What is the primary purpose of a Crash Modification Factor (CMF)?

Explanation:
CMF, or Crash Modification Factor, is a multiplier used to estimate how a safety countermeasure changes crashes. You apply it to the baseline crash count to forecast crashes after the countermeasure is installed: a CMF below 1 indicates fewer crashes, while a CMF above 1 suggests more crashes. This helps planners compare potential safety benefits and cost effectiveness of different countermeasures. It’s not about predicting traffic volumes, measuring speed limits, or directly evaluating road geometry.
