Access ManagementAccess management is the systematic control of the location, spacing, design, and operation of driveways, median openings, interchanges, and street connections to a roadway. The purpose of access management is to provide vehicular access to land development in a manner that preserves the safety and efficiency of the transportation system.

By managing access, government agencies can increase public safety, extend the life of major roadways, reduce traffic congestion through improved traffic flow, support alternative transportation modes, and improve the appearance and quality of the built environment. When implemented effectively, access management provides a cost-effective approach to meeting transportation needs. Results of successful implementation of access management techniques include:

  • Allowing motorists to operate vehicles with fewer delays, fewer emissions, and less fuel consumption;
  • Providing reasonable access to properties;
  • Maintaining the functional integrity and efficiency of the roadway;
  • Protecting investments in infrastructure; and,
  • Coordinating transportation and land use decisions.

An Access Management Video From the FHWAInadequate access management can be costly for government agencies, taxpayers, and businesses. As road conditions deteriorate, cities and towns are forced to build new roads or rehabilitate and retrofit existing roadways. Reconstructing major roadways is costly and disruptive to the public, abutting homes, and businesses.

Access management programs slow the deterioration of roadways and protect taxpayer investments in infrastructure. Programs seek to limit and consolidate access along major roadways, while promoting a supporting street system and unified access and circulation systems for development. When implemented effectively, access management provides a cost-effective approach for accomplishing transportation goals, which benefits the general public as well as government agencies and taxpayers.

In 2012, the Federal Highway Administration published guidance on proven safety measures that reduce highway fatalities. These measures included corridor access management, roundabouts, and medians. Each of these techniques are components to the successful implementation of access management.
