WSN Based Traffic Control System for Congestion Control for Ambulance Clearance, and Stolen Vehicle Detection

Abstract

This project represents an intelligent traffic control system to run emergency vehicles smoothly. Each individual vehicle is equipped with unique radio frequency identification tag (placed at a strategic location),this is impossible to remove or destroy. We use RFID reader, and LPC2148 system-on-chip to read the RFID tags attached to the vehicle. RFID counts the number of vehicles that are passed on the particular way during a specific duration. It also determines the network congestion, and then the green light is on for some duration for that path. If the RFID-tag-read belongs to the stolen vehicle, then a message is sent using GSM SIM900 to the police control room and to the owner of the vehicle. In addition, when an ambulance is coming to that particular junction, RFID will communicate the information to the traffic controller in the junction to turn ON the green light. This module uses ZigBeetechnology on CC2500 and LPC2148 system-on-chip for communications between the ambulance and traffic controller. The prototype was observed under different combinations of inputs in our wireless communication laboratory and experimental results were accurate.
