• Abstract:
  The Federal Highway Administration (FHWA) originally published the Model Inventory of Roadway Elements – MIRE 1.0 guidance on a set of recommended safety data elements for State departments of transportation (DOTs) in 2010. These elements could support a variety of network and site-specific safety analyses, as well as support the methods introduced in the First Edition of the American Association of State Highway and Transportation Officials’ Highway Safety Manual. In 2017, FHWA updated and expanded the MIRE guidance and introduced the concept of MIRE Fundamental Data Elements (FDEs). These MIRE FDEs include data elements for roadway segments, intersections, and interchange/ramps on non-local paved roads, as well as smaller subsets for local paved and unpaved roads. This case study presents an effort by the Ohio Department of Transportation (ODOT) to 1) develop a digital inventory of intersection locations on all public roads in the State, and 2) collect MIRE FDEs at those intersections to support statewide safety screening and analysis. The intersection inventory will serve several important purposes for ODOT, including meeting Federal data requirements and substantially improving data analysis capabilities. ODOT’s data integration with existing and future data analysis systems and work with FHWA’s Applications of Enterprise Geographic Information Systems for Transportation (AEGIST) pooled fund study will expand intersection safety analysis capabilities throughout the agency.
