Title: Vehicle traffic control system
Inventor: YAMAGISHI SETSUO
IPC: G08G1/095
Filed: 1989-02-15
Abstract: PURPOSE:To eliminate an entry accident in an intersection by receiving the sent signal of a transmitter and letting a driver of each vehicle know a signal equivalent to the color signal of a traffic light. CONSTITUTION:A radio wave signal device (transmitter) 11 is installed nearby a general blue, yellow, and red type traffic light (color traffic light) 1 and sends signals corresponding to the red signal, yellow signal, and blue signal of the color traffic light 1. Those sent signals are received by a radio wave receiver (receiver) 22 mounted on a vehicle 2 and converted into digital signals, which are sent to an output device 23. The output device 23 decodes the digital signals to judge, for example, the red signal, blue signal, yellow signal, or right (left) turning signal and outputs the signal to the display part in the vehicle together with the reset time to let the driver knows that. Consequently, the driver knows the traffic regulation state in an intersection and makes start or braking preparations to accelerate prevention against an accident.
