Description

Traffic jam processing method, device, equipment and medium

Technical Field

The present application relates to the field of traffic signal control technologies, and in particular, to a method, an apparatus, a device, and a medium for processing traffic congestion.

Background

With the increase of the urban scale, the demand of vehicles in urban traffic for traveling is continuously increased, and the problem of traffic jam is followed. In order to solve the problem of traffic jam in the prior art, an image acquisition device acquires an image, and after the image is acquired, the position information of vehicles in the acquired image is determined through a pre-trained classification model, so that the number of vehicles on the current road section, namely the jam information of the vehicles, is determined; or the number of vehicles on the current road section is obtained through data collected by a Radio Frequency Identification (RFID) vehicle induction module. After the number of vehicles on the current road section is obtained, the algorithm processor determines the conversion time of the traffic light according to the number of vehicles on the current road section and sends the conversion time to the processor. And finally, the processor sends the conversion time to each traffic light device, so that the conversion time of the traffic lights is controlled, and the problem of traffic jam is relieved through the conversion time of the traffic lights. However, in the prior art, only the current road segment is considered, and if only the traffic light of the current road segment is controlled, it is difficult to effectively solve the problem of traffic congestion, and meanwhile, overflow or deadlock may occur on other road segments around the current road segment.

In order to effectively solve the problem of traffic jam, in the prior art, a worker commands a vehicle on a jammed road section or controls a signal lamp of the jammed road section on a signal control platform. However, when a vehicle is commanded by a worker or a signal lamp is controlled by the worker on a signal control platform, the upstream and downstream road sections cannot be scientifically and reasonably coordinated due to manual control, so that resource waste is often caused, the queuing length of a non-control road section is long, and balanced control cannot be achieved.

Fig. 1 is a schematic diagram of a traffic congestion processing process provided in an embodiment of the present application, where the process includes the following steps:

s101: acquiring a first queuing length of vehicles on a current road section acquired by preset acquisition equipment; and judging whether the first queuing length exceeds a preset congestion length threshold value.

The traffic jam processing method provided by the embodiment of the application is applied to electronic equipment, and the electronic equipment can be intelligent equipment such as a PC (personal computer) or a server.

In the embodiment of the application, the electronic device determines whether the current road section is congested or not according to the acquired first queuing length of the vehicles on the current road section acquired by the preset acquisition device. The preset acquisition device is arranged at a fixed position of the current road section, and the preset acquisition device can be a radar device, an image acquisition device and the like. Specifically, how to acquire the queuing length of the vehicles on the current road section through a radar is the prior art; how to determine the queuing length of the vehicles on the current road section according to the image acquired by the image acquisition device is the prior art, and details are not repeated here.

After the electronic equipment acquires the first queuing length of the vehicles in the current road section acquired by the preset acquisition equipment, whether the current road section is congested or not is judged according to the acquired first queuing length. Specifically, the electronic device stores a preset congestion length threshold, and the electronic device determines whether the acquired first queue length exceeds the preset congestion length threshold.

S102: if the first queuing length exceeds a preset congestion length threshold, increasing the duration of the green light of the current road section on the basis of the original duration, and increasing the duration of the green light of each evacuation road section corresponding to the current road section by a first preset duration; acquiring collected ORIGIN and DESTINATION (OD) data of the current road section, and acquiring a first number of vehicles in the current road section according to the OD data; determining, from the source road segments of each vehicle, a second number of vehicles of the current road segment that originate from each source road segment; for each source road segment, determining a target ratio of a second number of vehicles in the current road segment from the source road segment to the first number; and shortening the duration of the green light of the source road section by the duration corresponding to the target ratio according to the corresponding relation between the ratio and the duration which is stored in advance.

