Safety Calculation Model of Grade Crossings with Automatic Barrier System

Abstract

Rail transportation systems are among the types of transportation that are used extensively for reasons such as transportation safety and efficient structure. One of the most important parameters in rail transportation systems is the infrastructure systems used. Infrastructure systems used in areas where rail system lines intersect with highway systems can be listed as underpasses, overpasses, and grade crossings (GC). Although their use is risky, grade crossings continue to be used because underpasses and overpasses cannot be established for all intersections. Among the grade crossings, automatic barrier grade crossings appear as the safest structures. When grade crossings with automatic barriers are examined, it is observed that different parameters affect safety, and it is possible to make predictions for crossing safety. It has been observed that basic grade crossing features, location, physical structure, human and environmental factors, and signboards are effective while performing the safety assessment. In this study, the safety calculation model created for the safety calculation of grade crossings with automatic barriers has been transferred.
