Abstract:Safety data provide the key to making sound decisions on the design and operation of roadways, but deficiencies in many States’ safety databases do not allow for good decisionmaking. The Federal Highway Administration, American Association of State Highway and Transportation Officials, and the National Cooperative Highway Research Program sponsored a scanning study of how agencies in the Netherlands, Germany, and Australia develop and use traffic safety information systems. That scan produced a report that included recommendations for advancing safety themes in the areas of strategy, efficiency, and utility. A recently completed follow-on effort built on the scan team’s final report and draft implementation plan by reviewing in detail the strategies suggested, providing action-related details to some of the critical strategies, and adding new strategies to help reach the team’s goals. As noted in that White Paper, while considerable attention and effort has been devoted to the improvement in crash data, one of the primary safety databases, much less effort has been devoted to improvements in the second primary safety database—roadway inventory and traffic data. One of the five critical strategies detailed there involved improving safety data by defining good inventory data, and specifically recommended the development of a Model Minimum Inventory of Roadway Element (MMIRE) that would define the critical inventory and traffic data elements needed by State and local jurisdictions to meet current safety analysis needs and data needs arising from a new generation of safety analysis tools. This current report presents a proposed MMIRE and documents the development process, which included review of the proposed MMIRE elements in a workshop of safety data experts. A listing of high-priority and supplemental inventory and traffic elements are presented, along with proposed coding for each element.
