A crash modification factor (CMF) is a measure of the safety effectiveness of a particular treatment or design element. CMFs are applied to the estimated crashes without treatment to compute the estimated crashes with treatment. (Crash modification factors (CMFs) support a number of safety-related activities in the project development process. The CMFs in Practice series includes five separate guides that identify opportunities to consider and quantify safety in specific activities, including roadway safety management processes, road safety audits, design decisions and exceptions, development and analysis of alternatives, and value engineering. The purpose of the CMFs in Practice series is to illustrate the value of CMFs in these five activities and demonstrate practical application of CMFs.) (Author/publisher)
