Vehicular access cooperative system with function of emergency collision avoidance early warning for red light running and method

Abstract

The invention provides a vehicular access cooperative system with a function of emergency collision avoidance early warning for red light running and a method. The vehicular access cooperative system comprises an intersection controller, a vehicle-mounted controller for vehicles at a red light phase position, and a vehicle-mounted controller for vehicles at a green light phase position. The intersection controller is used for collecting signal light information and a stop line position information for the red light phase position, and transmitting the collected information to the vehicles at the red light phase position when a traffic light is red. When an action of running the red light happens, the intersection controller can transmit early warning information to the vehicles at the green light phase position. The vehicle-mounted controller for the vehicles at the red light phase position is used for obtaining position information and speed information of the vehicles at the red light phase position, and receiving and processing the collected information. The vehicle-mounted controller for the vehicles at the green light phase position is used for receiving the early warning information. Through signal transmission between the intersection controller and the vehicle-mounted controllers, and by means of a vehicle early warning module to judge whether the vehicles at the red light phase position run the red light, and when the action of running the red light happens, the vehicular access cooperative system can transmit the early warning information to the vehicles at the green light phase position, so the vehicular access cooperative system reduces occurrence of vehicle collision accidents due to the fact that the vehicles at an interjection run the red light.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a vehicle-road coordination system and method with an emergency collision avoidance warning function for running a red light. Background technique [0002] At a signal-controlled intersection, when a driver tries to pass through the intersection during the green light time, a red-light vehicle turning left or going straight from other directions at the intersection is very likely to collide with a normal passing vehicle. The severity of the collision accidents caused is relatively high, so the life threat brought by the red light vehicle to others cannot be ignored. How to reduce the threat that the red light vehicle brings to other vehicles has become a difficult problem to be solved. [0003] At present, the development of vehicle-road coordination technology has provided ideas and methods for solving the problem of red-light collision accidents. The red-light emergency ...

Problems solved by technology

[0004] Due to the greater harm caused by collisions, emergency collision avoidance and early warning technology has been the focus of research by many scholars at home and abroad. However, there are relatively few studies on collisions caused by vehicles running red lights at intersections.
