Synthesis of Information Related to Highway Practices. Topic 50-05. Incorporating Roadway Access Management into Local Ordinances

Managing access connections to roadways is vital to safety and operational performance of roadways for all users. Given the separation of authority between state and local governments over land development and access, intergovernmental coordination is integral to effective access management. The TRB National Cooperative Highway Research Program's NCHRP Synthesis 549: Incorporating Roadway Access Management into Local Ordinances documents regulatory tools and practices used by local governments to implement access management, as well as provides examples of how state transportation agencies are coordinating with local governments to advance access management objectives. The review of local ordinances and state and local government coordination practices indicates that access management is being actively implemented throughout the United States. Typical features of local ordinances reviewed included access classification schemes and corresponding spacing standards, interparcel cross access requirements, intersection functional area or corner clearance standards, limits on driveways per site, unified access and circulation requirements for outparcels, allowances for deviations from standards, and access permitting and development (site plan) review procedures and criteria.
