Description
Summary:	Crash modification factors (CMFs) and functions are developed from historic crash data and help safety professionals estimate the expected safety impacts of specific roadway treatments. There has been a significant amount of research to develop CMFs for common safety strategies and many are included in the American Association of State and Highway Transportation Officials Highway Safety Manual and Federal Highway Administration CMF Clearinghouse. [This report] presents a guide for using alternative, or surrogate, measures of safety for developing CMFs and other quantifiable measures of safety performance.
