What is the primary use of CMFs in safety analysis?

Explanation:
CMFs quantify how a safety treatment or road feature will change crash frequency. By applying a CMF to the current or expected baseline crashes, you estimate how many crashes would occur after implementing the change. This allows you to compare different safety options and forecast the safety impact as part of the analysis. CMFs come from studies and crash data and indicate reductions (CMF less than 1) or increases (CMF greater than 1) in crashes due to the feature. They’re not used to measure weather patterns, assess vehicle maintenance, or set speed limits.
