Additional Questions[edit | edit source]

  1. What are the different kinds of models for trip distribution? How do they differ?
  2. What factors do conventional Trip Distribution models neglect?
  3. In a day, how many minutes are spent traveling for the average person, traveling to work? Why might this be stable, not stable?
  4. Do travelers have a travel time tolerance or a travel time budget?
  5. What affects travel impedance?
  6. If impedance increases, will willingness to travel increase or decrease? Is a person more likely to travel to a closer place or a farther place?
  7. Why does willingness to travel have a negative exponential form?
  8. Briefly describe the gravity model? How might the gravity model be extended to depend on more than just size (opportunities) and distance (impedance)?
  9. Why is balancing a matrix an iterative procedure?
  10. What importance does impedance play in balancing iterations
  11. Give two functions of impedance (f(Cij)) used in gravity models.
  12. How do you calculate impedance between zones?
  13. What is congested travel time?
  14. Conventional trip distribution models are estimated for which mode?
  15. How is trip distribution applied?
  16. What can a trip distribution curve tell you about maximum and average trip times and willingness to take trips?
  17. What factors are multiplied to give a resulting trip distribution curve
