Activity-based approaches to travel demand analysis have gained increasing attention over the past decades. This thesis aims to propose an algorithm that belongs to this field. Its objective is to simulate individual’s daily activity-travel patterns, and to incorporate the interactions among members of particular household. This model uses several tools to simulate the activity patterns. A lot of effort has been dedicated to cluster analysis of activity patterns. The methodology has been studied and an approach that suits this problem is suggested. Decision trees, particularly the CHAID algorithm, are used to take into account the personal and household characteristics.
The individual’s daily activity patterns that carry information about activity participation on a detailed temporal scale are the output of this model. These patterns respect individuals’ constraints that are implicitly embedded. The model was evaluated using data from the Centre County, Pennsylvania that were collected during fall 2002 and spring 2003.
