Demosthenes, P. “Practices in Access Management,” ITE Journal, Institute of Transportation Engineers, Washington, D.C., vol 80, issue 1, (January 2010, pp. 46 – 51)

This article provides practical guidance on developing and implementing an access management program. It includes guidance relative to access classification systems, access design practices, variances and corridor access management plans. It will be especially useful in the chapters on access classification systems and state program development.

Design/Development Principles for Livable Suburban Roadways

This research investigates the interaction between road section design and adjacent site design with the goal of pairing roadway design criteria (in terms of the maximum number of lanes and design speed) with urban design criteria (in terms of levels of activity, location of access, and relation to street). The research hypothesizes that a minimum of three arterial roadway prototypes is needed to serve travel demands and that there are three types of activity levels in suburban communities.

Applying Access Management Across the Transect

Presentation Strader, Brad. “Applying Access Management Across the Transect: Complete Streets,” Proceedings of the 90th Annual Meeting of the Transportation Research Board (presentation only), (January 2011) This presentation suggests a simpler adaptation of the CSS transect framework in ITE’s Designing Walkable Thoroughfares (2010) as a means of organizing access management strategies according to context. It also offers several case examples of these applications in typical rural, suburban and urban contexts. Figure 2 illustrates the overall concept.

Designing Walkable Urban Thoroughfares

The context sensitive solutions (CSS) approach keys thoroughfare types with place types that reference aspects of the roadside context. An implicit goal of CSS is to reduce the dominance of roadway capacity in roadway design decisions by more directly integrating other modal and community design considerations – particularly those design details critical to supporting non-auto modes in the urban context. The approach also strives to maintain an optimal balance between desired roadway operations and the roadside context.

Basic elements of the approach are as follows:

About the TRB AHB70 Access Management Committee

Under the leadership of our new chair, Marc Butorac, the TRB committee is simplifying our subcomittee structure to help meet current needs. This website has information about the 3 committees:

  • Outreach
  • Conference
  • Research

The second edition of the TRB Access Management Manual is undergoing editorial review, and should be published in 2014.

Conference Overview The first Access Management Conference was held in Vail, Colorado on August 1-4, 1993. The conference was sponsored by the Colorado Department of Transportation (CDOT), the Federal Highway Administration (FIIWA), and the Transportation Research Board (TRB). It was attended by over 150 persons from a wide range of transportation disciplines (including engineers, planners, and legal experts) representing federal agencies, state and local departments of transportation, and private consultants.

TRB’s Transportation Research E-Circular E-C151: Modeling Operating Speed is a synthesis of existing operating speed models developed in different regions of the world. The models are grouped according to roadway type. 

Limitations and deficiencies in existing operating speed models and suggestions for future work are also identified. 

Practitioner perspectives on the potential use of speed prediction models in road design practice are provided from both the perspective of the United States and the international community.
