This report presents the results of a number of detailed Iowa access management case studies. Case studies were selected to provide a cross-section of locations and community sizes in Iowa as well as a variety of project types. Projects were analyzed on a before and after basis in terms of traffic safety, traffic operations, and adjacent business vitality. Sources of information used for the case study analysis included: road project files; traffic accident records; state sales tax records; and personal interviews of business owners, business customers, and local officials. Recent access projects in Iowa had significant, positive impacts in terms of traffic safety. The average reduction of annual accidents and accident rates on improved roadways was approximately 40%. Improvements in access management also led to significantly better roadway operations for most case studies. The results from the Iowa case studies presented in this report will be used to develop access management education materials for Iowa transportation professionals and other audiences interested in the impacts of access management.
