• Abstract:
  This manual, which provides measures of exposure for the many different research problems faced by the researcher, focuses on the following areas of exposure measures: intersection accidents; interchange accidents; accidents on non-intersection roadway segments; fixed object collisions; and accidents involving specific vehicle types. Primary emphasis is placed on the first three "location-oriented" areas. Exposure related to basic types of research are considered: basic research and evaluation involving a relatively small number of locations; and problem identification (ranking) or vehicle-oriented studies involving many locations or a statewide jurisdiction. The manual briefly explains the basic measures and the way they were developed as well as the assumptions necessary for their development. Sketches of the components of the location being analyzed and the definitions used in the formulas are presented as well as approximate formulas for each type of relevant exposure. Where possible simplifications are developed and presented.
