    摘要: A system, program product and method for automatically adjusting the traffic light of a traffic light controlled intersection. Personal data relative to a pedestrian cross walking the intersection, including walking speed, and the current speed of a vehicle approaching the intersection are simultaneously acquired. Both the personal data and the vehicle current speed are processed to generate cross walk control signals, such as indicators of risk of collision between vehicle and pedestrian. Where the risk warrants action, the “stop” condition of the traffic light is enable to warn the vehicle to stop. Traffic control signals are also generated to control the duration of the “walk” condition for slow moving pedestrians.
