Travel Behavior

• directly linked to land use
• Key components of travel demand behavior are
  activity centersactivitiessocio-economic
  characteristicstime
• Land use changes and travel behavior can greatly
  influence travel demand

Relationship between urban activity systems and
transportation system

Individual Travel Decision Making

• This is called the disaggregate approach
• Where are people going?
• How often are the going?
• What time are they going
• What is the purpose of the trip?
• What mode of transportation are they
  usingautomobile, truck, bus, light rail,
  walking, bicycle

Travel Diaries

• Questionnaire asking related questions to where,
  when, why, how
• With the use of GPS, the need for travel diaries
  may be soon eliminated
• See the following paper

Land Use Classification, trip and purpose using
GIS

Origin Destination Studies

• Very extensive survey of a sample of drivers
• Demographics and questions related to their trip
  purpose, location, time, mode etc.
• Many done in the 1960s, but enough gathered that
  is now not done often
• An interesting paper

Value of Time/Travel Cost

• Different socio-economic groups value time
  differently
• Trip purposes may value trips differently
• Trip purposes by modes may be valued differently
• Logit probability models are constructed from
  findings related to value of time
• Article related to recreational trips and value
  of time

Exercise

• For the last three days, report what purpose,
  when, what route you took trips
• Each individual will report to class after 10
  mintues

Conclusion

• Travel behavior and land use is the building
  blocks for travel demand modeling and
  transportation planning
• The problem is that this changes over time
  and impossible to predict in the future
• Travel behavior is often used in mass
  transportation research, travel demand
  management, corridor congestion managenement,
  energy consumption, etc.
