The document describes an automatic railway gate control system that uses sensors to detect approaching and departing trains. When a train is detected approaching, the system calculates the time needed for the train to reach the road and then closes the gate/barrier accordingly. Another sensor detects when the train departs and then the gate/barrier is restored to its initial open position. This automatic system aims to avoid human errors and improve efficiency compared to manual railway crossing systems.

- 1. AUTOMATIC RAILWAY GATE CONTROL SYSTEM
- 2. Project Synopsis: Railway safety is a crucial aspect of rail operation system worldwide. The purpose of our project is to design an AUTOMATIC RAIL CROSSING SYSTEM. This system is capable of closing the gate/barrier when a train is going to cross the road and the system will be restored to its initial condition after the train leaves. Thus it saves time and man power and reduces the chance of error.
- 3. 1. Previously, no gate or barrier was used at rail crossings. 2. After some period, flagmen were posted to rail crossings to warn the traffic about the incoming train. Generally they used flag or lamp to do their job. 3. Later manually controlled barricades were introduced. The gates were intended to be a complete barrier against intrusion of any road traffic on the railway.
- 4. 1. Manual rail crossings need a lot of man power to do the job of signaling and operating the barrier. 2. So manual rail crossing is not cost efficient. 3. Most of the time this procedure is not time efficient. Often train arrives a long time after the gate has been closed. 4. Manual system is erroneous, and can cause severe damage which may worth a heavy loss of life and capital.
- 5. To avoid human error and to enhance efficiency, railway crossing system can be controlled in an automated manner. In an automatic rail crossing system a train which approaches the gate is detected by a sensor, and also the speed of the train is noted. Then the time taken by the train to reach the road is calculated and the gate/barrier is closed down accordingly. Also the departure of the train is detected by another sensor and the gate/barrier is restored to its initial position.
