This document describes an RFID-based traffic control system using GSM. The major components of the system include a power supply, microcontroller, RFID tags and readers, and a GSM modem. RFID tags are attached to vehicles. When a vehicle passes an RFID reader near a traffic signal, the vehicle's information is sent via GSM modem to a control room. This system aims to help manage traffic and detect violations. Potential applications include congestion monitoring, intelligent traffic lights, and public parking management.
