Model Minimum Inventory of Roadway Elements (MMIRE)
Safety data are key elements to sound decisions on the design and operation of roadways. Critical safety data include not only crash information, but also roadway inventory, traffic, driver history, and citation/adjudication data. MMIRE includes a listing of roadway inventory and traffic elements essential to safety management and proposes standardized coding for each.
Digital Highway Measurement System (DHM) – For more information, contact Lincoln Cobb, lincoln.cobb@dot.gov
The product of 6 years of research and development by FHWA, DHM is a high-accuracy roadway and roadside data collection vehicle. The DHM vehicle is instrumented with multiple technologies, sensors, and computer analysis capabilities to collect and process raw highway data and produce readily useable, electronic data files. Using information collected on, over, and under the road, DHM enables the user to generate as-built plans, take roadside inventories, and measure pavement surface and subsurface conditions. The website is currently under development.
Highway Safety Information System (HSIS)
HSIS is a multi-state database that contains crash, roadway inventory, and traffic volume data for a select group of States. The participating States were selected based on the quality of data available and their ability to merge data from the various files. The HSIS is used to analyze a large number of safety problems, ranging from the more basic "problem identification" issues to modeling efforts that attempt to predict future accidents from roadway characteristics and traffic factors. The HSIS is used in support of the FHWA safety research program and as input to program and policy decisions. The HSIS is also available to analysts conducting research under the National Cooperative Highway Research Program, university researchers, and others involved in the study of highway safety.
