Problems solved by technology

Now the traffic extends in all directions, there are often multiple intersections on a road, and traffic lights are installed at each intersection, which makes the efficiency of traffic very low
At present, the layout of traffic lights at multiple intersections on a road is to calculate the opening time of the front and rear green lights according to the length of the road and the speed of the car, so that the car enters the first green light and passes through the approved speed to the second intersection as a green light. And so on, this arrangement mode i

Example Embodiment

[0023] Example 1:

[0024] Such as figure 1 As shown, a multi-intersection traffic signal light optimization control system includes a traffic signal light installed at an intersection, a control system, and a sensor connected to each lane, and the sensor is generally a ground-induction coil installed in each lane , The traffic signal lights are installed in all directions of the intersection, and each traffic signal light is controlled by the control system.

[0025] Control system communication connection (wired or wireless) cloud server. The cloud server divides urban roads or roads in a certain area into main arterial roads and secondary arterial roads according to the traffic volume, and sets the straight and right turn signal lights of main roads to evergreen active State, that is, when the main road is not triggered, the straight and right turn signal lights of the main road are always green (passable), the left turn of the main road and all the signal lights of the secondar...

Example Embodiment

[0027] Example 2:

[0028] Such as figure 2 As shown, the optimized control system of this embodiment adopts the optimized control system of embodiment 1. The difference is that the control system can also be connected to an image acquisition device, such as a camera. The image acquisition device is used to collect images of vehicles on each lane. The image acquisition device is connected to the processing module, and the processing module is used to process the vehicle images of each lane to generate the number of vehicles waiting for each lane or the vehicle waiting time.

[0029] Such as image 3 As shown, a method for optimal control of traffic signal lights at multiple intersections of the present invention includes the following steps:

[0030] S01: Divide the road into main roads and secondary roads according to the traffic volume;

[0031] S02: Set the straight and right turn signal lights of the main road to the evergreen active state, and the left turn of the main road and...

Abstract

The invention discloses a multi-intersection traffic signal light optimal control system. The system comprises traffic signal lights installed at an intersection, a control system, and an inductor connected with the control system and arranged at each lane; the system further comprises a cloud server in communication connection with the control system, wherein the cloud server is used for dividing a road into a trunk road and a secondary trunk road according to traffic flow, a straight signal light and a right turn signal light arranged on the trunk road are in an ever-green active state, a left-turn signal light of the trunk road and all signal lights of the secondary trunk road are in an ever-red passive state; the ever-green active state and the ever-red passive state are triggered to change by a threshold value of each lane; when the ever-green active state and/or the ever-red passive state are/is triggered to change, the control system is in linkage work according to a preset control signal light. The system disclosed by the invention is simple in implementation, low in improvement cost, capable of controlling the traffic signal lights at multiple intersections, guaranteeing the traffic smoothness of the trunk road, improving the comprehensive capacity of the trunk road and the secondary trunk road, and reducing the waiting, protecting environment and saving energy.

Description

technical field [0001] The invention relates to a method and system for optimal control of traffic signal lamps, in particular to a method and system for optimal control of traffic signal lamps at multiple intersections. Background technique [0002] The optimal control of traffic lights can reduce the waiting congestion of cars, reduce vehicle exhaust emissions, reduce energy consumption, and be environmentally friendly and energy-saving. Traffic extends in all directions now, and a road often has a plurality of crossings, and traffic lights are installed at each crossing, so that the efficiency of passing is very low. At present, the layout of traffic lights at multiple intersections on a road is to calculate the opening time of the front and rear green lights according to the length of the road and the speed of the car, so that the car enters the first green light and passes through the approved speed to the second intersection as a green light. By analogy, such an arran...
