Computational-Process Modelling of Household Travel Decisions Using a Geographical Information System

Household travel behavior entails interdependent deliberate decisions, as well as the execution of routines not preceded by deliberate decisions. Furthermore, travel decisions are dependent on choices to participate in activities. Because of the complexity of the decision-making process in which individuals are engaged, computational-process models (CPMs) are promising means of implementing behavioral principles which unlike other disaggregate modelling approaches do not rely on a utility-maximizing framework. A conceptual framework is proposed as the basis of a CPM interfaced with the geographical information system ARC/INFO. How to model households' travel behavior is illustrated in a case study of a single household in which one member started telecommuting.
