Introduction

I. INTRODUCTION

In emergency situations, time is of the essence, and the efficiency of emergency services can be a crucial factor in determining outcomes. Emergency responders often encounter challenges in swiftly navigating through traffic to reach their destinations. Traffic congestion and signal delays can significantly impede response times, potentially affecting the outcome of critical situations. To address this issue, Traffic Light Priority for Emergency Vehicles has been conceptualized as a solution. This system is designed to grant priority to emergency vehicles at traffic signals, allowing them to override the standard traffic light sequence. When activated, the system facilitates the safe and expedited passage of emergency vehicles through intersections. This paper delves into the implementation of Traffic Light Priority for Emergency Vehicles, exploring its benefits, challenges, and potential solutions. The impact of this technology on traffic flow and the overall efficiency of emergency response systems is examined. Additionally, the discussion extends to the potential future developments of this technology and its capacity to enhance emergency services on a global scale.In urban environments, emergency vehicles such as ambulances, fire trucks, and police cars often encounter delays due to traffic congestion, posing life-threatening risks in critical scenarios. The objective of this project is to develop an intelligent traffic light system that facilitates the swift and secure movement of emergency vehicles through traffic.
