Project title: Enhancing Railway Safety with An Automated Level Crossing Control System Utilizing Ultrasonic Sensor, LoRa, and GSM Module

Abstract—Railway safety remains a critical concern worldwide, with level crossings being particularly vulnerable points prone to accidents. The existence of enormous unauthorized level crossings, lack of proper management from authorities, absence of protective measures in the crossings, and ignorance of the pedestrians and vehicle drivers are a few of the major reasons for such horrifying accidents. This project presents an innovative approach to enhance railway safety through the implementation of an automated level crossing control system. The system integrates advanced technologies, including ultrasonic sensors, pressure sensors, Long Range (LoRa) communication, and Global System for Mobile Communications (GSM) modules.

The core of the system revolves around ultrasonic sensors deployed to detect the presence of approaching trains. The utilization of LoRa technology facilitates seamless communication between the level crossing control system and the railway infrastructure. LoRa's long-range capabilities ensure reliable data transmission over extended distances. This enables real-time monitoring and management of the entire railway network, enhancing overall safety and efficiency. Pressure sensors are employed to detect vehicles stuck over the railway track. Protection barriers are controlled by servo motors to guide the incoming vehicles and pedestrians across the crossings. An alarm system containing signal lights and buzzers is incorporated in the system to make the pedestrians and vehicle drivers aware of the urgency of moving away from the crossing points while a train is approaching. Furthermore, the integration of GSM modules allows railway drivers to receive instant alerts regarding system malfunctions or potential safety hazards, facilitating prompt response.

Overall, the proposed automated level crossing control system offers a comprehensive solution to enhance railway safety. By leveraging ultrasonic sensors, LoRa communication, and GSM modules, the system ensures timely detection of approaching trains and effective deployment of safety measures, thereby mitigating the risk of accidents at level crossings and contributing to a safer railway environment.
