Safe and efficient traffic signal light management system and method

Abstract

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.

Description

technical field [0001] The invention relates to a safe and efficient traffic signal light management system and method. The system applies single-chip processing technology and modern sensing technology to realize the safety and high efficiency of pedestrians crossing road zebra crossings. It is suitable for zebra crossings on inter-city main roads, can also be used for zebra crossings on inner-city roads, and can also be used at intersections of main roads and secondary arterial roads. Background technique [0002] With the rapid development of society and the advancement of urbanization, as a developing country with the fastest development and huge volume, China has conducted long-term exploration and research in urban planning. People's increasing dependence on transportation and the drive of economic interests have brought about the improvement of the transportation system. In recent years, the improvement and research on the urban road system have emerged one after anot...

Problems solved by technology

After on-the-spot investigation, we found the obvious problems: 1. The traffic efficiency is low. There are relatively few pedestrians crossing the road on the secondary trunk road and the branch road. , delays time, does not meet the requirements of "fast and efficient city", and at the same time, unnecessary deceleration accelerates the wear and tear of motor vehicles and the emission of pollutants
