Modeling the relationships between home-work-home activity durations and travel times of workers in Hong Kong

Abstract

The Activity-based approach has been widely accepted as a more realistic alternative to conventional aggregated trip-based travel demand models with better capability to model individual activity-travel choice behaviors. Attention has recently been given to the relationship between home-work-home activity durations and workers' travel times to develop activity-based models to estimate their activity and travel choices for long-term transport planning. The traditional household interview survey data from the Travel Characteristics Survey (TCS) conducted in Hong Kong in 2011 is used in this paper. With this, we assess the effects of travel times (including departure times to and from work) on the activity durations of workers in Hong Kong. On the basis of these findings, an activity-based model is calibrated to quantify the temporal utility functions of the home-work-home activities of workers. Finally, insightful findings on the data analysis and model results are given in conclusions together with recommendations for further study.
