The Research And Design Of The Intelligent Traffic Signal Controller

For the urban "big" development,the ensuing traffic congestion and security issues have seriously affected the harmonious and stable development of society,as well as the general public’s daily life.In recent years,The core philosophy,the key technology and the main content of the intelligent traffic signal control systems,has been constantly improve and enrich with the application of communication,information and control technology in the intelligent traffic management and control.The application and research create good social benefit and economic benifit for the urban road traffic signal control effect and people’s travel environment,are of great significance.In this paper,we mainly study the through multi bus system model architecture and modularized design mode to improve product reliability,stability and maintainability,using hardware sccess layer,control layer and the data exchange layer three layer embedded software architecture model enhanced software system running stability,and approach,a full range enhance the operation satety of the products,to ensure the normal operation of the intersection traffic signal,to protect the safety of people traveling.In addition,a single road traffic signal control machine is realized to control the function of the trafic signal at the same time,and can be upgraded to a regional coordinated control host machine.At the same time,networking of detection and recognition technology based on,combined with corresponding priority control algorithm to realize the bus signal priority control,enhances the product of intelligent,effectively relieve traffic congestion,improve people’s travel environment,reduce the pollution of the environment.
