Design and Development of Automatic Railway level crossing system.

Abstract

This paper proposes an affordable, Arduino-based automated level crossing system to enhance safety at train crossings in Bangladesh. Ultrasonic sensors accurately detect approaching trains up to 4m and trigger sequential road gates closure via microcontroller-controlled actuators. Warning lights are activated prior to gate closure to alert vehicles. The system timing is designed for 60km/h train speeds using entry and exit sensors to track the full-length train through the crossing. The microcontroller code filters sensor data to avoid false triggers. Solar power and load sensors are suggested to refine the system. With strategic sensor placement and precise timing, this automated system can operate crossing gates without human intervention. The estimated 2950 Taka cost makes it viable for high-risk intersections in Bangladesh. Further testing and calibration are recommended before full-scale deployment for significant public safety benefits. This low-cost automated solution has the potential to reduce accidents at level crossings
