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.
