Abstract

The high incidence of accidents at railway level crossings due to human errors and lack of proactive track monitoring is a challenge for rail safety in high-density networks. This paper proposes the development and validation of an intelligent automated railway crossing system- IARCS that leverages sensor fusion and IoT communication to eliminate human dependency and mitigate intrusion risks. The core system deploys an Arduino Uno for the purpose of primary gate control, incorporating Ultrasonic Sensors HC-SR04 for precise train approach and departure detection, and a dedicated Passive Infrared PIR Sensor for robust, real-time intrusion monitoring within the crossing zone after the gates are closed. Upon the detection of any trapped obstacle (human or vehicle), a secondary ESP32 microcontroller is activated. The major contribution of this system is its double-layered warning mechanism. Locally, it initiates visual LED and audible Buzzer warnings. Most importantly, it utilizes the ESP32 to establish a low-latency alert path (via LoRa/Wi-Fi and a WhatsApp/Telegram Bot Service) for sending an immediate hazard notification directly to the Locomotive Pilot’s smartphone. The implementation plan, based on a Finite State Machine (FSM) control logic, ensures failsafe and predictable gate operation via a Servo Motor. Performance validation focuses on maximizing detection accuracy and minimizing alert latency, demonstrating that the IARCS offers a reliable, cost-effective, and proactive solution to significantly enhance operational safety and prevent collisions at level crossings.
