Alarm Crosswalk2009-11-19 13:22 - 0 Comments
The idea is to avoid people crossing the walks on red lights. Too many people cross the crosswalks on redlights when there are not cars. My idea consist on installing a sensor on the floor on each site of crosswalk that will detect when people put a foot on the crosswalk and it is red light. If someone crosses the street, a speaker will make a sound and a light on the opposite site of the crosswalk will flash the pedestrian so he/she will realize that is not allowed to cross on red light.
