 Philip Demosthenes

Access Program Framework

Internationally, an access management program framework will vary by type of government, culture and established preferences in roadway design and traffic engineering. Mr. Demosthenes will use personal experiences from the USA, Greece, and Dubai and Abu Dhabi of the United Arab Emirates (U.AE.) to present and discuss some universal access management issues and principles for agency programs.

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.

The purpose of the Alabama Department of Transportation (ALDOT) Access Management Manual is to set out standards for managing access to and from state roads and highways.

Goals of access management include:

  • protecting the health, safety and welfare of the public
  • maintaining the highway rights-of-way
  • preserving the functional level of state roads and highways while meeting the needs of the motoring public

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.

Benefit-and-Cost Analysis of Strategic Acquisition of Limited Access Right-of-Way near Interchanges

up
Click here if you liked this information

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.

Access Management and NEPA: MoDOT's Experience with the I-70 Second Tier Studies

up
Click here if you liked this information

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).

Corridor Planning in Wisconsin: A Work in Progress

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.

Use of MicroSimulation to Convey Access Management Techniques

up
Click here if you liked this information

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.

Performance-Based Safety Evaluation of Requests for New Access or Modifications to Existing Access on Freeways

up
Click here if you liked this information

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.

What's New

The www.accessmanagement.info website has been completely restructured from the ground up. It is now built on a Drupal Engine as a Content Management System, which simply means that every document, presentation, article, and research statement is a separate item that can be found on the website. You can find content by selecting links, or by using the advanced search tools. There are many more documents that have been added in the past year.

  • Need to involve a multi-disciplinary management level team in each district

  • Communication between all parties is critical throughout the process

  • Florida DOT staff will use creativity and flexibility to resolve issues

 

Some Closing Thoughts

  • Look for solutions within your organization

  • We found a model process in one of our districts.
