Traffic signal light system and method capable of automatically regulating duration of traffic signal lights

Abstract

The invention discloses a traffic signal light system and a method capable of automatically regulating duration of traffic signal lights, and relates to the field of intelligent traffic. The traffic signal light system is characterized in that a traffic flow information unit (50) and a GPS (Global Positioning System) navigation data service unit (60) are respectively communicated with a network communication unit (40); the network communication unit (40), a traffic management center control unit (30), a signal light control unit (10) and traffic signal lights (70) are communicated in sequence; a GPS unit (20) is communicated with the signal light control unit (10). According to the traffic signal light system and the method, disclosed by the invention, GPS navigation user data are adopted, intersection traffic flow information can be automatically extracted according to intersection space geographical position information, the queuing length of vehicles in all directions of an intersection can be calculated, and linked and coordinated setting on duration of red light for stop and green light for go in each intersection can be realized, so that intersection road resources can be reasonably distributed, the intersection traffic efficiency is increased, an intersection congestion problem is effectively solved, and the labor cost for maintaining the traffic order is saved.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a traffic signal light system and a method for automatically adjusting the duration of traffic lights. Background technique [0002] In order to solve the problem of urban traffic congestion, traffic congestion cannot be alleviated only by improving the road network; what is urgently needed at present is to further tap the potential of the road network and improve the traffic situation, especially to improve the control of traffic signals. It can be seen that it is necessary to develop an efficient intelligent traffic control system. Therefore, the intelligent control of urban traffic has become one of the research hotspots in the field of traffic engineering at home and abroad. The intersection is the throat of the urban road network, where people and vehicles gather, and traffic jams are most likely to occur. Therefore, the intelligent control of intersection signals ...