In the embodiment of the application, after the first queuing length is acquired, whether the first queuing length of the vehicles on the current road section is a preset congestion length threshold is judged, and if the first queuing length exceeds the preset congestion length threshold, congestion occurs on the current road section. The duration of the green light on the current road section is increased on the basis of the original duration. The duration of increasing the duration of the green light on the current road section can be any duration, the duration of increasing the duration can also be a fixed duration in convenience, or a smaller duration, and the like, and can be flexibly set according to needs when being applied. And increasing the time length of the green light of each evacuation road section corresponding to the current road section by a first preset time length, namely increasing the leaving time length of the vehicle in the current road section, and avoiding the sending congestion of the road section near the current road section. The original time length of the road section green light refers to the time length when the time length of the road section green light is not adjusted, for example, the time length when the time length of the certain road section green light is not adjusted is 10 seconds, and the original time length of the road section green light is 10 seconds.

If the current road section is provided with the device for collecting the OD data, the number of vehicles from each source road section in the current road section can be obtained according to the collected OD data. For each source road section, if the number of vehicles in the current road section from the source road section is large, the green light duration of the source road section can be shortened a lot, and if the number of vehicles in the current road section from the source road section is small, the green light duration of the source road section can be shortened a little. Therefore, the vehicle-coming time of the vehicles in the corresponding source road sections with higher number is effectively controlled, and other corresponding source road sections with lower number are not influenced to the greatest extent.

In this embodiment of the application, in order to accurately adjust the duration of the green light of each source road segment, for each source road segment, the duration corresponding to the target ratio may be determined to be the duration shortened by the green light of the source road segment after determining the target ratio corresponding to the source road segment according to the target ratio of the second number of vehicles in the current road segment from the source road segment to the first number of vehicles in the current road segment. Wherein, the larger the ratio is, the longer the corresponding time length is.

Specifically, the determining of the ratio of the second number of vehicles in the current road section, which are from the source road section, to the first number of vehicles in the current road section, and the determining of the adjustment of the duration of the green light of the source road section according to the ratio may be: and after the source road section of each vehicle is obtained, determining a second number of vehicles of the current road section from each source road section according to the source road section of each vehicle. And after determining the first number and the second number, determining a target ratio of the second number to the first number, where the target ratio is a ratio of vehicles in the current road segment that originate from the source road segment. And after the target ratio corresponding to the source road section is determined, determining the duration corresponding to the target ratio according to the corresponding relation between the ratio and the duration stored by the electronic equipment, and shortening the duration of the green light of the source road section by the duration corresponding to the target ratio.

When determining the source road section corresponding to the current road section, each source road section of the vehicle source in the current road section can be determined through the OD data acquired by the OD data acquisition device, so that whether the current road section is provided with the OD data acquisition device or not can be judged, and if the current road section is provided with the OD data acquisition device, the source road section of each vehicle in the current road section can be determined to be the source road section of the current road section according to the OD data acquired by the OD data acquisition device arranged in the current road section.

In the embodiment of the present application, if the source road segment is determined according to the OD data, it may be directly determined which source road segment is the first-level source road segment, which road segment is the second-level source road segment, and which road segment is the other-level source road segment according to the identifier of the sequence of the vehicle passing through the road segments stored in the OD data. The device for collecting OD data may be an electric alarm camera, and specifically, how to collect OD data by the electric alarm camera is the prior art, which is not described herein again.

In this embodiment, the source segments of the current segment may include a primary source segment, a secondary source segment, and a tertiary source segment. For each road section, if the vehicle passes through the road section and then directly reaches the current road section, the road section is a primary source road section, and if the vehicle passes through some other road section after passing through some other road section and then directly reaches the current road section after passing through some other road section, the road section is a secondary source road section. If the vehicle passes through a certain other road section after passing through the road section, passes through another other road section after passing through the certain other road section, and reaches the current road section after passing through the another other road section, the road section is the third-level source road section. In this embodiment, the source segment may be referred to as an upstream segment, and 3 upstream segments may be used to represent a primary source segment, a secondary source segment, and a tertiary source segment.

For example, when the vehicle travels through the a road section, the B road section, and the C road section in sequence, and the C road section is the current road section, the B road section is the primary source road section of the C road section, the a road section is the primary source road section of the B road section, and the C road section is the secondary source road section of the C road section, that is, the B road section and the a road section are both the source road sections of the C road section, and the green light durations of the a road section and the B road section can be adjusted during adjustment.

