Embedded Technologies RFID GSM and GPS for Traffic Controller

Intelligent traffic control systems are advanced applications which, without embodying intelligence as such, aim to provide innovative services relating to different modes of transport and traffic management and enable various users to be better informed and make safer, more coordinated, and 'smarter' use of transport networks. In this project, I attempt to make an intelligent system which helps in congestion control, ambulance clearance and stolen vehicle detection which solves the road safety problems to a greater extend. Each individual vehicle is equipped with special radio frequency identification (RFID) tag. We use RFID readers along with microcontrollers to read the tags attached to each vehicle. It counts the number of vehicles that pass through the path during a specific duration, so that network congestion is determined and hence green light duration for a particular path. If RFID tag belongs to the stolen vehicle, it is informed to the police control room through GSM. In addition if the ambulance is approaching the junction, it will communicate to the traffic controller on the junction to turn the green light on. This module uses ZIGBEE and PIC microcontroller for wireless communication between ambulance and the traffic controller.
