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
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
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
Technologies Considered
Animation– complicated– scaling effect– low resolution
3D model– complicated, expensive– not feasible except for specific sites and
specific projects
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)
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)
Data Collection and Data Sources
FDOT (state roads)– Number of lanes and other RCI data– AADT– LOS– Speed
USGS– DOQQs
Conceptual Framework of VOLUTI
Design of Prototype Software
ArcView based Customized with Avenue Predefined queries Menu driven
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
View Menu
Theme manager Imagine background control Display extent control Redraw Clear queries
Land Use Menu
site photos zoning vacant land underutilized land dwelling units land use composition sales price history assessed values public facilities
ENVIRONMENT Menu
Flood zones Public well fields Trash centers and land fills Hazardous waste sites
SOCIOECONOMIC Menu
Traffic Analysis Zones Population statistics Employment statistics School enrollment Additional census
statistics in the future
TRANSPORT FACILITY Menu
Display different types of facilities Display attributes of special
interest
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
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
Linkage between GIS and FSUTMS
GIS network and model network different Display model output Input into model - reevaluate accessibility
– transportation improvement– land use change
Technologies
ArcView is easy to use, quick to implement, but has some limitations
Animation Visualization in 3D
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
