of the utility of continuing the trip from that destination. Dellaert et al. (1998) generalized Kitamura's approach to account for multipurpose aspects of the trip chain. Trip chaining is only one aspect of multiday activity /travel patterns. Several models have recently been suggested to predict more comprehensive activity patterns. These models can be differentiated into the older constraints-based models (e.g., Lenntorp 1976), utility-maximizing models (e.g., Recker et al. 1986), rule-based or computational process models (e.g., Golledge et al. 1994, ALBATROSS-Arentze and Timmennans 2000). 6. Conclusions This article has given a very brief overview of spatial choice modeling. Due to the limited available space, we have focused on some of the key modeling approaches, disregarding alternatives (e.g., dynamic models) altogether. If we examine the accomplishments, one cannot escape the conclusion that the models developed over the years have been increasing in complexity. The theoretical underpinnings of the recent activity-based models are much richer than the Markov or gravity models of the 1960s. Moreover, the brief overview indicates that geographers have been using alternative data, such as experimental design data and activity diaries, in addition to the more conventional survey data. integration: a new method for the design and "nalysis of complex multiattribute judgment problems.
