Abstract:

Safety performance functions (SPFs) are integral to the roadway safety management process and Highway Safety Manual (HSM) predictive method. In the roadway safety management process, agencies use SPFs to screen their network for sites with potential for improvement and to account for changes in traffic volume when estimating the safety effects of completed projects. In the predictive method, analysts combine the crash predictions from SPFs with observed crash history to estimate the expected safety performance of design alternatives.
