RED LIGHT VIOLATION MONITORING AND REPORTING USING MICROCONTROLLER CONTROLLED WIRELESS COMMUNICATION

Abstract

Traffic accidents are now one of the main causes of death and economic loss in most of the developed

countries. Noncompliance with traffic laws is severely impeding the safety of the road traffic system. In this

paper a system for monitoring and reporting incidences of red light violations at the traffic intersection has

been proposed. A prototype of the system was build and verified experimentally. The system comprises an

infrared (IR) transmitter and receiver unit for detection of red light violation whereas for identifying the

vehicle, microcontroller triggered wireless mobile network has been used. The microcontroller was

programmed to automatically send message containing the car license no, date and time of breaking the rule

to the numbers of traffic control units stored previously to the cell phone directory. Upon detection of the

offender, the corresponding action can be performed by the traffic monitoring system. The proposed system

is simple, cheap, reliable, and exempted from the effects of bad weather conditions, improper lightings etc.

and thus more suitable for detection of a violation and identification of the vehicle involved.
