Design Of Semi-Automatic Traffic Light Control System

AbstractTodays traffic light system has a lot of limitations at road junction. The system is not flexible or in other words cannot modify on real time . The static traffic control have fixed timing for the three traffic lights the green yellow and red .The cars waste a lot of fuel and surely the driver waste a lot of time . To solve and monitor the traffic light system and make it more efficient we have to use an intelligent technique taking the advantage of the sensors microcontroller and the GSM modem which could add the real time benefit to the system. This paper explores the design of semi automatic traffic light control system. The traffic light is designed using microcontroller ATMEGA32 programmed by BASCOM AVR power supply IR sensor and GSM modem . The system solves the wasting time and fuel problem and the problem of the emergency car which waits a lot in the road intersection as well as it solves the problem of the congestion that occurs when an accident in the path happens. The system can be used for the traffic at the road intersections.
