As highway safety has evolved, a number of different methods have been applied to estimate the safety performance of roadway segments. This research summarizes current methods in highway safety analysis and evaluates two alternative methods for estimating the safety implications of roadway features. Methods derived from epidemiological studies are proposed. Epidemiology often seeks to relate risk factors within a population to a particular outcome or disease. In the highway safety context, the qoutcomeq is a crash and the qrisk factorq is a particular geometric feature or countermeasure within a specific population of roadway segments.126.96.36.199 Enhanced Model B: Match on ADT and Speed with Segment Length as a Covariate Estimated CMFs and ... Coefficients are estimated and presented for the effects of segment length on crash risk; however, the objective of this research is focused on the effects of shoulder ... appear to improve after adjusting for segment length and are compared to the CMF presented in the Highway Safety Manualanbsp;...
