Pedestrian Safety and Early Warning System Based on Green Energy

Abstract

In Taiwan, pedestrians are run over by vehicles often in many intersectionsdue to poor lighting or lack of traffic lights. Thus, we developed a green energy-driven automatic warning system to ensure the safety of drivers and pedestrians. A variety of sensing modules, such as Hall sensors and coil loops, were used in the system to detect approachingvehicles. When an approaching vehicle was detected, the LED warning light warned pedestrians and drivers. In addition, according to data released by the government, sensors or detectors were set up at a sufficient distance from the crosswalk to ensure that the vehicle could stop before it reached the sidewalk. In the system, green energy was used to ensure that the entire system was operated for a long time and reduced energy consumption. It was verified that the proposed system could be used in various environments such as suburbs or remote intersections to improve safety.
