• Abstract:
  In 2012, The Tennessee Department of Transportation (TDOT) accomplished its initial data collection for its entire roadway network, which includes all interstates, state highways, arterials, collectors, and local roads. With these data, TDOT created a horizontal curve database with approximately 40,000 miles of roadways with curves, which is housed in the Tennessee Roadway Information Management System (TRIMS)—a client-server application that allows TDOT to capture, maintain, and view critical roadway data. TDOT uses the horizontal curve database to provide quick, data-derived answers to public concerns, make data-driven decisions, quantify potential benefits from both systemic and spot improvements, and compare curves with similar characteristics to help prioritize projects.
