Synthesis of Information Related to Highway Practices. Topic 52-08. Practices for Balancing Safety Investments in a Comprehensive Safety Program

Most state departments of transportation (DOTs) use at least a portion of their Highway Safety Improvement Program (HSIP) funds on systemic safety improvement projects. However, DOTs continue to be challenged in determining how to prioritize projects and allocate funding across the various improvement types (i.e., spot, systemic, and systematic) to maximize safety benefits within their limited safety budgets. The Federal Highway Administration (FHWA) provides guidance to help DOTs determine the appropriate balance of investments between the different project types. Some DOTs choose investments based on a benefit-cost ratio, while others have challenges applying benefit-cost analysis procedures for systemic safety improvement projects. In these cases, DOTs may set aside a portion of their safety funds for systemic or systematic projects. The objective of this synthesis is to document current DOT practices of identifying and prioritizing highway safety projects. Information gathered includes (but is not limited to): Current state of the practice of prioritizing projects; Use of separate budgets set aside for safety investments; Funding allocations across the various improvement types; and Use of benefit-cost analysis for systemic projects, including identifying risk factors, project selection/prioritization, and evaluation of the effectiveness of systemic improvements. Information will be collected through literature review, a survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
