The Grade Crossing Accident Prediction System (GXAPS) is an analytical computer model that provides information to  assist governmental agencies and railroads in determining where highway-rail grade crossing resources can best be directed.

GXAPS generates reports listing public highway-rail intersections for a state, county, city or railroad ranked by predicted collisions per year. These reports include brief lists of the current inventory record and the collisions over the past 10 years, along with a list of contacts for further information.
