ABSTRACT:
The present invention relates to a traffic signaling device comprising a plurality of light bars which can be sequentially controlled and switched on/off to provide a dynamic signal to the drivers and pedestrians. The color of the light bars can turn red to indicate a stop signal or green to allow the traffic to proceed. The light bars can be switched off in a sequence to advise the drivers and the pedestrians as how much time is left before one color is replaced by another color. With this arrangement, the drivers and the pedestrians can adjust their pace when they are passing a crossroad. Preferably, the top portion of each of the signaling devices is shaped to show the traffic directions. For example, the top portion can be shaped to indicate left-turning, right-turning, straight forward, etc. Moreover, the bottom of the signaling device can he also attached with a road sign to assist a driver to find his or her way.
