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
![Page 3: Fang Zhao, Florida International University Scott Burton, Marie York, John O’Brien](https://reader030.vdocuments.net/reader030/viewer/2022033107/56814689550346895db3ab1b/html5/thumbnails/3.jpg)
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
![Page 4: Fang Zhao, Florida International University Scott Burton, Marie York, John O’Brien](https://reader030.vdocuments.net/reader030/viewer/2022033107/56814689550346895db3ab1b/html5/thumbnails/4.jpg)
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
![Page 5: Fang Zhao, Florida International University Scott Burton, Marie York, John O’Brien](https://reader030.vdocuments.net/reader030/viewer/2022033107/56814689550346895db3ab1b/html5/thumbnails/5.jpg)
Technologies Considered
Animation– complicated– scaling effect– low resolution
3D model– complicated, expensive– not feasible except for specific sites and
specific projects

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Lack of metadata Inaccurate data Incomplete data Out-of-date data Lack of historical data (land uses, land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
![Page 42: Fang Zhao, Florida International University Scott Burton, Marie York, John O’Brien](https://reader030.vdocuments.net/reader030/viewer/2022033107/56814689550346895db3ab1b/html5/thumbnails/42.jpg)
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
