The goal of Access Management is to safely balance access to land development with efficient road and transportation systems. 

Access management is the coordinated planning, regulation, and design of access between roadways and land development. It encompasses a range of methods that promote the efficient and safe movement of people and goods by reducing conflicts on the roadway system and at its interface with other modes of travel.

  • Procurement Managers
  • Road Building and Road Maintenance Companies
  • Traffic Planning and Management Systems
  • ITS and Communications Companies
  • Road Safety Suppliers and Specialists
  • Environmentalists


The aim of this conference is to share information across the spectrum of transportation interest. 

Papers are invited from all areas of Access Management, including (but not limited to):

  • Access Management Policy
  • Standards for Access Management
  • Integrating Land Use and Access
  • Application of Access Management

Whilst Access Management as a concept was initiated in the developed world, contributions from developing countries are especially welcome.  

Abstracts:  No longer than 300 words, briefly describing the problem statement, approach followed, data collection, analysis , results obtained and conclusions reached, are invited.  All papers submitted will be peer reviewed and all accepted papers will be published in the conference proceedings.

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.

Put me out of business

You are going to put me out of business!

This is by far the most common and passionate complaint. Most small business owners pour their life saving into their business. It is their source of income and security for the future. Therefore, they are very protective of their businesses and are afraid of anything which they view as a threat to the viability of their business. Although it is very difficult to persuade these folks that closing a median opening will not significantly impact their business, the following points could be used to try and calm their fears: 

  • Our surveys have shown that median opening modifications had little or no affect on the selections drivers make when doing business. Most drivers are willing to make U-turns to access a business that they have used in the past. 
  • The most heavily affected businesses are convenience-type stores (gas stations, fast food, etc.). However, the median changes do not impact the demand for these items. In fact, some businesses may actually be positively impacted in these cases. While the store may become slightly less attractive to some motorists, it win likely be more attractive to others. 
  • Many motorists avoid businesses where the access is perceived as unsafe. This often occurs along roadways with poor access management and numerous conflicts. Motorists may be more attracted to a sight with less conflicts at its access points. 
  • Our before and after surveys of business owners found that most business owners were not negatively impacted, and in fact, most said that it was not nearly as bad as they had thought it would be. 
  • Most motorists surveyed stated that they liked the median changes and that the changes did not change their shopping habits. 
  • Service industry offices (Doctors, Lawyers, Accountants, etc.) and specialty stores are not generally impacted as their patrons tend to have an allegiance with the owner or service provider.
