Portland, Oregon
3 Tracks
The 1998 National Conference on Access Management, held in Ft. Lauderdale, Florida, from October 4 to October 7, 1998, was sponsored by the Transportation Research Boards Committee on Access Management and the Federal Highway Administration Office of Technology Applications. The Florida Department of Transportation hosted the Conference.

Conference Proceedings The 7th Conference on Access Management was held in Park City, Utah on August 13th to 16th, 2006. This website and Access Management DVD Library 2007 contain most of the presentations from the conference. The conference proceedings are posted on the http://teachamerica.com/accessmanagement.info/2006conference.html . The session topics were chosen to match the Chapters in the TRB Access Management Manual.
Executive Summary
International Conference on Access Management was held in Athens Greece Jun 15-17, 2011
The purpose of this study was to determine whether acquiring additional limited access right-of-way (ROW) at the time an interchange is built and before the surrounding area is subdivided and developed, is in fact cost effective in light of potential costs and benefits. The study methodology included the following: (1) traffic operations analysis of the interchange with varying configurations of signalized access spacing, (2) safety analysis of interchanges with varied access spacing in Florida, and (3) a cost/benefit analysis of acquiring varying amounts of limited access ROW.
This paper discusses how access management techniques have impacted Value Engineering (VE) studies. The following three topics are described and discussed using results from actual VE studies: Diamond interchange footprint; Urban widening (retrofit with median strip); and Left turn lanes on a rural arterial.
The Missouri Department of Transportation (MoDOT) is conducting a group of studies to determine how to improve 200 miles of Interstate 70 between St. Louis and Kansas City. Addressing access within the functional boundary of interchanges is a key element of the project. The paper first briefly reviews I-70 decision making studies and MoDOT's access management guidelines. Attention is then focused on access management and the National Environmental Policy Act (NEPA).
The Wisconsin Department of Transportation (WisDOT) has begun experimenting with new combinations of tools aimed at addressing transportation problems within their community context. The most extensive and deliberate use of these tools is corridor planning. Corridor planning is an approach that is rooted in collaboration with local communities to address all the issues of context that are beyond the purview of the state transportation agency.
The Missouri Department of Transportation has utilized several microsimulation software packages to analyze the impacts of proposed designs, such as interchange footprint and outer road spacing. Traditionally, one of the most difficult aspects of a project has been providing a clear understanding of the final product to the public. This paper discusses the use of visual simulation models to convey access management techniques to the general public.
Sixth National Conference on Access Management, August 29-September 1, 2004, Kansas City, Missouri
The process involved the development of a corridor economic profile, a business inventory and classification study to determine the businesses most likely to be impacted by access changes, a set of detailed business interviews, a business forum, and a business-oriented design charette.
Managing Traffic on Urban Limited Access Facilities. Ingress Through Tolling and Egress to Large Scale Generators as Keys to Relieve Congestion. The Case of Attica Tollway in Athens, Greece
Freeway access management activities have traditionally taken a nominal approach to safety. Acceptable safety performance is presumed to result from attaining some desired interchange or ramp spacing. This approach oversimplifies driver behavior and complex interactions between roadway geometrics, traffic operations, and safety. The objective of this paper is to quantify the relationship between ramp spacing and freeway safety, with safety defined as number of accidents, or accident consequences, by kind and severity, expected to occur during a specified time period.
TRB's Access Management Manual provides technical information on access management techniques, together with information on how access management programs can be effectively developed and administered.

There were several objectives of the project:
This guidebook provides a template for corridor planning that will assist states to better understand the implications of transportation decisions on mobility,
TRBs National Cooperative Highway Research Program (NCHRP) Report 650: Median Intersection Design for Rural High-Speed Divided Highways explores common safety issues at median intersections on rural divided highways, and examines innovative geometric and operational treatments for addressing those issues. The report includes ten case studies that illustrate how various treatments have been applied in the field.
This report classifies access management techniques and presents methods for estimating the safety and operational effects of the different techniques. For some techniques, quantitative assessment was not practical and case studies are presented to demonstrate good and poor practice. This report will be very useful to those developing access guidelines and policy and those analyzing specific access situations.
This digest summarizes findings of National Cooperative Highway Research Program (NCHRP) Project 3-52A, "Impacts of Access-Management Techniques." NCHRP Report 420, "Impacts of Access Management Techniques" (1999), presents relationships between access density and accident rates. This digest uses additional data from Minnesota to confirm these relationships. The digest is organized as follows: Introduction; Problem Statement; Objective and Approach; Background; Results; Comparisons; and Accident Rate Indices.
TRB's NCHRP Synthesis 348: Improving the Safety of Older Road Users examines programs and policies in place across the country to improve the safety and mobility of older road users. The report documents a range of strategies and related programs under way in roadway engineering, driver licensing, public information and education, and enforcement and adjudication.
Access Management Performance Measures for Virginia: A Practical Approach for Public Accountability
In order to develop performance measures to communicate the effect of Virginias access management program, five tasks were performed:
ICF Consulting. Congestion Management Systems: Innovative Practices, Prepared for the New York State Association of MPOs, (August 2005)
The Maricopa Association of Governments (MAG) conducted a survey of Metropolitan Planning Organizations (MPOs) to assess the implementation of access management at the regional level. The intent of the survey was to determine if access management was being implemented at the regional level; what had been implemented; and how implementation was achieved. Survey responses were divided into three categories: all respondents, respondents serving a population of one million or more (population subset), and respondents serving 25 or more member agencies (agency subset).