According to the method and the device, when the fact that the first queuing length of the current road section exceeds the preset congestion length threshold is detected, the time length of the green light in the source road section is shortened, the time length of the vehicles coming in the congested current road section is reduced, the number of the vehicles coming in the current road section is controlled, the time length of the green light in the current road section and the time length of the green light in the evacuation road section is increased, and the time length of the vehicles leaving the current road section is increased, so that the problem of congestion of the current road section can be effectively solved.

In order to effectively solve the problem of congestion of the current road segment, on the basis of the above embodiment, in the embodiment of the present application, the method further includes:

after the duration of the green light of the current road section is increased on the basis of the original duration, acquiring a second queuing length of the vehicles on the current road section, which is acquired by the preset acquisition equipment;

and if the second queuing length exceeds the congestion length threshold, outputting alarm information.

In the embodiment of the application, after the set time interval after the adjustment of the green light time length of the current road section, whether the adjustment of the green light time length of the current road section has an effect on congestion of the current road section is detected, and if the congestion of the current road section has no effect, alarm information is output.

Specifically, after the set time interval after the green light duration of the current road section is adjusted, that is, after the set time interval after the green light duration of the current road section is increased on the basis of the original duration, the electronic device obtains a second queuing length of the vehicle in the current road section, which is acquired by a preset acquisition device, and determines whether the adjustment of the green light duration of the current road section has an effect on congestion of the current road section according to whether the acquired second queuing length exceeds a preset congestion length threshold. If the second queuing length exceeds the preset congestion length threshold, the green light of the current road section is adjusted, no effect is achieved on congestion of the current road section, the current road section is still in a congestion state, intervention of workers is needed, and alarm information is output.

Specifically, the electronic device can output alarm information to preset equipment, and congestion of the current road section is solved manually. That is to say, if the duration of the green light of the current road segment is adjusted, but the current road segment is still in a congestion state, sending alarm information to the preset device, where the alarm information may include an identifier of the current road segment. The alarm information informs workers that risks such as overflow possibly exist in the current road section, and the workers can monitor the road section corresponding to the identification carried in the alarm information through the video after receiving the alarm information, so that whether risks such as overflow exist in the current road section or not can be checked and confirmed. The preset device can be a mobile terminal of a worker.

In order to effectively solve the congestion degree of the current road segment, on the basis of the foregoing embodiments, in an embodiment of the present application, if the second queuing length does not exceed the congestion length threshold, the method further includes:

judging whether the second queuing length exceeds a safety length threshold value or not;

if not, determining that the green light duration of the current road section, each source road section and each evacuation road section is the original green light duration of the current road section, each source road section and each evacuation road section respectively;

if so, increasing the duration of the green light of the current road section on the basis of the original duration; when the second queuing length exceeds the safety length threshold, the increased green light time of the current road section is longer, and when the first queuing length exceeds the preset congestion length threshold, the increased green light time of the current road section is shorter.

In the embodiment of the application, after the duration of the green light on the current road section is adjusted, if the second queuing length does not exceed the congestion length threshold, it is described that congestion on the current road section is relieved, and whether the congestion degree of the current road section is effectively relieved or not is further determined, where the fact that the congestion degree of the current road section is not effectively relieved means that the congestion degree of the current road section is lighter than the congestion degree when congestion is caused, but is not completely relieved. And judging whether the second queuing length of the vehicles on the current road section acquired by the preset acquisition equipment exceeds a preset safe length threshold value. The preset safe length threshold may be a fixed multiple of the preset congestion length threshold, where the fixed multiple is a positive number less than 1, and specifically, the fixed multiple may be 0.6.

