Travel‐Time Constraints on Destination‐Choice Sets

Modeling constrained destination choice for shopping: a GIS-based, time-geographic approach

“…Space-time constrained destination choice modeling is of particular importance to market analysts, location analysts, and transportation planners who predict the share in alternatives by discrete choice models (Thill and Horowitz, 1997a). In the future, more constraints can be imposed on the universal choice set to define a more restrictive and realistic choice set.…”

“…Available individual choice sets vary from person to person, depending on the objective built environment and the subjective personal perception/preference (Ben-Akiva and Boccara, 1995). The idea of the two-stage discrete choice model has been adopted by transportation studies ranging from mode choice to residential location choice to accessibility assessment (e.g., BenAkiva and Boccara, 1995;Cascetta et al, 2007;Gliebe and Koppelman, 2005;Pellegrini et al, 1997;Swait and Ben-Akiva, 1987;Thill and Horowitz, 1997a;Zhang, 2006). A universally generated choice set that does not reflect variations in individuals' alternatives is a form of choice set misspecification that can lead to inconsistent parameter estimates (Williams and Ortúzar, 1982).…”

“…The model assigns non-negative probabilities to all alternatives in the universal choice set including those not in an individual's true choice set. As a result, it introduces biases in parameter estimation of the utility function, which leads to inaccurate predictions (Arentze and Timmermans, 2005;Kwan and Hong, 1998;Landau et al, 1982;Pellegrini et al, 1997;Thill, 1992;Thill andHorowitz, 1997a, 1997b;Williams and Ortúzar, 1982) and thus erroneous interpretations of human behavior (Thill, 1992;Thill and Horowitz, 1997a). Pellegrini et al (1997), for example, adopted a baseline of 14 stores, and compared it with choice sets from 3 to 13 stores.…”

An Empirically Based Implementation and Evaluation of a Hierarchical Model for Commuting Flows. 一种基于经验的层状通勤流模型实现与评估

“…Analyses that demonstrate how the misspecification of choice sets may produce misleading parameter estimates and predictions can be found in Thill (1992), Pellegrini, Fotheringham, and Lin (1997), and Thill and Horowitz (1997). Many of the spatial interaction studies dealing explicitly with the problem of restricted choice sets are along lines suggested by Manski (1977), with a probabilistic choice set generation.…”

Calibration and Test of a Discrete Choice Model with Endogenous Choice Sets

“…Random-constraints models (Swait andBen-Akiva 1987a, 1987b) use probabilistic constraints to derive a family of parametric choice set models. See also Boccara (1989) and Thill and Horowitz (1997).…”
