Traffic control system using multiple yellow lights to divide a cautionary signal into equal parts

摘要

A traffic control system for controlling vehicular traffic flow at intersections in which the conventional red/yellow/green three-light traffic signal that informs a motorist to stop, prepare to stop, and go is supplemented with multiple yellow light signals which are integrated as part of the traffic light. The additional yellow light signals inform a motorist that they will have sufficient time to make a gradual normal stop at the intersection before the red stop light is switched on by dividing the duration of the yellow cautionary signal into multiple yellow light signals.
