Work has been completed which examined currently used measures of exposure to risk and developed new methods for defining these measures. Exposure was viewed as a measure of the "opportunity to crash" or "opportunity to sustain injury" and it is expected that the exposure measures may change from study to study. Exposure measures were developed for five basic accident research areas: intersection accidents, interchange accidents, accidents at non-intersection roadway segments, fixed object collisions, and accidents involving specific vehicle types. The method used in developing the appropriate expsoure measures involved first defining the basic accident types for a given research question or location and then developing formulas for exposure to crashes for each of these types of accidents. The results of this work are reported in two technical reports and a computerized package suitable for use on a minicomputer. The final technical report describes the development of each of the exposure measures. A user manual was also developed.