If the second queuing length of the vehicles on the current road section does not exceed the safety length threshold, the congestion degree of the current road section is effectively relieved, and the original time lengths of the current road section, each source road section corresponding to the current road section and the green light of each evacuation road section corresponding to the current road section can support the balance of the traffic in the current road section. Therefore, in the embodiment of the present application, if the second queuing length of the vehicle on the current road section does not exceed the safety length threshold, the time length of the green light of the straight going on the current road section is adjusted to the original time length of the green light of the straight going on the current road section, the time length of the left turn green light of the current road section is adjusted to the original time length of the left turn green light of the current road section, the time length of the green light of each source road section is adjusted to the original time length of the green light of each corresponding source road section, and the time length of the green light of each evacuation road section is adjusted to the original time length of the green light of each corresponding evacuation road section.

If the second queuing length exceeds the safety length threshold, the congestion degree of the current road section is relieved to a certain extent, but the congestion degree is not relieved effectively, and the duration of the green light of the current road section is increased on the basis of the original duration. In addition, in the embodiment of the application, when the congestion degree of the current road section is relieved to a certain extent, the congestion of the current road section can be achieved without increasing too much time on the basis of the original time of the green light of the current road section, so that when the second queuing length exceeds the safety length threshold, the increased green light time of the current road section is shorter than that when the first queuing length exceeds the preset congestion length threshold.

If the second queue length does not exceed the safety length threshold, the green light duration of each evacuation road section of the current road section and the green light duration of each source road section of the current road section may not be adjusted, or the green light duration of each evacuation road section of the current road section may be increased on the basis of the original green light duration of each evacuation road section, and the green light duration of each source road section of the current road section may be decreased on the basis of the original green light duration of each source road section. Specifically, the length of the increasing time and the length of the decreasing time are not limited herein.

In order to accurately adjust the duration of the green light on the current road section, on the basis of the foregoing embodiments, in the embodiment of the present application, the increasing the duration of the green light on the current road section on the basis of the original duration includes:

determining a first ratio corresponding to the green light duration of the current road section according to whether the green light duration of the road section is the original green light duration of the road section; the green time length of the road section is larger than a first ratio corresponding to the non-original time length of the green time length of the road section;

according to the stored first green light duration of the straight-going of the current road section and the stored second green light duration of the left turn of the current road section, determining that a first product of the first green light duration and a preset first ratio is a first target duration increased by the duration of the straight-going green light of the current road section, and determining that a second product of the second green light duration and the first ratio is a second target duration increased by the duration of the left turn of the green light of the current road section;

and increasing the first target time length on the basis of the original time length of the green light of the straight-ahead driving of the current road section, and increasing the second target time length on the basis of the original time length of the left-turning green light of the current road section.

In the embodiment of the present application, the first ratio is a parameter used for determining the target duration, and the corresponding target durations are different because the first ratios used for determining the target duration are different. And when the time length of the green light of the road section is the original time length, the electronic equipment detects whether the road section is jammed, and when the time length of the green light of the road section is not the original time length, the electronic equipment detects whether the jamming degree of the road section is effectively relieved. Therefore, the electronic equipment stores the corresponding relation between the original length of time of the green light of the road section and the specific value and the corresponding relation between the non-original length of time of the green light of the road section and the specific value. When the target duration is determined, determining that the corresponding ratio is the first ratio according to whether the green light duration of the current road section is the original duration.

The first target time length and the second target time length are determined to be longer as the corresponding first ratio is larger when the first target time length and the second target time length are determined. When the road section is jammed, the first target time length increased by the time length of the green light of the straight-going road section on the current road section is longer than the first target time length increased by the time length of the green light of the straight-going road section on the current road section when the jam of the current road section is not effectively relieved; the second target time length increased by the time length of the left turn-to-green light of the current road section when the road section is jammed is longer than the second target time length increased by the time length of the left turn-to-green light of the current road section when the jam of the current road section is not effectively relieved. And the first ratio corresponding to the first target duration may be the same as the first ratio corresponding to the second target duration. Therefore, in the embodiment of the present application, the first ratio of the first target duration to the second target duration is correspondingly determined when the congestion occurs in the current road segment, and is larger than the first ratio of the first target duration to the second target duration when the congestion is not effectively alleviated in the current road segment, that is, the ratio corresponding to the green light duration of the road segment is larger than the ratio corresponding to the non-original green light duration of the road segment.

