Road Traffic Congestion Detection using Active RFID and GSM Technology

The book presents an innovative method of Road Traffic Congestion Detection and Management based on Active RFID and GSM technology . Over the last decade RFID has evolved to become one of the most important and easy solution to many applications. It is being used in nearly each and every field of science and engineering. In this paper we have proposed a solution to traffic congestion detection and management using active RFID. The system developed is known as the TrafficMonitor which calculates two most important traffic parameters viz. average lane speed (average speed of vehicles over a period of time and over a given stretch of lane) and average waiting time. Each vehicle contains an active tag and there are two active readers placed by the road. As the vehicle travels in between these readers, time taken to cover this distance and hence, the speed of the vehicle is calculated. These values are sent to a remote station via SMS (using GSM technology) where data is analyzed and various decisions can be taken based on the received data. For example, travel time information to a particular destination, or average lane speed can be shown to the drivers. This helps daily commuter
