In road safety analysis, CMF stands for

Explanation:
CMF stands for Crash Modification Factor. It’s the numeric value used to express how a safety countermeasure is expected to change crash frequency compared with the situation without the countermeasure. A CMF less than 1 indicates a reduction in crashes, while a CMF greater than 1 indicates an increase; a CMF of 1 means no change. CMFs are derived from empirical studies and are used to estimate the safety impact by multiplying the baseline crash count by the CMF to forecast post-implementation crashes. The other phrases aren’t standard terms used in road safety analysis.
