DESIGN AND CONSTRUCTION OF MICROCONTROLLER BASED INTELLIGENT TRAFFIC LIGHT CONTROLLER

ABSTRACT:

 A traffic light system is an electronic circuitry designed and configured to control the flow of the traffic (vehicular and

human) at roads intersection without the physical presence of a traffic warden. This is made possible through the help of a signaling device which is mounted at roads intersection. It is achieved using electronic components and a

micro-controller for proper timing and execution.
