Abstract

This paper proposes a model for household stop generation and organization that accommodates the ordinal discrete nature of stop-making and incorporates a comprehensive policy-sensitive measure of accessibility.  The model is applied to examine household shopping stop-making behavior using a Boston area household travel survey.  The empirical results provide useful insights into the effect of household characteristics and accessibility to shopping opportunities on shopping stop behavior.  The application of the model is demonstrated by examining the effect of an increase in highway costs and changes in land-use patterns on shopping stop generation and organization.
