The Railway Track Pedestrian Crossing Between Platforms Using a Movable and Flexible Railway Platform is an embedded-system-based safety project designed to prevent accidents caused by passengers crossing railway tracks between platforms. In many railway stations, passengers often take unsafe shortcuts across the tracks instead of using foot overbridges or subways, leading to serious accidents. This project provides an automated movable platform and barrier control system that allows safe pedestrian crossing only when no train is present. The system is controlled by a PIC microcontroller, which receives signals from IR sensors placed at the train entrance and train exit points. When a train approaches, the entrance sensor detects it and the microcontroller activates servo motors to close the pedestrian barriers, preventing passengers from entering the crossing area. At the same time, DC motors are used to retract or move the flexible platform away from the railway track. A buzzer and LED indicators provide audible and visual warnings during train movement. After the train passes the exit sensor, the controller opens the barriers using the servo motors and drives the DC motors to extend the movable platform across the track, creating a safe walkway for passengers to cross between platforms. The proposed system is low-cost, automatic, and suitable for railway stations with heavy pedestrian traffic. It minimizes human intervention, improves passenger safety, and ensures reliable operation through real-time train detection and controlled movement of the barriers and platform. This project demonstrates an effective solution for safe pedestrian crossing between railway platforms using servo-operated barriers and a DC-motor-driven movable flexible platform.

1. Train arrival and departure detection.
