As the population grows and the number of cars on the road decreases, it is reasonable to expect that the number of site visitors will increase, making manual control more difficult. Site visitors' police officers will benefit from this project, which is aimed at creating a cloud-based interface between motors so that traffic may be tracked automatically. The regulation of traffic lights on the road crossing has to be done on basis of traffic congestion and it is measured through the ultrasonic sensors. At road crossing four routes are making junction and on each route three sensors are connected to measure three levels of congestion i-e low, medium and high. Different technologies are there to detect traffic congestion and making congestion management more efficient. But these technologies have several drawbacks. RFID is easier, efficient and inexpensive congestion detection technology. Using RFID, we emerge new technique called as “Controller Based Intelligent Traffic Control System”. This uses sensors along with embedded technology. It has facility to control timings of the red and green lights based on the traffic, pass the emergency vehicles such as ambulance, fire brigade etc.
