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

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

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)

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
• Possible scales
• Blocks
• Pedestrian sheds
• Place sections
• Places

Designing Community Elements

• Option 1 Use CorPlan Design Module

25
Designing Community Elements

• Option 2 Use design software, such as Sketch
  Up, and import to CorPlan

Design Concept
Underlying lot and building polygons exported to
Corplan
26
Designing Community Elements

• Option 3 Field inventory of existing place

27
Community Element Library

• Library is palette of colors used to paint
  polygons in polygon layer
• Number of differing community elements is
  unlimited

Modification of Allocation

• Remove allocation
• Re-assign to another building type / community
  element
• Modify a community element

Exporting Allocation

• Summarize allocated data by any geographical
  boundary (TAZ or census block) or community
  element
• Export summarized data in DBF for further
  analysis
• 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

Project Overview

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

Community Element Inventory
CE Design Model

• Example City Element
• Mix of uses
• Buildings 2 6 stories
• Prototypes
• Downtown St. Augustine
• Edge of Downtown Jacksonville

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

48
Summary

• Integrative
• Design and data
• Across scales
• Intentional
• User in control of design
• Simulation models can verify
• Informational
• Export to 4 step travel demand models
• Export to fiscal impact / environmental models
