Traffic Light Controller System for Emergency Vehicles Priority: A Review

This study aims to explore the integration of RFID technology and inductive loop sensors to improve traffic flow and minimize congestion at a four-way junction, particularly for emergency vehicles, while minimizing congestion. While existing research thoroughly investigates RFID's role in vehicle identification and the effectiveness of inductive loop sensors for vehicle detection, limited attention has been given to their integration. This study aims to fill this gap by developing an integrated system that utilizes RFID for prioritizing emergency vehicles and inductive loops for real-time vehicle detection and classification at traffic lights. The findings highlight the potential of RFID and inductive loop sensors offers a promising solution for more efficient traffic management and a better emergency vehicle prioritization, contributing to the development of smarter, responsive urban traffic control systems.
