Criteria for Evaluation

1
Criteria for Evaluation

• Design exploration capabilities
• Visualization capabilities
• Scoreboard for performance measures and
  scenario evaluation
• Usability and viability for the technician
• Usefulness and benefit for broad audience

2
1. Design Exploration Capabilities

• Iterative scenario development design or plan
  alternatives can be added, modified.
• The tested software uses different design
  approaches, CityCAD is liner,
• CommunityVIZ is iterative

Scenario 1 To Scenario 2t

1. Design Exploration Capabilities

• Compare scenario alternatives to existing
  landscape, environment

CommunityVIZ uses existing spatial data to create
3D representations of existing conditions
allowing side by side comparison between existing
conditions and new scenario/proposals
4
1. Design Exploration Capabilities

• Applicable to context of neighborhood-level
  design and planning.
• All programs use 3D modeling software to augment
  detailed site-level scenario visualization.

Google SketchUp succeeded at providing sufficient
detail to demonstrate the character of station
and neighborhood
level design scenarios while CityCAD creates
scenarios with acceptable detail for early sketch
planning.
5
1. Design Exploration Capabilities

• Fast performance creating and exploring design or
  plan scenarios.
• CityCAD is a rapid sketch-planning tool

6
2. Visualization Capabilities

• Generate 3-D visualization for land use and
  development.
• Powerful modeling programs have a clear
  advantage.

7
2. Visualization Capabilities

• Able to show phased development, change over time
  CC

8
2. Visualization Capabilities

• Adequate realism and detail in representing the
  landscape.

9
2. Visualization Capabilities

• Demonstrates spatial arrangement, proximity to
  amenities. CityCADs proximity measurement

3. Scoreboard for performance measures and
scenario evaluation

• Composite scoring of indicators, determined by
  users goals
• Envision Tomorrow, although extremely data
  hungry, provides nearly limitless impact
  measures.
• Environmental
• Economic
• Infrastructure
• Resources
• Planning Measures
• By land use or building type
• CityCAD CommunityVIZ are also customizable and
  comprehensive in impact measures.

11
3. Scoreboard for performance measures and
scenario evaluation

• Measures and scoring enable comparison of plan
  scenarios
• Envision Tomorrow and CommunityVIZ allow for side
  by side comparison of five scenarios
  simultaneously.
• CityCAD works in a more linear, step-by-step
  modification process were you see impacts only to
  what has just been modified or created. It is
  possible to create scenarios independently of one
  another and compare that way.

12
3. Scoreboard for performance measures and
scenario evaluation

• Tool can model land use and produce indicators of
  outcomes
• All can perform this function at some level, but
  Envision Tomorrows flexibility, level of detail,
  and easy of use make it the clear front runner in
  this category.
• CityCAD is the most black box in this category,
  with the calculations based on information about
  local conditions and internalized formulas,
  resulting in limited capacity for modification.

13
3. Scoreboard for performance measures and
scenario evaluation

• Tool can model fiscal and infrastructure impacts
  and outcomes .
• Infrastructure
• Envision and works on assumptions about
  infrastructure based on land use.
• CommunityVIZ and CityCAD can calculate
  construction and maintenance costs as they relate
  directly to the street/road type.
• Fiscal
• Envision tomorrow has the finest level of detail
  in this category, assessing fiscal impacts down
  to the building level.
