  1. National Household Travel Survey Highway Information Seminar October 25, 2012 Adella Santos, NHTS Program Manager FHWA, Office of Highway Policy Information

  2. Today’s Talk • Background of the NHTS • NHTS Program • Data Collected • Example of data uses

  3. History • Started in 1969 and periodically conducted every 5 to 7 years. • Collected information on the American Public’s daily travel. • Labeled the “Flagship” of US travel surveys.

  4. NHTS Program Structure NHTS Program National Study Sample Add-On Program Sample

  5. Some uses of NHTS • Measure the amount, type and trends in travel • for national policies and programs • Exposure rates for vehicle or pedestrian exposure (fatalities/million miles of travel) • Trip rates for local transportation planning and air-quality analysis • Research on mobility: elderly, immigrants, school children, low income • Commuting trends and comparison to Journey-to-Work Census Data

  6. The information NHTS can provide: • Congestion: Trends in commute patterns and peak travel • Fleet mix and fuel use: Hybrids, SUVs growth and use • Safety: (drivers, passengers, and pedestrian) • Mobility Issues: Older drivers and non-drivers • Trends in basic travel measures: Changes in the components of VMT: Drivers, workers, vehicles, trip rates auto occupancy

  7. The NHTS Program – Two Components • National Study • Serves the department, congress, and administration with 40 years of trend data • Resource for state and MPOs (forecasting and benchmarking) • Add-On Program • Allows States and MPOs to purchase additional samples for their local area • Program participation allows for state or regional estimates

  8. Add-On Funding Process Add-Ons = State, Local Governments & MPOs • Each Add-On pays for their number of additional samples • FHWA Pooled Fund mechanism • Add-On Funds allocated by: • 90 Percent for data collection and data file delivery • 10 Percent for program management, quality assurance, and data analysis.

  9. 2009 Add-On Participants

  10. Contents of Questionnaire

  11. Trip definition is from one address to another by all modes

  12. Example of Uses • Congestion • Safety • Mobility

  13. Nature of Congestion • Peak Period travel is complex • Commuters are making incidental stops before and after work. • Stopping for different reasons (childcare, coffee, pharmacy, school age drop-offs, groceries, meals) • Incidental stops are during peak time

  14. Non work trips add to Congestion

  15. Non Work Related Travel During Peak Period

  16. 2009-Mandatory Peak travel About 2/3 of AM But About 1/3 PM. Mandatory Mandatory

  17. Approximately 30% of AM and 25% of PM Mandatory trips use an interstate

  18. Safety Speed plays a role Or Types of Vehicles

  19. Average Commute Speeds by MSAs: All modes

  20. Fleet: Distribution of HH Vehicles by Vehicle Age

  21. Mobility: As we age we tend to drive fewer miles.

  22. NHTS: Future Long Distance Travel • Conduct of research is presently underway. • Developing a design for a national long distance survey • Goal is to identify characteristics of current use of the nation’s transportation system for • forecasting demand, • alternative for investment • development of the system and • Assess the effects of legislation on the system.

  23. Next NHTS is Scheduled for 2015 If interested contact:Adella SantosNHTS Program MangerAdella.Santos@dot.gov202-366 5021
