Green wave passing method and device

Abstract

The embodiment of the invention provides a green wave passing method and device, and the method is applied to an edge server, and comprises the steps: obtaining traffic light state information and traffic light position information determined by a road side unit, wherein the traffic light position information carries a road side unit identifier; receiving a traffic light adjustment request sent bythe vehicle-mounted unit, wherein the traffic light adjustment request carries a target road side unit identifier; determining a target road side unit corresponding to the target road side unit identifier; generating an adjustment message according to the traffic light state information of the target road side unit; sending the adjustment message to the target road side unit, wherein the target road side unit is used for adjusting the traffic light state information according to the adjustment message. Therefore, vehicles can quickly and safely pass through the intersection, the passing efficiency is improved, and continuous green wave passing at multiple intersections is achieved.

Description

technical field [0001] The invention relates to the technical field of traffic signal control, in particular to a green wave passing method and a green wave passing device. Background technique [0002] At present, in the crossroads of urban roads, in order to pass safely, traffic lights are generally used to control the passage of vehicles and pedestrians. Among them, the traffic signal light is a signal light for directing traffic operation, and generally consists of red light, green light and yellow light. A red light means no access, a green light means permission to pass, and a yellow light means a warning. [0003] During vehicle driving, the following four scenarios are usually encountered: [0004] Scenario 1: The vehicle is 300m away from the intersection, and the current speed is 80km / h. At this time, it is in a red light state, and the countdown device does not display the time (by default, the countdown will only be displayed within the remaining 15s), and the ...

AI Technical Summary

Problems solved by technology

[0014] 1) Vehicles and traffic lights do not have a perception coordination system, and the status information of traffic lights cannot be read, and the vehicle does not have the function of adjusting and controlling the status of traffic lights

[0015] 2) When the vehicle passes through the intersection, the driver cannot make an accurate judgment on the status and changes of the traffic lights in a short period of time, and it is easy to misjudge and cause traffic accidents

[0016] 3) The traffic light control time is periodic, and the state of the light cannot be changed according to the distance of the detected vehicle to the intersection. The traffic efficiency of the intersection controlled by the signal light is not high, and it is easy to increase traffic congestion
