Abstract
A traffic warning system which alerts approaching vehicle traffic to the presence of a pedestrian in a crosswalk. The system includes a plurality of surface mounted lights partially embedded in and placed across a roadway. The lights are activated by the pedestrian, either by manual switch or by a sensor, before he enters the crosswalk. Once activated, the flashing lights warn drivers of approaching vehicles that the pedestrian may have entered the crosswalk, and that caution should be exercised.
