The invention discloses a safe and efficient
traffic signal light management system and method. The
system is provided with two
infrared sensing modules which are arranged in the direction that pedestrians walk towards a
zebra crossing in sequence, and the walking direction of the pedestrians can be judged according to the triggered sequence of the
infrared sensing modules; if the
far infrared sensing module is firstly triggered and the near
infrared sensing module is triggered later, it shows that the pedestrians walk towards the
zebra crossing, the behavior is valid, when the behavior is valid, traffic lights on a road and traffic lights for the pedestrians are changed, the light colors are changed, and the management of the traffic lights is achieved; if the near infrared sensing moduleis firstly triggered and the
far infrared sensing module is triggered later, it shows that the pedestrians walk back on to the
zebra crossing, and the behavior is invalid; the behaviors of the pedestrians are effectively identified, and invalid triggering is avoided. Besides, through the combination of a pressure-sensitive sensor, double insurance is achieved; the
pedestrian behaviors are furthereffectively identified and invalid triggering is avoided (if the pedestrians just want to go to a crossing to look around instead of crossing the road, the pressure-sensitive sensor cannot be triggered) while the
traffic efficiency is guaranteed. The safe and efficient
traffic signal light management system improves the safety and the user-friendliness.
