ABSTRACT

Travel is derived demand for activity, so it is necessary to analyze activity-travel behavior. In particular, it should be identified interrelationships among major components of activities, such as activity type, activity duration and travel mode. Therefore, this study is to identify impacts of activity factors on travel mode choice using the 2006 Household Travel Survey Data in Seoul, focusing on discretionary activities (such as shopping and leisure), through descriptive analysis techniques such as one-way ANOVA tests and chi-squared tests, and advanced discrete choice models (mixed logit models) by activity type. Our results show that activity duration statistically significantly affect travel mode choice and their impacts are different by activity type. In addition, significant variables of the models are different by activity type. It is also found that heterogeneous characteristics of travel time and travel costs exist in the models but they are different by activity type. Overall, our findings are able to contribute developing our activity-based models for travel demand forecast comprehensively by identifying interrelationships between major components of activities.
