This report defines the problem of crossing path crashes in the United States. This crash type involves one moving vehicle that cuts across the path of another when their initial approach comes from either lateral or opposite directions and they typically collide at, or near junctions. The frequency, manner of collision, and location of these crashes are described using the 1998 National Automotive Sampling System/General Estimates System (GES) crash database. This report separates crossing path crashes into five common scenarios that represent vehicle movements immediately prior to the crash. The frequency and fatality rate of these crash scenarios are delineated in relation to their occurrence at intersections and at driveways under distinct traffic controls using data from the GES and the Fatality Analysis Reporting System. This report also identifies contributing factors of the major crossing path crash scenarios based on 1998 GES data. In addition to vehicle-vehicle crossing path crashes, this report addresses the problem of vehicle-pedestrian and vehicle-pedalcyclist collisions at intersections and elsewhere. The results of this analysis are intended to support the development of effective countermeasure concepts and provide data for design effectiveness assessments.
