摘要：	Accident modification factors (AMFs), also known as crash reduction factors, provide a computationally simple and quick way of estimating crash reductions. Many states and local agencies have a set of crash reduction factors that are used for estimating the safety impacts of various types of engineering improvements, encompassing the areas of signing, alignment, channelization, and other traffic engineering solutions. Typically, these factors are computed using before-and-after comparisons, although recent research also has suggested the use of cross-sectional comparisons. This report presents the findings of a research project to develop accident modification factors (AMFs) for traffic engineering and ITS improvements. AMFs are a tool for quickly estimating the impact of safety improvements. The report will be of particular interest to safety practitioners responsible for programming and implementing highway safety improvements. / Supplementary Notes: See also PB2005-109960 and PB2007-106636.
