260 results about "Red light running" patented technology

Red light running defined. If a vehicle enters an intersection any time after the signal light has turned red, the driver has committed a violation. Motorists who are inadvertently in an intersection when the signal changes (waiting to turn left, for example) are not red light runners.

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

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.
