Abstract: The purpose of the study was to examine currently used measures of exposure to risk and to develop new methods for defining these exposure counts. The research was conducted to provide the basis for developing more accurate accident rates in order to produce more sensitivity in countermeasure evaluation and problem identification studies. The method used in developing the exposure measures involved defining the relevant accident types for a given highway situation based upon the possible interactions between pairs of vehicles or a vehicle and roadside objects. Resultant exposure measures are provided for analysis of intersections, interchanges, roadway segments, fixed object collisions, and research relating to accidents by vehicle class. The report is the second in a series.
