Abstract:The Nevada Department of Transportation (NDOT) plays a key role in addressing highway-rail grade crossing safety issues by allocating federal funding through the Railway-Highway Crossing (Section 1030) Program. This Program requires each state to select eligible projects through a data-driven project selection and prioritization process. NDOT currently relies on the use of a modified version of the New Hampshire Hazard Index formula for this project prioritization. However, NDOT feels that the results of this formula have not accurately reflected actual safety needs of many crossings throughout the state. This report summarizes current grade crossing safety trends in Nevada and at the national level, reviews the strengths and weaknesses of NDOT’s current grade crossing safety prioritization procedures, and evaluates potential alternative hazard index models used by other agencies. This report also includes summaries of peer interviews with the Arizona, Oregon, and Utah Departments of Transportation and also includes a summary of feedback received from an Expert Panel consisting of representatives from NDOT, the Federal Railroad Administration, Federal Highway Administration, Union Pacific Railroad, and others. Finally, the report proposes a revised Hazard Index Model for consideration as a replacement for NDOT’s current model.
