Computational-Process Modelling of Travel Decisions: Review and Conceptual Analysis
Travel behavior entails several interrelated decisions made by people, as well as the execution of routines not preceded by deliberate decisions. Furthermore, travel decisions are dependent on choices to participate in activities. After a brief review of research aiming at describing activity/travel patterns and approaches in which activity/travel decisions are modelled by means of discrete-choice modelling techniques, a conceptual framework is proposed as a background to an evaluation of several computational-process models. Further needed developments of these models are discussed, as well as the use of geographical information systems in their operationalization and application to traffic planning.
