Embodiment Construction

[0105] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0106] One of the core ideas of the embodiment of the present invention is to read the traffic light status information of the traffic light signal machine in real time through the RSU (Road Side Unit) of multiple intersection devices, and report it to the edge server MEC, and download it in real time through the MEC. Send to the surrounding device OBU (On Board Unit, on-board unit) the traffic light status information of the vehicle interactive intersection. The OBU can comprehensively calculate and judge in real time based on the distance from the vehicle to the intersection, the remaining time of the traffic light, and the current speed of the vehicle. Whether it is necessary to wait when passing the intersection During the red ...

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 ...
