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
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?
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.
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
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.
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
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
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 Residential Patterns ObservedOptimum Use expansion weight; N=318,966 households
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
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)
The Iterative Loop Control 13 Converge land & Infrastructure scenarios Provide multiple optimized solutions Synchronize land and infrastructure development
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
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
