The Crash Modification Factors (CMF) Clearinghouse provides transportation professionals:
The CMF Clearinghouse brochure provides general information related to the Clearinghouse, and can be used to promote this valuable resource to state and local transportation professionals. CMF Clearinghouse Brochure [HTML, PDF 2.27 MB] PublicationsCMFs in Practice NEW! A Guide to Developing Crash Modification Factors Desktop Reference for Crash Reduction Factors FHWA has developed a set of resources to assist practitioners in their decision-making process. These resources are developed around FHWA’s Office of Safety focus areas of intersection safety, pedestrian safety and roadway departure safety.
The CRFs presented in the Desktop Reference are a compilation of all the CRF information available to date; whereas, the CRF’s contained in the “Toolbox of Countermeasures” for intersection, pedestrian and roadway departure crashes contain the “best” available information on countermeasure effectiveness in terms of CRF’s. The Desktop Reference for Crash Reduction Factors will NOT be updated in the future to reflect new CRFs. All CRFs in the Desktop Reference are reflected in the CMF Clearinghouse at http://www.CMFclearinghouse.org. All newly developed CMFs/CRFs will be added to the CMF Clearinghouse on a regular basis (at least quarterly). |
