RFID based Smart Traffic System for Emergency Vehicles

Abstract

The traffic congestion problem is an issue that has had a significant influence on the country's transportation system. This creates a slew of issues particularly when there are emergencies at traffic signal junctions, which are constantly congested. These issues are addressed by a traffic light control system. This system was created to run when it received a signal from an emergency vehicle through radio frequency (RFID) transmission and utilized the Programmable Integrated Circuit Arduino microcontroller to return the sequence to normal before the emergency mode was activated. Because another vehicle had to follow a particular path to the emergency car, this technique will decrease accidents that occur often at traffic signal crossings. As a consequence, the project successfully studied and implemented wireless communication in the traffic light control system for emergency vehicles, as well as radio frequency (RFID) transmission. When emergency vehicles pass by a junction, the prototype of this project uses the 434 MHz frequency and operates with the sequence mode of a traffic light, shifting the sequence back to the usual sequence before the emergency mode is activated. This prototype system can be enhanced in the future by regulating real-world traffic conditions, effectively upgrading current traffic signal system technology.
