Careful management of access points along crossroads in the vicinity of interchanges can help enhance operational and safety performance at these complex, transportation facilities.

The TRB National Cooperative Highway Research Program's NCHRP Research Report 977: Access Management in the Vicinity of Interchanges, Volume 1: Practitioner’s Guide provides an overview of common interchange configurations and the known impacts of access management on crossroads at these locations.

Supplemental to the report is NCHRP Research Report 977: Access Management in the Vicinity of Interchanges, Volume 2: Research Overview; a suite of PowerPoint slides on the Importance of Access Management, Influential Factors, Assessment Methods, a Case Study Example, and Management Methods; and the Access Management Interchange Decision Tool, which is a spreadsheet for estimating expected corridor speeds as they relate to driveway spacing guidelines.
