4. Land Use Modeling Methods
Agent base modeling – Community Viz
Behavioral approach – Urban Sim
Policy oriented approach – What If?
Land use suitability approach – LUCIS

5. Limitations of Current Methods
Inadequate consideration of site design
Inability to telescope among scales
Black box versus intentional design
Limited visualization

10. Base Polygon (Canvas) Ability to work at differing scales
Development pods – site analysis
Parcels – site to regional analysis
Polygrids – regional / corridor analysis
Community data assigned to polygons
Data describes development characteristics
Data scaled to size of polygon

11. Site Planning Development pods are geographic allocation basis
Quickly test site plan options

12. Regional Analysis Divide region / corridor into equally sized grids
Assign community data to each grid
Grid data summarized by larger polygons (i.e., TAZs)
Sample polygon layer (1/10th acre polygrid)

13. Classifying Polygons
Undevelopable - polygons “masked” and assumed unchanged
Environmental constraints
Rights of way
Newly developed, stable development
Redevelopable - assignments are factored to a portion of development potential
Developable - assignments assigned at full value

14. Classifying Polygons Sample polygon layer (1/10th Acre Polygrid)
Undevelopable existing uses
Developable land
Undevelopable environmental land

17. Community Data
Detailed characteristics of differing building and development types
Data levels
Lots
Community elements
Lot type composites for geography larger than lot
Recommended scales
Blocks – around 10 acres
Pedestrian sheds – around 40 acres
Place sections – around 160 acres
Places – around 640 acres (square mile)

20. Defining Lot Building Types
Any type of building can be defined by data
Lots without buildings can be defined

21. Community Element Data
Lot building data are “building blocks” for areas larger than lots (community elements)
Larger areas based on analysis scales

29. Allocating Community Elements
Step 1 – Select polygons for allocation

30. Allocating Community Elements
Step 2 – Select community element to allocate

31. Allocating Community Elements
Step 3 – Program scales selected community element data to selected area and updates study area database

32. Modification of Allocation
Remove allocation
Re-assign to another building type / community element
Modify a community element

Generate input data for transportation modeling (ZDATA)

38. Exporting Allocation
Step 1 – Select summary level (i.e., traffic analysis zones)
Step 2 – Select area to export
Step 3 – Select fields to export

2035 Jacksonville, FL Long Range Transportation Plan – assess future transportation needs
Scenario planning –test impacts of different development patterns & transportation needs

42. Scenario Workshop Dot map game
Community element dots with differing values provided to participants
Urban
Suburban
Rural
Target population total provided to all groups
Place dots on regional map until target reached

43. Workshop Maps become Scenarios
Group maps differed in growth strategy
Each group described the strategy used to choose and place dots
Maps become basis for scenarios

44. Conversion to GIS Data Dot game maps translated into CorPlan scenarios
Scenarios used the same control total for “apples to apples” comparisons

45. Scenario Comparison
Land use and access comparisons

46. Scenario Comparison
Travel demand comparisons

47. 3D Visualization
Easy to create 3D models based on the community elements were created for key locations in region
Models helped link colors on map with design characteristics
