This paper presents a real-time traffic management system designed to prioritize emergency vehicles such as ambulances through interrupt-driven traffic light control integrated with the Blynk mobile application platform. Emergency response vehicles encounter challenges navigating through traffic efficiently, often resulting in delays that could impact critical medical situations. Traditional traffic light systems lack the agility to accommodate emergency vehicles promptly. “Perform Real Time Interrupt on Traffic Light” requires an ESP 32 to activate the whole system to the traffic lights. This project approach is to make sure ambulances has the privilege to operate the traffic lights system using the Blynk mobile application. When the system starts running, the app will have the option to select a junction following the junction they currently at and the traffic light will automatically switch to green lights.
