Iot Enabled Smart Traffic System For Emergency Vehicles

Abstract

Road Accidents Often Result In Severe Consequences Due To Delays In Emergency Detection And Response. Conventional Systems Rely On Manual Reporting Or Single-sensor Mechanisms, Which May Lead To False Alerts And Slow Assistance. This Paper Proposes A Smart Accident Detection And Emergency Response System That Integrates Multi-sensor Monitoring With Real-time Communication And Intelligent Traffic Signal Control. The Vehicle-mounted Unit Utilizes A Vibration Sensor, Accelerometer, Gas Sensor, SpO₂ Sensor, And GPS Module To Detect Abnormal Conditions. A Timer-based User Confirmation Mechanism Is Incorporated To Minimize False Emergency Notifications. Upon Confirmation, Accident Data Along With Location Coordinates Are Transmitted Via Wi-Fi To A Mobile Application For Ambulance Coordination And Navigation. To Reduce Response Time Further, A Traffic Signal Preemption Mechanism Dynamically Assigns Green Signal Priority To The Ambulance Approach Lane, Overriding Normal Signal Cycles. The System Is Implemented Using An ESP8266- Based Architecture, Providing A Reliable And Cost-effective Solution For Real-time Accident Management And Smart Traffic Control.
