TDOT - Access Management Report

This report serves as a source of guidelines to assist Tennessee Department of Transportation (TDOT) in its efforts to regulate access management in transportation projects throughout the State of Tennessee. The focus of this document is on recommended practices for access spacing and access design. A comprehensive review of Transportation Research Board (TRB) manuals, National Cooperative Highway Research Program (NCHRP) reports, Federal Highway Administration (FHWA) guidelines and State manuals illustrates current applications of access management regulations to help preserve the functional integrity of the state highway system, promote safe and efficient movement of people and goods and provide reasonable access. Recommendations are provided for access management standards on signalized access spacing, unsignalized access spacing (intersection, driveway and corner clearance), median opening spacing and interchange spacing. Furthermore, best practices are presented on driveway and median geometrics, u-turns and turning lanes design and on retrofitting techniques.
