2015 NHTS Contract Awarded

The FHWA NHTS Program has awarded the 2015 NHTS contract to Westat of Rockville, Maryland. Westat had been the data collection firm that conducted the NHTS in 2001 and 2009.

In the 2015 survey, the national sample will remain at 26,000 while the Add-on Program is estimated at about 54,000 providing a total sample size of about 80,000 households surveyed. FHWA continues to recruit Add-on jurisdictions for the next few months and potential Add-ons should contact Adella Santos at Adella.santos@dot.gov. Also, see the Pooled Fund project page for additional information.

Westat will incorporate a new survey design that includes an Address Based Sample frame using mixed data collection modes. The use of mixed data collection modes such as mail, Internet, GPS and telephone along with incentives is designed to increase respondent participation. Data collection is planned to tentatively start in autumn of 2015 and will continue for a full year.

New NHTS Brief: Mobility Challenges for Households in Poverty

The NHTS team has released a news brief concerning the mobility challenges for U.S. households in poverty. As the second highest household expenditure, transportation costs can have a disproportionately negative impact on lower income households. As a result, 2009 NHTS data has revealed that low income households have higher rates of carpooling, biking and walking. Additionally, low income households have lower rates of vehicle ownership as well as a shorter average daily radius of travel.

2010 Census Boundary Update for 2009 NHTS Now Available

At the time of the 2009 NHTS release, the 2010 Census data had not yet been made available. Therefore, all geocoding was performed with Census-defined areas using 2000 Census definitions. This 2010 Census Boundary Update adds geographic variables based on 2010 Census definitions, and in so doing will build a bridge to the 2015 NHTS. The Census has updated Metropolitan Area and Urban Area definitions, which are reflected in the new 2009 NHTS variables. The 2010 geocoded variables along with supporting documentation can now be found in the NHTS Data Center. Also see the new Academy module.
