The Federal Highway Administration Development of Crash Modification Factors (DCMF) Program was established in 2012 to address highway safety research needs for evaluating new and innovative safety strategies (improvements) by developing reliable quantitative estimates of their effectiveness in reducing crashes. A goal of the DCMF is to advance highway safety and related research by establishing a sound foundation for the development of highway transportation specific statistical methodologies in cooperation with the American Statistical Association and other statistician communities. In pursuit of that goal, a two-day Technical Experts meeting brought together researchers from the road safety, statistics, and other statistics-related fields 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 this white paper, which identifies and discusses opportunities for advancing methodologies to estimate crash modification factors and safety performance functions. The paper outlines considerations and future steps to encourage researchers to explore these techniques in their research. (Author/publisher)
