Development of Crash Modification Factors (DCMF) Publications
The DCMF Program Studies
A goal of the DCMF program is to advance highway safety and related research by establishing a sound foundation for the development of statistical methodologies that need to be specifically developed for highway transportation applications in cooperation with the American Statistical Association (ASA) and other statistician communities. In pursuit of that goal, a 2-day Technical Experts meeting brought together researchers from the road safety and statistics fields and other fields related to statistics—such as epidemiology, biostatistics, and agent-based modeling—that have methodologies relevant to highway safety research applications. The meeting resulted in guidance and materials that supported the development of the publication, which identifies and discusses opportunities for advancing methodologies to estimate crash modification factors and safety performance functions. The publication outlines considerations and future steps to encourage researchers to explore these techniques in their research.
CMF Needs Assessment and Stakeholders Meeting
On May 28, 2014, FHWA hosted a Crash Modification Factor (CMF) Stakeholder Meeting to provide a forum for CMF stakeholders to communicate ongoing efforts and identify opportunities for future collaboration. CMF stakeholders represent two primary groups: the CMF user community (transportation agencies and practitioners) and the CMF research and development community (individuals and agencies who plan, fund, direct, and carry out CMF research). Bringing these stakeholders together provided an opportunity to share insights and resources to further advance the research and development of CMFs and related activities.
The CMF Needs Assessment study was completed in June 2014, and its products below were used to enhance FHWA, CMF Clearinghouse, and related CMF studies.
