  1. Development of a GIS-Based Tool for Visualizing Land Use-TransportationInteractions & Transit Planning Fang Zhao, Florida International University Scott Burton, Marie York, John O’Brien Florida Atlantic University Jo Penrose, Florida DOT, District 6

  2. Introduction • Link exists between transportation and land uses • Land use planning and transportation planning are not well integrated • Elected officials and the public do not understand models well • A visual approach is needed for decision making and public involvement

  3. Goals and Objectives • Provide information to decision makers and the public concerning transportation investments • Develop a prototype computer visualization tool to study • feasibility • options of technologies • design and implementation issues

  4. Technology Considered • GIS • visualization map based • desktop application • Web GIS • dissemination of information to the public • data sharing among government agencies • Multimedia • photo: site conditions • video: roadway operating conditions

  5. Technologies Considered • Animation • complicated • scaling effect • low resolution • 3D model • complicated, expensive • not feasible except for specific sites and specific projects

  6. Data Collection and Data Sources Data sources include Miami-Dade County, FDOT, and USGS • Miami-Dade County • TAZ (MPO) • Census Tract (ITD, adjusted to base map) • FSUTMS network and inputs/outputs (MPO) • Major roads and detailed streets (ITD) • Libraries, schools, fire stations, hospitals, parks (ITD) • Public well field protection areas (ITD) • Trash centers and land fills (ITD)

  7. Data Collection and Data Sources • Flood zones • Hurricane evacuation zones • Public transit bus routes and stops (ITD) • Land parcels (partially owned by FP&L) • Property tax appraisal databases (TAO) • Building permits (PD) • Land uses (ITD)

  8. Data Collection and Data Sources • FDOT (state roads) • Number of lanes and other RCI data • AADT • LOS • Speed • USGS • DOQQs

  9. Conceptual Framework of VOLUTI

  10. Design of Prototype Software • ArcView based • Customized with Avenue • Predefined queries • Menu driven

  11. Desired Functions • Queries of land use information • Queries of demographic and socioeconomic information • Queries of transportation facilities • Queries of accessibility • Support for making changes in land uses • Support for making changes in transportation system • Evaluation of development projects (scenarios) • Visualization of transportation project sites

  12. View Menu • Theme manager • Imagine background control • Display extent control • Redraw • Clear queries

  13. Land Use Menu • site photos • zoning • vacant land • underutilized land • dwelling units • land use composition • sales price history • assessed values • public facilities

  14. ENVIRONMENT Menu • Flood zones • Public well fields • Trash centers and land fills • Hazardous waste sites

  15. SOCIOECONOMIC Menu • Traffic Analysis Zones • Population statistics • Employment statistics • School enrollment • Additional census statistics in the future

  16. TRANSPORT FACILITY Menu • Display different types of facilities • Display attributes of special interest

  17. ACCESSIBILITY Menu • Currently a simple measure of presence of expressways and major arterials • Future • define major employment and population centers • measure accessibility by travel time

  18. Data Issues • Lack of metadata • Inaccurate data • Incomplete data • Out-of-date data • Lack of historical data (land uses, land prices, transportation projects in digital formats) • Lack of a formal mechanism for data sharing and exchange

  19. Linkage between GIS andFSUTMS • GIS network and model network different • Display model output • Input into model - reevaluate accessibility • transportation improvement • land use change

  20. Technologies • ArcView is easy to use, quick to implement, but has some limitations • Animation • Visualization in 3D

  21. Future Work • Improve presentation by static photos and videos • Support creation of various scenarios • Study linkage between VOLUTI and FSUTMS • Add decision support functions • Complete web implementation • Feedback from users • Study portability of VOLUTI
