Abstract
This invention provides a pedestrian signal system not only for normal pedestrians but also for the blind, the disabled person of weak sight, and the illiterate by displaying the remaining time of each signal change in image figures at the signal head and by generating a voice signal in real time. It reduces the cost of the system fabrication, installation and maintenance of the system by combining the five functions of the pedestrian signals such as a walk signal, a stop signal, a remaining time of each signal of red/green and/or the voice generator for blinds in one signal head. Also, this invention provides the useful double safety traffic signal system especially for a school zone by installing LED studs on the stop line at crossroad for warning drivers by blinking the LED studs automatically when the walk signal is in on-mode.
