Abstract
Household and individual demographics, attributes, and dynamics have significant effects on travel behavior and the overall performance of the transportation system. This study attempts to examine the effects of household demographic changes on the travel attributes of households grouped into several homogeneous lifestyle clusters. With the use of the National Household Travel Survey 2001 data, more than 20 travel attributes including number of auto trips, trips per tour, transit usage, and average commute distance are analyzed. To investigate the impact of changing demographics on household- and individual-level travel attributes, the best-fit distributions for a large set of travel attributes are introduced. Then a detailed comparison between the resulting distributions across different lifestyles and demographics is presented.
