A SMART TRAFFIC SIGNAL TRAPPING SYSTEM

Abstract

A Smart traffic control system is presented to pass emergency vehicles smoothly. Each individual vehicle is connected with a special radio frequency identification (RFID) tag (placed in a strategic location), which makes nobody can remove or destroy the unit placed. Here RFID reader, NSK EDK-125–TTL, and PIC16F877A system-on-chip to read the RFID tags which is attached to the movable unit. The RFID is used to count the number of vehicles that passes on a particular path during a specified duration. It determines the network congestion and hence the green light duration for that path is enabled or disabled. If the RFID-tag-read belongs to the stolen vehicle, then intimation is sent using GSM SIM300 to the police control room. In addition to that an ambulance arriving towards to the junction, it will communicate with the traffic controller in the junction to turn ON the blue light. This module uses ZigBee modules on CC2500 and PIC16F877A system-on-chip for wireless communications between the ambulance and traffic controller.
