Synthesis of Information Related to Highway Problems. Topic 40-11. The State of Practice in Highway Access Management

Access management is a practice of improving the design and placement of driveways and medians, with the goal of limiting traffic conflicts. Access management can achieve significant improvements in both highway operations and capacity. It can achieve reductions in crash rates of as much as 50 to 60 percent. The most recent Texas Transportation Institute (TTI) Urban Mobility Study also indicates that improved access management could make a significant contribution to congestion reduction on a nationwide basis. Several NCHRP research studies, work by the Transportation Research Board (TRB) Access Management Committee and publications by TRB and the Federal Highway Administration (FHWA) have all helped provide information and materials to state agencies to adopt and modernize their access management and access control programs. This synthesis will study how states have acted on these national efforts, what have been the barriers to action, and how new national efforts might be focused to improve the implementation of access management strategies and treatments nationwide.
