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.
