Abstract:"National transportation statistics have shown the rise of long-distance, trans-regional commute
(LDC/TRC) in the US. Four societal factors contribute to the trend: increase in dual earner households,
advance in information and communications technologies, new concept of arranging work time weekly,
and people's changing attitude towards travel. In the field of urban transportation planning, commuting
has been studied in individual metropolitan areas in a one-day time frame. LDC/TRC traverse multiple
metros and the commuting behavior cannot be better understood without going beyond the one-day
convention. Studying LDC/TRC corresponds to the growing interest worldwide in planning for
megaregions. Up to date, the phenomenon of weekly commuting has been explored only by a few
European researchers in the fields of geography and sociology.
This study analyzed LDC/TRC using national datasets available in the US. They are American Travel
Survey, National Household Travel Survey, and Census Transportation Planning Package. Further
detailed analyses were conducted for the Texas Triangle megaregion. The national travel surveys are
helpful in portraying large pictures of LDC/TRC but limited in offering insights into LDC/TRC
behavior. Based on the preliminary study, the next phase of the study will conduct qualitative research
by interviewing selected LDC/TRC individuals in the Texas Triangle megaregion."
