  1. 1. The Impacts of TOD:From Regional Land Use PerspectiveDo Kim, Ph.D.Department of Urban and Regional PlanningCalifornia State Polytechnic University - PomonaJack R. Widmeyer Transportation Research Conference 1
  2. 2. INTRODUCTION
  3. 3. Introduction • This presentation focuses on how Transit Oriented Development (TOD) impacts on future regional land use and transportation conditions. • By comparing with other land use alternatives, this presentation provides quantitative evidences on how much positive impacts TOD can bring. • This presentation also points out a unique land use scenario planning approach, which is a community stakeholder driven process combined with a cutting- edge GIS simulation technology. 3
  4. 4. Project Overview • Land use scenario planning in conjunction with 2035 Long Range Transportation Plan (LRTP) of North Florida Transportation Planning Organization • Exploring alternative land use concepts and the associated long term transportation impacts and opportunities • By Design, a TOD oriented land use alternative is compared with other land use concepts.
  5. 5. Base of Land Use Alternatives • Developing future land use alternatives in the region in order to accommodate projected population and employment growth 2005 Increment 2005-2035 Annual Growth Rate County Population Employment Population Employment Population Employment Clay 184,624 47,374 132,176 25,270 1.84% 1.44% Nassau 67,681 20,213 38,819 10,782 1.52% 1.44% St. Johns 157,981 65,666 168,382 35,027 2.45% 1.44% Duval 855,572 509,112 362,428 271,564 1.18% 1.44% Total 1,262,795 642,365 701,805 342,643 Avg .1.48% Avg. 1.44%
  6. 6. Four Scenarios • Scenario A – Concentric Outer Growth • Scenario B – North-South Centers Growth • Scenario C – Satellite Centers Growth • Scenario D – Transit Centers Growth
  7. 7. Scenario A – Concentric Outer Growth • Outer growth into vacant and undeveloped lands outside the existing urbanized areas • Supporting expanded highway network with limited transit options
  8. 8. Scenario B – North South Centers Growth • Growth in an outward direction away from existing urbanized areas and into the region’s north and southeast quadrants • Supporting north-south commuter rail transit and continued highway investment
  9. 9. Scenario C – Clustered Satellite Centers Growth • Outer growth along key transportation corridors and strong redevelopment strategy in old urban areas • Supporting moderate levels of transits and continued highway investment
  10. 10. Scenario D – Transit Centers Growth • Redevelopment concentrating in major urban areas and development along future commuter rail and other transit • Supporting most robust transit network for the region
  11. 11. SCENARIO BUILDING PROCESS
  12. 12. Place Type Oriented Modeling • Community elements - pedestrian shed • ¼ mile diameter area (40 acres) • Combination of different development types (building types) in the shed

  37. 37. Lessons Learned • Transit Oriented Development can save significant amount of agricultural and environmental lands and also improve traffic flows and air quality. • When TODs are combined with highway development, careful consideration is required in terms of locations and spacing of TODs. • In the case that there is strong infill and redevelopment trends in a region, TODs can be an excellent development option connecting redevelopment hubs and supporting balanced development 37
