GIS-Based Tool for Land Use & Transportation Visualization

This project aims to develop a GIS tool for visualizing interactions between land use and transportation, aiding decision-making and public involvement in transit planning. Data collection includes various sources like Miami-Dade County, FDOT, and USGS. The software prototype includes functions for querying land use, socio-economic, and transportation information, as well as evaluating development scenarios and visualizing transportation project sites. Future work involves improving presentation with photos and videos, studying the link between GIS and FSUTMS, and adding decision support functions.

  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
