Project Background and Goals

Access management is a process that manages access to land development while seeking to preserve the flow of traffic on the surrounding road system. Sound access management practices can lead to safer roads that provide better service to motorists. In 1996, the Iowa Department of Transportation established an Access Management Task Force as part of its Safety Management System development effort. The Task Force is working with the Center for Transportation Research and Education at Iowa State University and other researchers at the University of Northern Iowa to improve awareness of how access management can lead to safer, better functioning highways, roads, and streets in Iowa.  The Task Force and Research Team are also investigating the effects that access management projects have on local business vitality.

Project Phases and Work Products

The Access Management Awareness Project is divided into four work phases.

Phase I

Completed in October 1996, Phase I was a review of the extensive access management literature.

A report on the current status of access management policies and practices in Iowa is also now available. This report presents the results of a telephone survey of 20 large cities and 11 counties located in metropolitan areas.

Phase II

Phase II involved detailed research into existing access management policies and the safety and traffic flow impacts of specific access management case studies in Iowa. The effect of controlling access on local businesses was also evaluated for selected Iowa case studies.

This phase was completed during the winter of 1997. It resulted in several published reports, including detailed case study documentation, results of opinion surveys of businesses and motorists, and a report on the effect of access management projects on local business trends. An Executive Summary report has also been prepared.

Phase III

Phase III involved the development and dissemination of access management training and education materials for transportation professionals, elected officials, and the general public. Training and education materials included a statewide access management conference, printed materials, multimedia materials, and Internet resources.

Phase IV

Phase IV involved additional research in three more selected case studies in Iowa. This phase also involved the identification of potential future case study locations and production of educational materials for target audiences. Phase IV Final Report (956 kb *pdf file)
