Design of an Intelligent Auto Traffic Signal Controller with Emergency Override

The main objective of this project is to design an intelligent auto traffic signal control system. Traffic congestion is one of the major issues to be considered.Generally Vehicular traffic intersects at the junctions of the road and are controlled by the traffic signals.Traffic signals need a good coordination and control to ensure the smooth and safe flow of the vehicular traffic.During the rush hours, the traffic on the roads is at its peak. Also, there is a possibility for the emergency vehicles to stuck in the traffic jam.Therefore; there is a need for the dynamic control of the traffic during rush hours. Hence,I propose a smart traffic signal controller.The proposed system tries to minimize the possibilities of traffic jams, caused by the traffic lights, to some extent by clearing the road with higher density of vehicles and also provides the clearance for the emergency vehicle if any. The system is based on the PIC 16F877A micro controller, IR sensors and Radio Frequency Identification (RFID) technology. The code for this project is compiled in high tech C compiler and the simulated with Proteus software.
