This report presents a study on the influences of select cross-sectional-related design elements (specifically median configurations and bicycle
lanes) and their impact on crash severity and type, as well as the associated driver gap acceptance for turning maneuvers at midblock driveway
locations on urban arterials. The primary goal of this proposed research is to better understand how the median and bicycle lane configurations
can influence safety and operations at driveway locations.

TRB’s National Cooperative Highway Research Program (NCHRP) Report 780: Design Guidance For Intersection Auxiliary Lanes expands on guidance provided in A Policy on Geometric Design of Highways and Streets (the Green Book), published by the American Association of State Highway and Transportation Officials (AASHTO). This report highlights information regarding bypass lanes, channelized right-turn lanes, deceleration and taper length, design and capacity of multiple left-turn lanes, and alternative intersection designs.

The Mid-Year meeting for the ABJ95 Access Management Committee will be held in Salt Lake City during the Symposium on Alternative Intersection and Interchange Design on July 20-23, 2014 in Salt Lake City, Utah.
The symposium will explore a wide variety of new intersection and interchange configurations that have shown promise in improving traffic operations for all users, reducing crashes, and saving money.
The Access Management Committee meetings will be held on Sunday, July 20th from 1 to 6 p.m. The specific schedule is as follows:

Did you know that 2014 is the 20th year of the Access Committee. We were a subcommittee (1990?) with Ron Giguere as chair until December 1993. With the success of the committee, including new research NCHRP 391 (Herb, Frank), the Vail 1993 conference, and more scheduled on our plate, the executive committee granted us full committee status with Ron as chairman. The charter members of the committee all received their appointments in April 1994.
The Second International Conference on Access Management will be held September 25-27, 2014 in Shanghai, China. The TRB committee representatives are in Shanghai, preparing to learn from the symposium, and share our experiences with the international participants.
Fourth National Conference on Access Management
August 13-16, 2000
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.
A Compendium of Papers from the 2nd National Conference on Access Management

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.

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.
