Purpose and Background

Access Management (AM) is the proactive management of vehicular access points to land parcels adjacent to all manner of roadways. Good access management promotes safe and efficient use of the transportation network. AM encompasses a set of techniques that state and local governments can use to control access to highways, major arterials, and other roadways. This webinar discusses access management techniques that have potential application to highways and streets. The webinar is organized to describe the context in which access management is commonly used; the governments role in managing access, including guidelines and driveway design; other access management techniques; and, land use strategies that local jurisdictions can use as part of an integrated access management program for entire corridors.

Access management applies roadway and land use techniques in order to preserve the safety, function, and capacity of transportation corridors. The objective is to ensure roadway safety and efficient operations while providing reasonable access to the adjacent land uses. Access management can also improve the environment for pedestrians, bicycles, and motor vehicles in all settings and on all roadway types by reducing and consolidating driveway conflict points. In addition to the insight provided by the instructor, the webinar draws on numerous publications including Access Management Manual (TRB), and A Guidebook for Including Access Management in Transportation Planning (NCHRP) to provide valuable information on the development of access management programs. The webinar will also show examples of where access management strategies may sometimes prove to be counterproductive if not implemented according accepted best practices.

Primary Discussion Topics

• Principles and effects of access management
• Proven safety countermeasures through corridor access management
• Access management techniques and their potential advantages AND disadvantages
• The interrelationship with land development and how to address access management in the context of comprehensive planning and land development regulation
• The rationale for spacing standards and how to choose appropriate standards for connections, signals, corner clearance at intersections, and interchange areas
• Challenges of Access Management Codes adopted by State Transportation Departments

Learning Outcomes

• Identifyat least 10 methods for improving access along major travel routes
• Identifyat least 10 mistakes caused by inadequate driveway location and design
• Successfully describe three applications from the case studies on corridor access management upgrades
• Cite at least 15 relevant technical publications for improving access management along important transportation corridors
