INTRODUCTION
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
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.
Base of Land Use Alternatives
   • Developing future land use alternatives in the region
     in order to accommodate projected population and
     employment growth

Four Scenarios




  •   Scenario A – Concentric Outer Growth
  •   Scenario B – North-South Centers Growth
  •   Scenario C – Satellite Centers Growth
  •   Scenario D – Transit Centers Growth
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
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
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
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
SCENARIO BUILDING PROCESS

Scenarios by Participants
From Chips to Data
  • Converting allocated chips by the public to GIS data
    by CorPlan
  • Land use / transportation planners interpreted chips
    and perform minor modification in order to make
    the allocations fit in areas
Building Type Modeling




 Any types of buildings can be modeled, even
 parcel without a building like park or parking lot

SUMMARY
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
