Integrated V2V Communication System

Road accidents continue to rise due to delayed driver response, limited visibility, and lack of coordination between vehicles. Vehicle-to-Vehicle (V2V) communication enhances road safety by enabling cooperative awareness through real-time data exchange. This paper presents a low-cost Integrated V2V Communication System using ESP32 microcontrollers and the ESP-NOW protocol for collision avoidance and driver assistance. The system integrates ultrasonic and IR sensors for obstacle detection, GPS for vehicle localization, and multi-modal alert mechanisms including voice alerts, buzzer, LED indicators, and display modules. Vehicles directly broadcast safety-critical information to nearby vehicles without relying on external infrastructure or cloud connectivity. Experimental results show low communication latency, timely alert generation, and improved driver response, demonstrating the effectiveness of the proposed approach for intelligent transportation systems.
