摘要：Effective reduction of the road traffic in the real time phase is very essential. The present infrastructure available for the road traffic is not adequate, due to steady increase in the number of vehicles per day. The automated signals need more dynamism. This paper endeavors to provide solutio n to such a situation. The methodologies and technologies vary from inductive loop detection, video data analysis, passive infrared sensors and wireless sensor network. These available technologies are costly and complex. Radio frequency identification (RFID) is an easier, efficient and inexpensive technology which can be deployed for such heavy traffic situation. RFID tags, routers and coordinators could be used with the CRTO (Coordinated Router Traffic Optimization) algorithm. These RFID tags fixed in the vehicles could be read by the routers and coordinators fixed on the road sides. Regular distance could be maintained between one set of coordinators and the routers. The vehicles which are plying on such roads will be sensed by the signal and read by the routers and then by the coordinators. The speed of the vehicle is calculated by the time taken to reach the coordinator after crossing the router. Based on the number of vehicles nearing the signal and the speed of the vehicles, the coordinators are allowed to communicate and the signals are controlled by the coordinators. Traffic is controlled taking these parameters into consideratio n.
