Abstract

The invention discloses a wireless traffic signal control system, implementing the control of a traffic signal controller on a counting-down board in a wireless transmitting mode, and particularly making real-time self-adapting control according to the traffic flow signal of each crossing. The invention constructs a traffic signal control system in a wireless accessing mode, and can set several crossings as a traffic signal control system, even some region or city as a traffic signal control system, thus reducing the cost and able to orderly, and systemically control the traffic at each crossing. Besides, the invention solves the problem that the exiting self-adapting traffic signal control system is unable to control the counting-down board in time, and implements the function of controlling the counting-down board, wirelessly.

Description

technical field

[0001] The present invention relates to a traffic control system, in particular to a traffic signal control system. Background technique

[0002] With the gradual advancement of urban construction and the continuous increase in the number of motor vehicles, the problem of urban traffic congestion is also becoming more and more serious. Especially in the traffic peak period, various motor vehicles and non-motor vehicles compete with each other at intersections and easily cause various traffic accidents. This is a big problem in urban traffic that needs to be solved. In addition to the need to improve traffic awareness of drivers and pedestrians, there is also a need to improve the ability to control traffic lights at intersections.

[0003] The existing traffic signal control system is usually a digital display traffic signal control system. This control system generally uses the power line of each signal light to be connected to the cable embedded in the und...
