Abstract: This project presents a Zigbee-based Nearby Vehicle Accident Alert System designed to enhance road safety by providing real-time accident notifications to nearby vehicles and emergency services. The system employs Zigbee technology, a low-power, cost-effective wireless communication protocol, to establish a network between vehicles and roadside units.

When an accident is detected using onboard sensors like tilt sensor, the system triggers an automatic alert, transmitting critical information such as the location, time, and severity of the incident to nearby vehicles and emergency responds within the Zigbee network range. This immediate communication helps quicker emergency response, and improves the overall efficiency of post-accident management. The system's low power consumption and reliable communication capabilities make safer road environments.
