Brief introduction of traffic signal control hardware equipment

Traffic signal control is to use traffic signals to direct and guide vehicles and pedestrians running on the road.


The so-called traffic signal refers to the legally effective information that the traffic management department sends to vehicles and pedestrians to pass, stop or stop on the road according to the relevant national laws and regulations. Traffic signal automatic control is an important part of scientific traffic management. Modern traffic signal control system has the following functions: improve the traffic efficiency of existing roads; Improving road traffic safety; Reduce energy consumption and environmental pollution; Collect traffic information and provide traffic intelligence; Strengthen traffic law enforcement and traffic guidance to provide comprehensive economic benefits for the whole society. Facts have proved that modern traffic control is one of the important measures to alleviate urban traffic problems.


The composition of traffic signal hardware equipment mainly includes the following 6 parts:


1. Traffic lights:


It is a light-emitting device suspended over the road or set on the roadside lamp post, which is equipped with color signal lights;


2. Vehicle detector:


When the vehicle passes through the detector, the facility that can detect traffic parameters according to the induction principle is a necessary facility of the inductive signal control system;


3. Wireless remote control device:


Turn on and off traffic lights to control the red light when emergency vehicles pass;


4. Electronic police (camera):


Monitor illegal vehicles;


5. Single chip microcomputer system:


The core of the whole signal light control;


6. Ancillary facilities:


It includes traffic signal lamp pole, lamp post and its foundation, base and foundation of signal controller, pipeline and pole for embedding or hanging transmission line, etc.
