Abstract	Schultz, Thongs Gordon. Ph.D., Purdue University, August I965. Evaluation of Safety at Railroadhip;hway Grade Crossings . I la jor Professor: Joseph C. Onnenlander. The purpose of this research investigation was to analyze the effects of environment, tonography, geometry, and highway and rail traffic patterns with respect to rail-highway grade crossing accidents in rural areas. The mathematical tools of factor analysis and regression analysis •-ere used to develop models for Dredicting the relative hazard at a railroad grade crossing. These models are based on rail volume, highway volume, and roadside distractions, such as houses, businesses and advertising signs. To evaluate the proposed mathematical relationships, it was necessary to collect sufficient data on many variables deemed to have an influence on safety. Therefore, 56 variables were measured at tho 239 accident locations and 23 variables at the 2U-1 non-accident locations. Previous research efforts were concerned either with long period accident experience or with beforeandafter studies of tho various protection devices. In this research, locations which experienced accidents in a two-year period were compared to non-accident locations. The results of this study can be used to determine the type of protection which a cross-
