1 Use GIS-T to Synchronize Land and Infrastructure Development Principle Investigator: Yingling Fan Humphrey Institute of Public Affairs Co-Investigator: David Levinson and Chen-Fu Liao Department of Civil Engineering

2 Motivation 2 How do we accommodate growth while maintaining the quality of life for the 2.6 million people who already live and work here?

3 Twin Cities Reality 3 Time Infrastructure Demand Supply Excess Capacity Infrastructure Deficit 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.

4 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 4

5 Synchronize Land & Infrastructure Development 5

6 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 6 Progress in GIS-T has not caught up with the growing spatial data availability.

7 LSCM Land Supply and Capacity Monitoring A perpetual, event-driven system 7 Land Supply and Market Database Buildable Land Supply Inventory Estimates of Development Capacity Suitability Analysis Land parcels, Service areas, Zoning/plan designations, Government jurisdictions, Building permits, Annexations, Subdivisions, Sales Vacant Partially utilized Underutilized Vacant land capacity Infill capacity Redevelopment capacity

8 Land Use KBES Knowledge-based expert system 8 Estimates of Development Capacity Pop/Econ Forecasts Estimates of Space Requirements Efficient Future Urban Form Minimum Travel Growth Scenario Fuzzy Decision Tree

9 Minimum Travel Approach 9 Shopping Center Home Workplace Childrens School Gym Club Household relocation –Base upon existing and proposed urban form and transportation network Optimum

10 10 Residential Patterns ObservedOptimum Use expansion weight; N=318,966 households

11 TINA Transportation Infrastructure Needs Assessment 11 Future Urban Form Existing Transportation Networks Report on Infrastructure Deficit Mobility & Accessibility Evaluation Future Travel Demand Travel Demand Forecasting Multi-modal network layers Traffic counts dataset Travel time matrices Travel behavior survey datasets

12 Infrastructure SONG/3 System of Network Growth 12 Report on Infrastructure Deficit Hypothesized Planning & Policy Contexts Future Transportation Networks Network Growth Modeling 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 13 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 14

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 15
