This paper introduces an approach to developing activity-based models from stated preference data. We focus on activity behavior as a multi-facet choice process to decide where and in what sequence to conduct activities, i.e., choice of destination and choice of stop pattern. A design strategy is developed to generate choice experiments that allow the estimation of multi-facet models of activity behavior. The results of an empirical application are reported. The experience and results obtained indicate that the proposed approach does provide a stated preference alternative to the revealed preference approach in developing multi-facet models of activity behavior.

Over the past decades, dierent activity-based models have been reported in the literature. Examples include models for enumerating feasible alternative schedules (for example, ÔPESASPÕ, Lenntorp, 1976; ÔCARLAÕ, Jones et al., 1983); discrete choice-based models (such as, ÔSTARCHILDÕ Recker et al., 1986a,b; Adler and Ben-Akiva, 1979; Damm and Lerman, 1981; Van der Hoorn, 1983; Ben-Akiva and Bowman, 1995; Bhat and Singh, 1999); and models for generating activity schedules (such as, ÔSCHEDULERÕ,G arling et al., 1989; ÔSMASHÕ, Transportation Research Part A 34 (2000) 625±643 www.elsevier.com/locate/tra * Corresponding author.
