About the NHTS…
• National Study on Passenger Travel– Passenger Travel is 82 percent of all VMT
• Conducted since 1969– 1969, 1977, 1983, 1990, 1995, 2001
• All Travel, All Purposes, All Modes• 2001 NHTS
– Interviewed about 70,000 households– 175,000 Persons– Travel recorded for an entire day
For Each Vehicle:Make Model Age (year)How long owned*
NHTS General Content
For Each Household:Number of peopleNumber of driversNumber of workersNumber of vehiclesIncome
For Each Person:Age GenderDriver statusWorker StatusAnnual Miles
Daily Travel Data:Origin and Destination address (for add-ons)Time trip started and endedDistanceMeans of transportation:
•vehicle type•if household vehicle, which one•if transit, wait time•if transit, access and egress mode*
Detailed purpose*Number of passengers on trip:Most recent trip for non-travelers (date)*
• Descriptive statistics– Households
– People • Drivers and Workers
– Vehicles
– Trips
• Travel Behavior – Mode share distribution
– Travel time, speed, distance,
– Work and Non-Work Travel
• Special Populations– Older Drivers
– Bike and Pedestrian
– People with Disabilities
– New Immigrants
State Involvement
• Statewide Corridor
Planning• MPO Coordination• Statewide Forecasting• Special Populations
Research
NHTS Add-On Program
In 2001, State participation included
– NY,WI, HI, TX, KY
For 2008, the Add-On program elicited tremendous response
– About 85,000 samples (currently)
– FL,GA,SC,NC,VA,NY,WI,CA,IN
– Many MPOs including Maricopa, Pima, Cedar Rapids, Pikes Peak, and Omaha.
