Embodiment 2

[0097] Such as Figure 5 As shown, different from Embodiment 1, this embodiment also includes:

[0098] The priority vehicle detection step is to detect whether there is a vehicle with priority passing on each lane, and if the detection result is yes, in the calculation step, the passage time of the lane without the priority vehicle is reduced;

[0099] When it is detected that there are priority passing vehicles on multiple lanes at the same time, according to the type of each priority vehicle and the preset vehicle priority level, each priority lane is prioritized. In the calculation step, the highest priority The passing time of other lanes outside the lane is reduced. Between the lanes with the highest priority, according to the preset calculation model, the passing time is allocated according to the vehicle data on each lane.

[0100]In this embodiment, the priority level of priority vehicles is 5, and there are not too many types of vehicles that need to pass through pr...

Embodiment 3

[0105] Such as Figure 6 As shown, different from Embodiment 1, this embodiment also includes:

[0106] The traffic detection step is to detect the traffic situation of vehicles in the traffic lane. As for the specific detection method of vehicle passing, the existing image recognition algorithm can be used, and will not be repeated here.

[0107] In the second control step, when the passing detection step detects that all the vehicles on the passing lane have passed, the traffic lights are controlled to switch to the next lane.

[0108] In this way, after the vehicles in the traffic lane have passed, the second control step controls the traffic lights to switch to the state of passing in the next lane, so that the waiting time of vehicles at the traffic intersection can be effectively reduced, and the traffic efficiency of the traffic intersection can be increased.

Embodiment 4

[0110] Such as Figure 7 As shown, different from Embodiment 1, this embodiment also includes:

[0111] The passing information storage step is to store the passing information of each vehicle.

[0112] The violation detection step is to detect whether the vehicles in each lane pass according to the instructions of the traffic lights. Violations can be detected using existing technologies such as laser scanning or video analysis.

[0113] The violation recording step is to record the information of the vehicle when detecting a vehicle that does not pass according to the instructions of the traffic lights. The specific way of recording is to store the license plate number of the violating vehicle after identifying the license plate number of the violating vehicle by means of photographing and image recognition.

[0114] The violation sending step is to send the recorded information of the violation vehicle to the traffic control department.

[0115] The traffic information ...

Abstract

The invention belongs to the technical field of traffic light control, and particularly provides an intelligent traffic light control method. The method comprises the following steps: a detection step, wherein vehicle data on lanes in various directions is detected, the detection step comprises a first detection step and a second detection step, vehicle information on the lanes in the various directions is acquired through photographing in the first detection step, and images photographed in the first detection step are processed to obtain the vehicle data on the lanes in the various directions in the second detection step; a calculation step, wherein transit time of the lanes is allocated according to a preset calculation model and the vehicle data on the lanes in the various directions;and a control step, wherein traffic lights are controlled according to the time allocated in the calculation step. The method provided by the invention has the advantages that the problems that a large amount of time is wasted on meaningless waiting, road resources are wasted and the traffic congestion situation is worsened can be solved; and meanwhile, as the waiting time of vehicles is shortened, gasoline consumption and exhaust pollution can be reduced.

Description

technical field [0001] The invention belongs to the technical field of traffic light control, in particular to an intelligent traffic light control method. Background technique [0002] With the improvement of living standards, the number of private cars is increasing, and the management of urban traffic is becoming more and more difficult. The traditional traffic light control scheme is to control the traffic lights in each direction according to the fixed timing method, and does not consider the adjustment of the passing time in each direction due to the real-time change of traffic flow. [0003] In real traffic situations, the traffic volume on the lanes in each direction is not always the same. In many cases, the traffic flow of lanes in different directions on the same intersection is quite different. When the lane in direction A is relatively empty and the lane in direction B is relatively congested, according to the traditional traffic light control scheme, all the ...
