About the research

This study designed and developed a coordinated database to provide a graphic link to many relevant datasets at the Iowa Department of Transportation (DOT), so that policy makers and managers can consider multiple functional areas and analyze resulting implications when making decisions. In order to support decision-making at the Iowa DOT, this database combines information from the management systems including Pavement, Bridge, Safety, Congestion, Public Transportation, Intermodal, Traffic Monitoring, and Maintenance. Further objectives of the study effort were to provide all information in a user friendly environment with easy access, to build on other research and database efforts, to evaluate mechanisms for long term support of the database, and to supply a decision-making tool not currently available.
