Imagine a multilane urban/suburban roadway where traffic is heavy, yet moves well; accommodates drivers, pedestrians, and bicyclists; allows easy entry to and exit from businesses and other destinations; and has fewer crashes and other conflicts. Chances are this road is benefitting from corridor access management, a strategy that seeks an appropriate balance between the safety and mobility of a roadway facility with the access needs of adjacent land uses.

While managing access at a single location may help improve safety and operations within an immediate vicinity, application of access management along an extended corridor has been shown to improve safety, mobility, accessibility, and even business along an entire stretch of roadway because it favorably impacts ALL properties along that corridor.

Corridor access management preserves the flow of people and freight, and enables safe access to businesses and neighborhoods using a combination of policies and strategies, such as closing, consolidating, or improving driveways, median openings, and intersections; adding or redesigning medians; and planned spacing of intersections, median openings, and driveways.

Studies conducted by State and local agencies, national organizations, and transportation trade associations consistently show that access management notably improves traffic flow and safety for travelers. In addition, strong evidence shows that it can ultimately improve business in many cases by making it easier to get to and from destinations. The FHWA Office of Safety identified corridor access management as a Proven Safety Countermeasure because of the ability of this strategy to reduce crashes
