- Railway level crossings are critical points where road traffic intersects with railway tracks, often leading to accidents due to human error or malfunctioning systems. This review paper explores existing technologies and approaches for enhancing safety at these crossings, focusing on automated systems for real-time obstacle detection and gate management. Various sensor-based solutions, including infrared, ultrasonic, and image processing techniques, are examined for their effectiveness in detecting obstacles such as vehicles, pedestrians, or debris. These systems aim to alert both road users and trains through alarms, flashing lights, and barrier controls to prevent collisions. Additionally, the review discusses automation of level crossing gates using GPS or track-based sensors to open and close gates without human intervention. Such automation reduces reliance on manual operations and minimizes the risk of errors, improving overall safety. The paper highlights the potential for integrating these systems into existing infrastructure, offering a cost-effective approach to modernizing railway crossings. Through the review of current technologies and studies, this paper aims to provide insights into the future development of automated, real-time safety systems at railway intersections.
