  10. Indicators T Goal

  11. TRAVEL DEMAND MODEL Land use Travel behavior T System performance Why Use Travel Demand Models • A relationship between transport system and indicators • Access • Purpose • Frequency • Use

  12. Economic, Social, and Environmental Dimensions • Where do they come in to this process? TRAVEL DEMAND MODEL Evaluate progress to goal Indicators System performance Other data

  13. Residential Employment Residential Employment Service Service …through performance indicators • For example: • Commute speed • Land use mix • Transport diversity • Transport equity

  14. Example • Model output = travel times between all points • Indicator: Commute speed • Indicator: Land use mix • Indicator: Transport diversity • Indicator: Equity

  15. Introduction to Travel Demand Modeling • What is a travel demand model • Assignment: Discuss your knowledge • Input data • Trip generation • Trip distribution • Mode choice • Traffic/trip assignment

  16. Demographic Data Step 1: Trip Generation Transportation Network Step 2: Trip Distribution Step 3: Mode Choice Step 4: Trip/ Traffic Assignment Four Step Travel Demand Model (FSTDM)

  17. Trip Generation Questions • How much do people use the transport system? • Why do people use the transport system? • Where can different types of activities be satisfied?

  18. Trip Distribution Questions • Given a location, where do people go to satisfy demand for an activity type?

  19. Mode choice Questions • How do people use the transport system? • What modes do they choose? • How do they react to varying transport service quality?

  20. Trip / Traffic Assignment Questions • How do people use the transport system? • Given a mode, which route do they choose? • Do they satisfy multiple activities in one tour? • Which parts of the transport system do they use? • How do they react to varying transport service quality?

  21. Demographic Data • Autos per household • Income level • Household size
