  1. Impacting Local GovernmentUpdating Functional Classification Using GIS Bentonville, Arkansas September 12, 2013

  2. Presentation Overview • Introduction • Federal-Aid System • Functional Class • Adjusted Urban Area Boundary • Purpose of Project • Methodology – GIS • Proposed Process • Good Practice Steps & Schedule • Questions and Answers

  3. The Federal-Aid System “Federal-Aid highway funds are authorized by Congress to assist the States in providing for construction, reconstruction, and improvement of highways and bridges on eligible Federal-Aid highway routes and for other special purpose programs and projects.”

  4. The Federal-Aid System Arkansas 22,360 miles • State Highways16,220 miles • County Roads 3,780 miles • City Streets2,360 miles

  5. Functional Classification • Importance • Federal-Aid highway funding • Impacts to Roadway Design • Project Prioritization Remember Funding is directly related to the functional classification of a road

  6. Functional Classification

  7. Functional Classification

  8. Functional Classification • Interstate • Other Freeway & Expressway • Other Principal Arterial • Minor Arterial • Major Collector • Minor Collector • Urban Minor Collectors – Yes • Rural Minor Collectors - No

  9. Functional Classification

  10. Adjusted Urban Area Boundary

  11. Adjusted Urban Area Boundary City (Urban) Responsibility TEST

  12. Adjusted Urban Area Boundary County (Rural) Responsibility

  13. Purpose of Project • FHWA requirement to update the urban boundary and functional class of roadways every 10 years. • Update functional classifications due to changes in the urban boundary as a result of the 2010 U.S. Census data. • Re-assess the existing functional classifications and make changes and additions where necessary to the system since 2000.

  14. Methodology • Updating using GIS is a new process • Utilize • ESRI Shapefiles • Geo-Database Files • Learn as we go • Utilize stakeholder Input • Inter-Agency Cooperation

  15. Methodology Proposed Process

  16. MethodologyProposed Process • Assess Need for Additional Functional Classification Changes • Make updates • Meet FHWA mileage % ranges • Prepare Maps or GIS Files for AHTD Evaluation • Work with AHTD during evaluation process • Evaluation process will take some time • Seek FHWA Approval • FHWA is a concerned stakeholder

  17. MethodologyProposed Process • Functional Classification - Triggers • Changes in roadway characteristics or use • New significant roadways • Significant growth (population/traffic) • Extension of existing roadways • Changes in traffic patterns • New schools, industry, or other economic assets

  18. MethodologyProposed Process • Minimize functional class changes along the roadway • A roadway of higher classification should not terminate at a single roadway of a lower classification • There will be exceptions • Maintain Topological Connectivity • Be consistent • Use common sense

  19. MethodologyProposed Process Think Continuity

  20. Good Practice Steps & Schedule • Determining level of functional classification of a roadway can be difficult at times and create uncertainty. • FHWA Functional Classification Manual • FHWA Functional Classification Website (under construction) • AHTD as a resource • Share understanding of the game plan • Encourage & work towards timely delivery of functional classification revisions

  21. Good Practice Steps & Schedule

  22. What If What If: If we do not complete the functional class update, what happens? Answer: AHTD will update the State Highways in your area and leave the existing functional classification at the 2000 level with only minor adjustments. What If: Can functional classification be updated at a later date? Answer: Yes, but only on a case-by-case basis. System-wide update is a one shot deal. What If: Future or proposed un-built roads are included? Answer: There is a 4-year must be built clause and it should already be in the STIP before being added to the functional class file.
