Enhancing Statewide Public Road Centerline Data for Transportation Efficiency

The goal of the Statewide Centerline Project is to develop and maintain a comprehensive, up-to-date public road centerline across the state. This initiative ensures accurate mileage for local governments and facilitates efficient statewide road inventory. It aims to build strong relationships with local agencies and foster a cooperative environment. Identifying and resolving issues such as outdated or inaccurate centerlines, road ownership disputes, and topological errors are critical to the project's success. Collaboration and shared data from partners are essential for improvement.

  2. Statewide Centerline Project

  3. Project Goals • Develop a complete statewide public road centerline • Keep the centerline Up-To-Date • Ensure accurate Local Government mileage • Ensure efficient statewide road inventory • Build relationships with Local Agencies • Help foster a cooperative environment

  4. Centerline Data Issues • Roads Extending Beyond or Stopping Short of County Boundary • Topological Errors (Overlapping & Intersecting Road Segments, Dangles) • County vs. City Ownership • Out-of-Date Centerlines • Bad Centerline Geometry • Inaccurate Attribution • Erroneously Coded Roads • Unresolved “Public” and “Unknown” Roads

  5. Out-of-Date Centerline The Centennial Olympic Park Vicinity

  6. Updated Centerline The Centennial Olympic Park Vicinity

  7. Where Are We? • As of June 28, 2013 • 120 Complete • 39 In Progress

  8. How Can You Help? • Provide Digital (GIS) Street, Boundary and Parcel Data • Share Street Attribute Data • Identify Road Ownership • Resolve Boundary Road Issues • Be Available To OTD For Consultations Via Phone, E-Mail or Meetings • Work With OTD and Neighboring Agencies To Resolve Conflicts

  9. 2010 Urban Area Boundary Project Began Summer 2012

  10. Urban and Rural Classification • After each decennial census, the Census Bureau identifies and classifies urban and rural areas. • The Census Bureau identifies urban and rural areas solely for the purpose of tabulating and presenting statistical data. • 1906 - Urban areas of at least 2,500 people • 1950 - Urbanized areas of 50,000 or more people • 2000 • Urban places of at least 2,500 people were identified outside urbanized areas. • Urban clusters of 2,500 - 49,999 were defined

  11. Atlanta 1990 Census Atlanta 2000 Census Atlanta 2000 Federal-Aid 2000 Atlanta Federal-Aid Urban Area Boundary • FHWA "adjusted" or "smoothed" Urbanized Areas and Small Urban Areas that are used for transportation planning purposes • Expands Census boundary to define boundaries to better reflect local conditions.
