Railway level crossing warning design in rural area using ultrasonic sensor and wireless communication

Abstract

Collisions between train and roadway user in a level crossing in a rural area are the most railway accidents. A warning device for the level crossing is required to avoid the accident between roadway users and the train in the level crossing. The system shall independent from the existing railway system so that no disruption on the traffic of the train. This paper present a level crossing devices system based on ultrasonic sensors and wireless communication. Master control will display the result of detection using buzzer alarm, warning lamp, and train passage direction. Train passage warning with direction helps the roadway user to get a better awareness of incoming train and eliminate assumption of train passage direction. Especially in double track railway in a rural area, in case dual train enter the level crossing from left and right direction, the roadway users sometimes only aware on the first train passage and ignoring the second train and lead to the accident.
