as with the velocity clearly maintained a distance between cars.

In order sliding down the highway the car doesn't slow down the speed of the movement of the other cars at the traffic lane, close to the exit areas can be selected zone drives that before you exit and enter the car, without hindering the movement of other vehicles on the highway. These zones, depending on the characteristics of the highway, can be calculated by 10-20 cars. In the case of continuously operating in the hard mode, movement routes, for example a ring, and a large number of sliding down the car all the far lane is exempt from movement and is used only to Congress and, if necessary, for the movement of public transport.

At the junction of highways between a local automatic control movement of the adjacent roads will agree among themselves. In this case turns out to be a preference for one of the highways, referring to the moving part of the flow from one line to another. When local control switch provides signals to the controller, located directly at the intersection, it is also Possible system management, in which each entry of land use data transport is on stream with other entry areas to further improve the effectiveness of the highway. When the system management controllers intersections can serve as translators teams coming through special channels from the control point

The set of machines highways and machines of all lines is a distributed automatic system of control of all highways of the city.

The invention makes maximum use of existing highways cities and urban road networks due to the fact that the speed of vehicles on highways is kept in the optimum range, which allows maximum use of available bandwidth of the trunk, that makes the effectiveness of each line the highest and, thus, passes it the maximum number of vehicles with the most beneficial rate. While to a certain extent, unloaded the rest of the road network.
