Motivation
How do we accommodate growth while maintaining
the quality of life for the 2.6 million people
who already live and work here?

Twin Cities Reality

• Excess capacity
• Resource wasted
• Infrastructure deficit
• Economy braked
• Quality of life degraded
• The tool aims to remove lumps by synchronizing
  land and infrastructure development, regardless
  the situation.

Emerging Needs

• Decreased level of transportation funding
• Existing infrastructure deficit
• Projected regional growth
• Needs for land use and transportation integration
  and optimization
• Needs for scenario building forward planning

Use GIS-T to Synchronize

• Data integrity
• Predefined GIS operations
• Proper topological representation
• Spatial analysis/visualization
• Future of GIS
• Knowledge-based GIS
• Web-based GIS
• GIS integrated with optimization technique
• Integrated urban land and transportation planning

Progress in GIS-T has not caught up with the
growing spatial data availability.

Hypothesized Planning Policy Contexts

• Policy alternatives (e.g., capacity expansion vs.
  demand management),
• budget constraints (e.g., tight vs. loose),
• regional priorities (e.g., private
  transportation-oriented vs. mass
  transit-oriented),
• expansion decision rules (e.g., structured vs.
  unstructured),
• technology perspectives (e.g., ITS-driven vs.
  conventional options)

13
The Iterative Loop Control

• Converge land Infrastructure scenarios
• Provide multiple optimized solutions
• Synchronize land and infrastructure development

14
Summary of Key Functions

• Quantify evaluate infrastructure needs
• Identify locations of transportation improvement
• Identify locations of land development
• Improve accessibility, quality of life, property
  values

15
Summary of Benefits

• Ensure a comprehensive set of strategies to be
  considered
• Future-oriented preventative solutions
• Protect the integrity of land use and
  transportation planning
