Guide for Quantitative Approaches to Systemic Safety Analysis

The objectives of this research are to develop a guide and training materials to assist state departments of transportation (DOTs), metropolitan planning organizations (MPOs), local agencies, and other safety practitioners to better understand, use, and implement quantitative approaches to systemic safety analysis. The research results may be incorporated in a future edition of the AASHTO Highway Safety Manual. The final deliverable(s) for this research should: Clearly define quantitative approaches to systemic safety analysis and distinguish them from other approaches for identifying safety improvements such as traditional (e.g., “hot spot”) and systematic (i.e., implemented system wide) approaches; Communicate the benefits of quantitative approaches to systemic safety analysis for identifying safety improvements; Provide a review of existing methods and tools to conduct quantitative approaches to systemic safety analysis, including but not limited to, the FHWA Systemic Safety Project Selection Tool, usRAP Tools, and AASHTOWare Safety Analyst; Provide a review of how other guidebooks, tools, software, resources, and ongoing research may be applicable to quantitative approaches to systemic safety analysis; Present the data needs for the various methods and tools to successfully implement quantitative approaches to systemic safety analysis; Specify and define appropriate applications (e.g., roadway functional classification, crash type, segments vs. intersections) for the various methods and tools for quantitative approaches to systemic safety analysis; Provide a critique and capabilities assessment of each method and tool that agencies could use for quantitative approaches to systemic safety analysis; Recommend current best practices and potential revisions that would increase the effectiveness or improve the ease of implementation of the methods and tools for quantitative approaches to systemic safety analysis; and Recommend or develop methods that agencies may use to evaluate the results (i.e., safety impacts) of improvements that were implemented using quantitative approaches to systemic safety analysis.
