The Role of GIS in Transportation Planning Kevin Damron, P.E. - Deputy State Highway Engineer, Project Development Keith Dotson – Systems Consultant IT Specialist, Division of Planning KYTC Transportation GIS Conference March 29, 2012
Input –Ingredients of a Successful Planning Process • Three Parts: • Local Officials Input • Public Input • 3. Engineering Input
Are all Needs Good Projects ??? Needs Planning Process . . Recommended Projects . Funded Highway Plan
DTP District Transportation Plans • Set Planning Goals and Objectives for Each District • Identify transportation system needs • -Highway District Office • -MPO • -ADD • Compare needs against existing projects • -Current Highway Plan • -HSIP • -Maintenance • Prepare and prioritize manageable list of projects to carry forward
DTP District Transportation Plans • 1st Round of District Meetings • Set objectives • Identified needs geographically • Identified existing projects • 2nd Round of District Meetings • Identified needs not currently on UNL • Completed and re-evaluated cost estimates • Aligned Goals and Objectives with each project • Unscheduled Project List (UPL) • -Recommended Top 30 Prioritized Projects
Input for Recommended Six Year Highway Plan Wish to Unscheduled Needs (UNL) to Unscheduled Projects (UPL) to 6 Year Highway Plan
DTP District Transportation Plans Primary Tool for Evaluation Was an Interactive Data Map
The Role of GIS in Transportation Planning Keith Dotson – Systems Consultant IT Specialist, Division of Planning KYTC Transportation GIS Conference March 29, 2012
DTP District Transportation Plans • The Interactive Data Map shows the following needs: • High Crash Locations • Congested stretches of roadway (High V/C) • Tight curves, narrow lanes and shoulders • Steep Grades and Lack of Sight Distance • Lack of Passing opportunities • High Maintenance Locations (Rockfall and Landslide) • Functionally Obsolete and Structurally Deficient Bridges
Major issues reviewed with the District Transportation Plan Map • Critical Rate Factors • Congestion • Truck % • Roadway Geometry Deficiencies • Typical problems with Interstates and Parkways and Other Principal Arterials • Truck % • Accidents • Congestion • Typical Problems with Minor Arterials and Major Collectors • Accidents • Roadway Geometry Deficiencies
These slides after this point are slides that Keith Dotson will review to see if he will use in his part of the presentation.
DTP District Transportation Plans • The IMS also shows: • Highway Plan Projects • Projects from the Unscheduled Needs List • This GIS Tool allowed District personnel to visually compare needs against existing projects
