Introduction

ATC systems are intelligent real-time dynamic traffic control systems which are designed to effectively respond to rapid variations in dynamic traffic conditions. It is an advanced process to control the traffic. It is a traffic responsive system that use data from vehicle detectors and optimize traffic signal time in real time. The timing plan of traffic controllers changed automatically. The technique employs digital computers for achieving the desired objective.
