Vehicular access cooperative system with early warning prompting function for red light running and method

Abstract

The invention provides a vehicular access cooperative system with an early warning prompting function for red light running and a method. The vehicular access cooperative system comprises an intersection controller, a vehicle-mounted controller and a voice prompter. The intersection controller is used for collecting signal light information and stop line position information of the vehicle driving direction, and transmitting the collected information to the vehicle-mounted controller. The vehicle-mounted controller is used for obtaining position information of vehicles, speed information of the vehicles, receiving the collected information transmitted by the intersection controller, and processing the obtained information and the collected information. The voice prompter is used for carrying out voice prompt to drivers. Due to the fact that the intersection controller transmits the signal light information of the vehicle driving direction and global position system (GPS) information of the vehicle driving direction to the vehicle-mounted controller, and an early warning and decision-making module is utilized to give out aid decision-making information that whether a driver can pass through an intersection and whether the driver needs to slow down and brake, and transfer the information to the driver in a voice prompt mode, the vehicular access cooperative system avoids the occurrence of the action that the driver mistakenly runs the red light when a traffic light is yellow, and reduces traffic accident rate.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a vehicle-road cooperative early warning system and method with a red light running warning function. Background technique [0002] At present, the phenomenon of running red lights at road intersections often occurs. Traditional signal control methods have certain limitations in reducing the behavior of running red lights. Especially at the time of yellow lights, there is no fixed and unified standard for drivers to "go" or "stop". Drivers can only choose "go" or "stop" according to their own experience. Usually, when drivers encounter a yellow light, if they are far away from the intersection, most of them will choose to stop. If they are relatively close to the intersection, they will choose to stop. Select pass. However, the driver may be "not far or near" from the intersection when encountering a yellow light. In addition, due to differences in driving experience and...

AI Technical Summary

Problems solved by technology

The early warning technology based on vehicle-road coordination is to judge whether the vehicle can pass the intersection within the yellow light time by analyzing key parameters such as the speed, position, and yellow light time of the driving vehicle. If it cannot pass safely, it will pass the early warning in the vehicle. The device provides the driver with early warning information such as attention to deceleration, so as to prevent the driver from running a red light unintentionally. This technology has strong practicability and high accuracy, but the technical cost is high. It needs the assistance of communication, computer and other fields. It is currently in the research stage.
