Fast passing assisting method and device for vehicles at intersection based on vehicle-road communication

Abstract

The invention relates to a fast passing assisting method and device for vehicles at an intersection based on vehicle-road communication. The method comprises the following steps: 1) arranging the fast passing assisting device for the vehicles at the intersection; 2) acquiring phase timing information of a traffic light through a traffic signal acquiring module, and broadcasting to a vehicle queue waiting in the intersection because of red traffic light; 3) pressing an automatic vehicle control module button by a driver to enable the vehicle to enter an automatic control state; 4) synchronously starting vehicles through automatic vehicle control modules of all vehicle queues waiting because of the red traffic light when the traffic light turns to green; 5) keeping all vehicles at a safe distance under the control of the automatic vehicle control modules so as to form a cruising queue to fast pass through the intersection; 6) pressing an automatic control module button by the driver to finish automatic control and recover the normal driver-based control after passing through the intersection. The method and device can be widely applied to intelligent traffic management processes of various intersections.

Description

technical field [0001] The invention relates to a passing method and device of an intelligent transportation system, in particular to a method and device for assisting rapid passage of vehicles at an intersection based on vehicle-road communication. Background technique [0002] With the growth of car ownership and increasing road traffic volume, problems such as road congestion and frequent traffic accidents are becoming more and more serious. According to the statistics of our country's traffic management department, about 20% of the traffic accidents that occur in our country every year occur at intersections, and at the same time, intersections are also the main road sections of traffic congestion. How to improve the efficiency of vehicles at intersections and ensure driving safety through technical means has become the focus of research by scholars at home and abroad. [0003] In recent years, the emergence of ADAS (Advanced Driving Assistance Systems) based on VIC (Ve...

AI Technical Summary

Problems solved by technology

For example, in the case of a red light, a queue is often formed at the intersection. When the traffic light changes from red to green, the vehicles in the queue will start sequentially and pass through the intersection one after another. However, due to the different driving skills and behaviors of different drivers, The characteristics are different, and the response to the movement state of the vehicle in front is different. There is often a situation that the vehicle in front has driven a certain distance before the vehicle behind starts to start, and even some drivers are not paying attention, so that the vehicle in front has already passed the intersection. The self-vehicle has not yet started, these conditions will seriously affect the efficiency of vehicles at the intersection
