Speed-sensitive level crossing barrier control system: an approach to enhance safety and efficiency

OpenAlex · İngilizce

Conventional operator-based level crossing systems often cause long waiting times and unsafe driving behavior due to uniform barrier responses. This study introduces a speed-sensitive control system that adjusts barrier operation according to train velocity. Vibration sensors placed on the tracks detect train speed and classify it as slow, medium, or fast using an Arduino-based unit. The system automatically optimizes barrier closing times to reduce delays while maintaining safety. Tests conducted on a 1/22.5-scale railway model confirmed that the proposed method effectively shortens waiting periods, prevents risky crossings, and improves traffic flow. The prototype demonstrates a practical, low-cost solution that can be integrated into real railway networks to enhance both operational safety and efficiency.
