Building on the extensive experience with geographic information systems (GIS), data integration and safety analysis, the University of Wisconsin TOPS Lab developed CurveFinder, a tool to extract horizontal curve location and geometric information automatically from GIS roadway maps. CurveFinder was successfully used in Wisconsin and Iowa. CurveFinder incorporates compatibility with FHWA’s Model Inventory of Roadway Elements (MIRE) curve elements. The CurvePortal is a web interface for extracting horizontal curve location and geometric information automatically from GIS roadway maps. CurvePortal will provide curve data in GIS format for easy integration with existing asset management, roadway inventory, and crash datasets.
