  7. Abstract:
  8. Individuals have been regarded as independent decision makers in the majority of transportation analysis. However, individual behaviors are usually affected by the interactions between the members in group decisions; and consequently, individual decision making paradigm could result in less-accurate predictions. Besides, as the data used for travel demand modeling typically comes from household level surveys, the idea of random sampling holds at household level and not the individual; and therefore, individual information would not be consistent with the theory of the discrete choice models when the household is the actual sampling unit. The present paper aims at modeling the way that parents accompany the children on their school trips, in dual-worker households with at least one under-18-year-old student. Two modeling approach are adopted to compare accuracy of a group decision modeling method versus a conventional individual framework. The results indicate that more than 25 percent (20 percent) of the correct predictions will be missed in trips to (from) school, when the conventional individual decision making procedure is adopted rather than the group decision making paradigm. This underscores the significance of implementing group decision making paradigms when the context requires
