U-Bend Accident Prevention Through Lora Communication

With the rapid development of wireless communication technologies, communication among the vehicles has become a crucial component in modern intelligent transportation systems.This paper presents a long-range, low-power communication system using LoRa (Long Range) technology to enhance road safety and vehicle coordination.The system utilizes Arduino-based controllers equipped with LoRa modules, ultrasonic sensors for obstacle detection, and emergency alert mechanisms.The objective is to provide real-time data exchange between vehicles, allowing them to react proactively to potential hazards.Ultrasonic sensors are employed on each vehicle to detect obstacles in the surroundings, while push button switches are provided for emergency situations, triggering alerts.In case of an emergency, a buzzer is activated, providing an audible warning.The data is communicated between the vehicles using the LoRa modules, allowing for real-time alerts and status updates on each vehicle's condition.The system is powered by 12V adapters and features LCD displays to show the status of each vehicle's sensors.This approach aims to improve road safety by enabling vehicles to communicate and respond proactively to obstacles and emergencies.The proposed solution addresses the limitations of conventional short-range communication technologies like Wi-Fi and Bluetooth by offering an extended transmission range with minimal power consumption.This study explores the feasibility, design, and implementation of the system, highlighting its benefits in improving vehicular safety and reducing accident risks.
