Embodiment 1

[0039] Embodiment 1, a traffic signal light intelligent control method provided by the present invention is applied to a traffic signal light intelligent control system. The system is based on DSRC technology and includes a vehicle-mounted terminal installed on the vehicle, a roadside device wirelessly connected to the vehicle-mounted terminal, and a traffic signal light controlled by the roadside device. As shown in Figure 1, the control methods include:

[0040] S101: The roadside equipment receives the passing information of the vehicles in the target passing intersection, wherein the passing information is acquired and sent by the vehicle-mounted terminal installed on each of the vehicles;

[0041] When the vehicle passes the intersection, the vehicle-mounted terminal installed on the vehicle continuously broadcasts its own traffic information, which conveys the sender's core status information, that is, the vehicle's position information and direction information, and the...

Embodiment 2

[0046] Embodiment 2. On the basis of Embodiment 1, while controlling the traffic lights, the roadside device can also send the traffic strategy to the vehicle in the target intersection, and the vehicle-mounted The terminal receives and plays. Vehicles passing through the intersection can obtain the signal light status and countdown information of the intersection in advance, and display them on the on-board display unit, so that the driver can receive the signal light status and countdown information in real time, avoiding the situation of poor vision in heavy fog and rainy days The traffic light information is not accurate enough to occur.

[0047] Furthermore, the roadside equipment will calculate the traffic flow based on the vehicle traffic information obtained at intersections in all directions. It can be understood that when special vehicles such as ambulances and fire trucks need to pass first, emergency vehicle passage messages are continuously sent to the surroundin...

Embodiment 3

[0049] Embodiment 3, on the basis of the above embodiments, the location information and the direction information are acquired by the satellite positioning module of the vehicle-mounted terminal, the position information includes latitude and longitude information, and the direction information is obtained by the vehicle-mounted terminal Install the included angle between the driving direction of the vehicle and the true north direction; wherein the satellite positioning module can be GPS, Beidou and other modules.

[0050] Then the step of determining the traffic strategy of the target traffic intersection according to the traffic information is specifically:

[0051] The roadside equipment determines the incoming vehicle direction according to the angle between the driving direction of the vehicle installed on each vehicle-mounted terminal and the true north direction, and determines the traffic strategy in combination with the road setting conditions of the target traffic int...

Abstract

An intelligent control method for a traffic signal light, comprising: a roadside equipment receiving passing information of vehicles in a target passing intersection, the passing information being obtained and sent by a vehicle-mounted terminal which is arranged on each vehicle (101); determining a passing strategy of the target passing intersection according to the passing information (102); and controlling a traffic signal light in the target passing intersection according to the passing strategy (103). Also disclosed are a roadside equipment and a control system, which may effectively sense a passing state of a vehicle at an intersection, and may change a running strategy in a timely manner so as to achieve safe and efficient passing. At the same time, the method may be quickly applied to different intersection conditions.

Description

technical field [0001] The present application relates to the field of intelligent transportation, in particular to an intelligent control method for traffic signal lights, roadside equipment and a system. Background technique [0002] With the rapid development of my country's economy and the continuous advancement of urbanization, the number of cars has increased rapidly, and traffic safety and congestion problems have become increasingly prominent problems. Traditional solutions have defects such as incomplete information detection and insufficient sharing, making the current situation still Not optimistic. The intersection of urban roads is the key point of the entire traffic network. It connects roads in different directions and is a transit point for vehicles and people in all directions. Due to these characteristics of road intersections, the intersections are extremely prone to congestion, and become the bottleneck of urban traffic capacity and the frequent occurrenc...
