Incorporating Long-distance Travel into Transportation Planning in the United States


Lisa Aultman-Hall, Vermont Associate Director, National Center for Sustainable Transportation

For over 25 years, Dr. Aultman-Hall’s research program has focused on innovative travel data collection. She has recently focused on long-distance intercity travel but remains committed to work in bicycle transportation, electric vehicle adoption and system resiliency especially as it relates to planning for climate adaptation. Dr. Aultman-Hall enjoys a wide range of teaching duties at the University of Vermont including first year design, the third year introduction to transportation engineering and several interdisciplinary graduate sustainable transportation systems classes.  Dr. Aultman-Hall is co-Director of the UVM Transportation Research Center, a center she founded in 2006. She is the Vermont Associate Director of the National Center for Sustainable Transportation (NCST), a USDOT UTC program led by UC Davis.  Dr. Aultman-Hall is active with the Transportation Research Board of the National Academies including chairing a task force planning the 2018 National Household Transportation Survey (NHTS) Conference, and chairing the National Transportation Data Committee. She recently founded a new TRB sub-committee on long distance and inter-city travel.

Long-distance intercity travel has vexed transportation planners and modelers for a long time.  The last comprehensive one-year long-distance national travel survey in the United States was conducted in 1995, while the 2001 National Household Transportation Survey (NHTS) and the 2013 California Household Travel Survey included large supplemental surveys covering 3-months and 8-weeks respectively.   Long-distance travel is undertaken by surface and air modes on a global scale beyond the typical boundaries of a regional or state travel demand model.  Yet long-distance travel represents a significant proportion of passengers miles in the US (possibly 30%) and is growing in aggregate and as a proportion.  Long-distance travel demands attention from planners and the first step is advancing the ways we measure it.  This webinar outlines a recent NCST white paper by Dr. Aultman-Hall and covers the following topics:

1. What Exactly is Long-distance Travel?

2. How has Long-distance Travel Demand changed over Time

3. How is Long-distance Travel related to Sustainability: Emissions, Economy and Equity

4. Prior Long-Distance Travel Research

5. A Framework for Moving Forward with Long-Distance Travel Data Collection
