Abstract:The research on intermodal transportation is vast. However, most efforts have focused on freight transportation. There is much less research on intermodal passenger transportation—largely due to lack of a comprehensive dataset for effectively studying it [1]. It is essential to understand passenger uses of the intermodal transportation system because passengers are the biggest users of transportation systems, and passenger benefits are one of the important factors, if not the most important factor, in transportation planning and decision-making. This research examines the geographic, demographic, and socioeconomic variations of passenger intermodal transportation usage by analyzing the 2009 National Household Travel Survey data. This study presents descriptive statistics of long and short trips, mode types, and trip purposes, and explores the relationship between different intermodal measures and geographic, demographic and socioeconomic factors. Results indicate significant differences in passenger intermodal transportation usage by age, gender, race/ethnicity, educational attainment, employment, income, and metro status. Decision-makers, transportation planners, and the public can use these insights to better understand and promote efficient passenger intermodal transportation systems.
