Real time traffic congestion detection and management using Active RFID and GSM technology

-Use of existing popular technologies for traffic congestion detection and management has been explored by several researchers in recent times. However, most of the works either deal with congestion detection strategies or address the issue of congestion control through signal manipulation or other aids. To the best of our knowledge, no effort has been made so far to develop a comprehensive system that automatically detects as well as controls traffic congestion based on detected level of congestion. The aim of this paper is to design a complete strategy for automatic road traffic congestion detection in realtime and to devise an effective scheme for control/ management of congestion using Active RFID and GSM technology. In this paper, we discussed some of the most widely adopted technologies for congestion detection and management, their limitations. Finally, we described the outline of our Active RFID based congestion detection and management scheme to overcome the existing problems. Further, we have illustrated a simulation model that we have developed to generate different traffic congestion scenarios, to implement and test our scheme for congestion detection and management.
