This project focuses on improving road safety by helping prevent chain collisions and reducing the impact of high-beam glare. It uses an IoT-based system that enables real-time communication between vehicles and supports automatic braking when needed.ESP32 microcontrollers coordinate various sensors to detect obstacles, monitor blind spots, and sense accidents. If a collision is detected, Zigbee communication is used to instantly alert nearby vehicles, which can automatically apply brakes to avoid further incidents.To reduce high-beam glare, LDR sensors detect bright headlights from oncoming traffic and automatically switch the vehicle’s lights to low beam. Additionally, a central hub sends accident notifications to emergency contacts via Telegram, ensuring quick assistance in critical situations.
