AN APPARATUS AND METHOD FOR ROAD ACCIDENT RISK REDUCTION

摘要

The present invention provides a method for monitoring and detecting vehicles at risk of a car accident in a high-risk accident area. The method comprises fusing a motion sensing device on the surface of a road in one moving direction at the high risk- area, wherein the motion sensing device comprising four detection bars operable to detect a passing vehicle based light intensity change detected through the detection bars; acquiring timing information of the passing vehicle passing through each of the four detection bar of the motion-sensing device to interpret velocities and accelerations of the passing vehicle; determining a potential road-accident hazard based on the interpreted velocities and accelerations of the moving vehicle; providing a warning signal for an opposing moving direction when the potential road-accident hazard is determined; and storing the timing information acquired and interpreted in a database of a microcontroller of the motion sensing device.
