Smart Accident Prevention Mesh Network using Zigbee Communications

Abstract

A Zigbee-enabled smart zone system is introduced to enhance road safety through Vehicle-to-Vehicle (V2V) communication using ESP32 microcontrollers. The approach utilizes Zigbee transceivers to facilitate real-time wireless data exchange between nearby vehicles, enabling early detection of potential collision scenarios within predefined smart zones. On the receiver side, an ultrasonic sensor continuously measures the distance between vehicles, and when this distance drops below a safe threshold, a buzzer alert is generated along with the activation of a DC motor-driven braking mechanism. The transmitter unit, supported by a regulated power supply, sends vehicle-related data via Zigbee to the ESP32, which processes the information and displays system status on an LCD module. Experimental evaluation indicates that the system effectively minimizes the likelihood of accidents in critical areas such as school zones, intersections, and highway merging points by delivering timely warnings and automated safety responses.
