Monograph

These 13 papers are concerned with safety data, analysis and evaluation. Specific topics discussed include the following: calibration of the Highway Safety Manual's accident prediction model for a secondary road network; speed and safety; accident modification functions; elementary units of exposure; identifying crash hot spots; safety of lane and shoulder width combinations on rural roads; effects of pavement marking retroreflectivity on traffic crash frequency; road data aggregation and sectioning for crash analysis; safety evaluation of curve delineation improvements; microsimulation to study a traffic signal incident reduction function; comparison of simulated freeway safety performance with observed crashes; traffic operation measures in the safety analysis of signalized intersections; and different parameterizations of the varying dispersion parameter as a function of segment length.
