The aim of the project is to develop an automated railway gate at a level crossing, replacing the gates operated by the gatekeeper. This system is capable of detecting train arrival and automatically closes the gate. After the departure of the train, the gate will be automatically opened with a Buzzer indication. This system provides safety to the road users by reducing the accidents. By the presently existing system once the train leaves the station, the station master informs the gatekeeper about the arrival of the train through the telephone. Once the gatekeeper receives the information, he closes the gate depending on the timing at which the train arrives. Hence, if the train is late due to certain reasons, then gate remain closed for a long-time causing traffic near the gates. By employing the automatic railway gate control at the level crossing the arrival of the train is detected by the sensor placed near to the gate. Hence, the time for which it is closed is less compared to the manually operated gates and also reduces the human labor. This type of gates can be employed in an unmanned level crossing where the chances of accidents are higher and reliable operation is required. Since, the operation is automatic; error due to manual operation is prevented. Automatic railway gate control is highly economical microcontroller-based arrangement, designed for use in almost all the unmanned level crossings in the country.

The main objectives of the project are:  

• Automated railway gate control system at level crossings with a buzzer indication.
• Sensor based detection of train arrival and departure.
