key areas of implementation performance
Key Areas of Implementation Performance
  • Outreach
  • Support for Program: internal and external
  • Strong Implementation Program
  • Models
  • Gain clear understanding of needs of decision makers
  • Develop tool with needs in mind
  • Seek opportunities to use models to address decision makers’ questions
  • Making connections with decision makers will generate seeds of support later
  • Internal support is crucial
  • External support is useful
  • Data collection
strong implementation program
Strong Implementation Program
  • Choose projects wisely
  • Develop skilled staff
  • Use models efficiently, automate
  • Develop effective communication skills
    • Use common language and terminology
    • Educate audience
  • Relate findings in real world terms
    • Tell a logical story, intuitively make sense
    • Identify trade-offs and economic impacts
statewide integrated model
Key criteria

Flexible geographic scale

Truly integrated components

Hybrid formulation

Dynamic activities

Static economy

Activity-based models

Agent-based micro-simulation

“Tight consistency”

Affordable and tractable

Statewide Integrated Model


  • Full integration
  • Explicit representation of economy, land use, and transport
  • Linkages to environ-mental analyses and performance indicators
  • Build on lessons learned from first generation
  • Connect with metropolitan modeling framework
transitional model structure
Economic and demographic (ED)

Production allocation and activity interaction (PI)

Household allocation (HA)

Land development (LD)

Person travel (PT)

Commercial travel (CT)

Transportation supply (TS)









Transitional Model Structure

Spatial activity




  • Connection of economic, real estate, and transport models for the Portland metropolitan area
    • Regional econometric model
    • Residential real estate model
    • Nonresidential real estate model
    • Transportation model
    • GIS accounting and visualization
  • Used for long-range land use and transportation studies
land use scenario developer lusdr
Land Use Scenario DevelopeR (LUSDR)
  • Stochastic microsimulation of household and business location
  • Connects to standard Oregon metropolitan models (JEMnR) and Oregon small urban models (OSUM)
  • Develops land use scenarios for risk analysis and land use and transportation policy testing
  • Is being used in small metropolitan area long-range planning study

Build internal support

Build external support

Identify issues and questions of interest

Statewide collaboration, build bridges to other agencies

Invest in staff

Oregon Advice on Integrated Modeling
oregon advice on integrated modeling1

Think big, start small


Building blocks

Simplest thing that can possibly work

Short development cycles

Design integration with other models & data systems at outset

Design user interface first, models second

Early applications

Build good communications skills for technical staff
