Crash Modification Factor (CMF) Tool Update

Crash Modification Factors (CMFs) are used to estimate how many crashes will occur if a countermeasure were implemented. A primary source of CMFs is the CMF Clearinghouse. Because the quality of CMFs varies, determining which to use demands significant time and expertise. Kentucky Transportation Center (KTC) researchers have developed a web-based tool that Kentucky Transportation Cabinet (KYTC) staff, consultants, and other highway safety partners can use to search for and identify CMFs most appropriate for the project at hand. Since work on this tool was completed, the CMF Clearinghouse has been updated with 6,000 new CMFs and new methods for assigning star quality ratings. As such, the web-based search tool needs to be updated to include all CMFs that are now in the CMF Clearinghouse.
