Automatic Barricade System in Railways

The increasing number of accidents at unmanned railway crossings presents a critical challenge to public safety. This project proposes an Automatic Barricade System in Railways using an Arduino Uno microcontroller, designed to minimize human intervention and ensure timely gate operations. The system utilizes two Infrared (IR) sensors placed at a calculated distance before and after the railway track to detect the presence and movement of a train. Upon detecting an approaching train through the first IR sensor, the Arduino activates a DC motor to automatically lower the barricades on both sides of the track. Simultaneously, a red warning light and a buzzer are triggered to alert nearby vehicles and pedestrians. Once the train passes the second IR sensor, indicating it has cleared the crossing, the system deactivates the warning signals, and the motor raises the barricades, with the green light turning on to signal safe passage. This system enhances safety at railway crossings, especially in rural or unmanned locations, offering a cost-effective and reliable automation solution.