In the embodiment of the application, after determining the first ratio corresponding to the first target time length and the second target time length, the time length of the increase of the time length of the green light for straight traveling on the current road section and the time length of the increase of the time length of the green light for left turn on the current road section may be determined according to the first ratio, the first time length of straight traveling on the current road section and the second time length of green light for left turn on the current road section. Specifically, the determining process may be: and determining a first product of the first green light time length and a first ratio and a second product of the second green light time length and the first ratio, wherein the first product is a first target time length increased by the time length of the green light of the straight-ahead driving of the current road section, and the second product is a second target time length increased by the time length of the left-turning green light of the current road section. And adding a first product to the time length of the green light of the direct driving of the current road section on the basis of the original time length of the green light of the direct driving of the current road section, and adding a second product to the time length of the left-turning green light of the current road section on the basis of the original time length of the left-turning green light of the current road section.

Taking the example that the duration of the green light on the current road section going straight is 50 seconds, the duration of the left turn green light on the current road section is 20 seconds, and the first ratio is 0.2, the duration increased by the current road section going straight is 50 seconds x 0.2=10 seconds, that is to say, the duration of the green light on the current road section going straight is increased by 10 seconds on the basis of 50 seconds; the time length increased by the left turn of the current road section is 20 seconds x 0.2=4 seconds, namely the time length of the green light of the straight-going current road section is increased by 4 seconds on the basis of 20 seconds.

determining a first ratio corresponding to the green light duration of the current road section according to whether the green light duration of the road section is the original green light duration of the road section; the first ratio corresponding to the original time length of the green light time length of the road section is larger than the first ratio corresponding to the non-original time length of the green light time length of the road section;

acquiring the number of first lanes for straight running and the number of second lanes for left turning of the current road section;

determining a third product of the first green light duration and the first lane number and a fourth product of the second green light duration and the second lane number according to the first green light duration of the straight going of the current road section, the second green light duration of the left turn of the current road section, the first lane number and the second lane number;

acquiring a first sum of the third product and the fourth product, a second sum of the first green light duration and the second green light duration, and determining a second ratio of the first ratio to the first sum, and a fifth product of the second ratio to the second sum; determining that a sixth product of the third product and the fifth product is a first target duration for increasing the duration of green light for straight-ahead driving on the current road section, and a seventh product of the fourth product and the fifth product is a second target duration for increasing the duration of green light for left turn on the current road section;

In the embodiment of the application, after the first ratio corresponding to the target duration is determined, the first target duration increased by the duration of the green light straight running on the current road section and the second target duration increased by the duration of the green light left turning on the current road section can be determined according to the first ratio, the first green light duration straight running on the current road section, the first number of lanes straight running on the current road section, the second green light duration left turning on the current road section and the second number of lanes left turning on the current road section.

Specifically, the determining process may be: determining a third product of the first green light duration and the first lane number, and a fourth product of the second green light duration and the second lane number; after determining a third product and a fourth product, acquiring a first sum of the third product and the fourth product, a second sum of the first green light duration and the second green light duration, determining a second ratio of the first ratio to the first sum, and after determining the second ratio of the first ratio to the first sum, determining a fifth product of the determined second ratio and the second sum; determining a sixth product of the third product and the fifth product as a time length increased by the time length of the green light of the straight-ahead driving of the current road section, and a seventh product of the fourth product and the fifth product as a time length increased by the time length of the left-turn green light of the current road section. And after determining the sixth product and the seventh product, determining that the sixth product is a first target time length increased by the time length of the green light of the straight-ahead driving of the current road section, and determining that the seventh product is a second target time length increased by the time length of the left-turn green light of the current road section. In the embodiment of the present application, the composite lane is treated as a straight lane, that is, if a certain lane is both a straight lane and a left-turn lane, the lane is treated as a straight lane.

Specifically, the determination method may be:

λ＝g*n；
