EXPOSURE MEASURES FOR EVALUATING HIGHWAY SAFETY ISSUES: VOLUME 1--FINAL REPORT

This research covers five main areas for which appropriate exposure measures have been developed, and the following chapters deal with each of these in turn. Chapter 2 covers intersections and includes discussion of the associated concerns of free flow, stop sign, or signal controlled intersections as well as single lane versus multi-lane configurations. Chapter 3 deals with interchanges and the exposure measures related to the various interchange segments (e.g., through lanes, on-ramp merge, off-ramp diverge, weaving areas, etc.). Chapter 4 concerns homogeneous roadway sections--both single and multi-lane--that often are examined for problem identification purposes (i.e., questions about which sections of roadway should be improved). Fixed objects are covered in Chapter 5 from two points of view: (1) exposure measures for determining a fixed object accident rate, and (2) exposure measures which enable one to compare the degree of hazard for various types of fixed objects. Finally, Chapter 6 presents exposure measures necessary for use in accident research questions involving specific types of vehicles such as heavy trucks, small cars, motorcycles, etc.
