TY - JOUR PY - 2016// TI - A user equilibrium model for combined activity-travel choice under prospect theoretical mechanisms of decision-making under uncertainty JO - Transportmetrica A: transport science A1 - Li, Qing A1 - Liao, Feixiong A1 - Timmermans, Harry J. P. A1 - Zhou, Jing SP - 629 EP - 649 VL - 12 IS - 7 N2 - Rather than considering single trips as the unit of analysis, the activity-based modeling paradigm of travel demand analysis has led to reconceptualizations and innovations in traffic flow models by focusing on complete daily activity-travel patterns. The vast majority of these travel demand and traffic flow models have either implicitly or explicitly assumed that travelers choose between alternatives by maximizing their utility under a deterministic representation of the choice alternatives. While this behavioral assumption leads to tractable, easy-to-apply models, the validity of the assumption largely went untested. This paper investigates the user equilibrium of activity-travel patterns under uncertainty from the perspective of prospect theory. A formulation of the static activity-based user equilibrium model is proposed. In particular, we adopt the concept of a multi-state supernetwork to represent the choice space of activity-travel patterns. A numerical example using hypothetical scenarios is presented to illustrate the proposed model and solution algorithm.
