Local Agency Access Management

Local agencies in Washington State constantly weigh the competing needs of access to property, mobility of travel, and safety along highways, roads, and streets.

According to the Transportation Research Board's 2014 Access Management Manual, "Access management is the coordinated planning, regulation, and design of access between roadways and land development. It involves the systematic control of the location, spacing, design, and operation of driveways, median openings, interchanges, and street connections to a roadway, as well as roadway design applications that affect access. (These include such things) as median treatments and auxiliary lanes, and the appropriate separation of traffic signals."

The following are resources for local agencies on access management.
