How to Measure and Communicate the Value of Access Management

NCHRP Research Report 1032 presents a state-of-the-art guide on measuring and communicating the value of access management. The guide is accompanied by a complementary toolkit (the Access Management Communication Toolkit) with messaging strategies, spreadsheet tools, fact sheets, as well as a series of case studies and videos illustrating the toolkit application. The guide and associated tools and methods were developed based on an extensive literature review, survey, research, and interviews with state transportation agencies. These project deliverables are designed for immediate use by new and experienced practitioners in their efforts to implement access management plans, programs, or projects. Effective ingress and egress management along highways and major arterial roads are essential for minimizing road-user conflicts. Closely spaced driveways, median openings across turn lanes, and driveways near major intersections are examples of poorly designed access features that contribute to unsafe, unsightly, and congested roadways. Access management techniques—used to minimize potential conflict points—help reduce crashes, preserve roadway capacity, improve corridor aesthetics, and reduce congestion. Well-managed transportation corridors also benefit from more stable property values, less delay to freight movers and the commuting public, and better market reach for retail businesses. Research on the benefits of access management has focused mainly on operational and safety effects and the economic impact of access changes on businesses. Little focus has been placed on the economic impacts to transportation agencies that may result from poor access management decisions or the lack of access management planning. Transportation agencies that do not successfully implement access management often incur additional costs as roadways and interchanges are reconstructed or replaced. Research was needed to help these agencies—charged with making prudent access management decisions—demonstrate and articulate the benefits of access management at the program, corridor, and project levels. Under NCHRP Project 25-47, the University of South Florida was asked to develop a guide for transportation agencies on measuring and communicating the value of access management at all levels. The guide involves research-based techniques to identify, measure, and assess the benefits and costs of access management using both quantitative and qualitative metrics.
