Statistical data show that losses caused by railway transportation system accidents are far more severe than those incurred by highway accidents, and most of the railway accidents occur at level crossings. It is necessary and urgent to design a reliable railway crossing security system to effectively reduce the number of accidents. Through the deployment of sensors, this paper discusses how to construct an intelligent level crossing control system to reduce the loss of life and property caused by such accidents. Remote monitoring with single-chip safety control system gives real-time alarm of people or vehicles trapped at the railroad crossing. Furthermore, immediate notifications can be given to train drivers so that necessary measures can be taken in advance. With the assistance of security personnel stationed at level crossings, this intelligent level crossing safety system is expected to significantly reduce accidents.
