• Framework
  • Long term and short term decisions create feedback loops
  • Model this complex process into a feasible set of choices
• Trip Based
  • 4-step model, each trip is a connection between an origin and destination
  • Typical purposes are HBW, HBS, HBO, NHB
  • Limitations of this approach
• Tour Based
  • Chain trips into tours
  • Lacks an integrated schedule pattern
  • Doesn't integrate with time (toll schedule, school schedule)
• Activity Based
  • Travel is derived from activities
  • Tours are independent
  • People face time and space constraint to limit their activities
  • Activity and travel decisions are made in context of the overall schedule
  • Activity pattern -> primary tours -> secondary tours
  • Limitation being that a large choice set can result in unrealistic behavior, and high computation requirement
