USDOT References NHTS Poverty Brief in the 30 Year Outlook

The USDOT released a draft of a 30 year outlook for the future of transportation Beyond Traffic: Trends and Choices. The draft framework includes major trends, the implications of these trends for each mode of transportation: highways, transit, pedestrian and bicycle, aviation, intercity and freight rail, maritime, and pipeline; a description of a possible future scenario based on the trends and potential policy options based on the implication of these trends. But most importantly, the framework references NHTS and the news brief NHTS Poverty and Transportation. All Americans are invited to share ideas here.

NHTS Academy Module on Vehicle Occupancy

NHTS users have expressed interest in better understanding the analysis of Vehicle Occupancy. As a result, the NHTS team has developed a new NHTS Academy video on Vehicle Occupancy.

  • What is vehicle occupancy?
  • Why is vehicle occupancy of interest?
  • How does the Mileage Method of calculation differ from the Trip Method?
  • Which calculation method does the NHTS use?
  • How does occupancy vary by trip purpose?

Administrator's Excellence in Teamwork Award for NHTS Contributions to C&P Report to Congress

The NHTS was commended for authoring Chapter 1 of the 2013 Status of the Nation's Highways, Bridges, and Transit: Conditions and Performance report to Congress. This effort earned Adella Santos the Administrator's Excellence in Teamwork Award. She was presented with this honor, but recognizes the NHTS team for their many contributions. Associate Administrator of the Federal Highway Administration, David Kim said, "It is a reflection of the tremendous work that was done to write and prepare what is arguably one of the most authoritative reports produced by FHWA." The report is intended to provide decision makers with an objective appraisal of the physical conditions, operational performances, and financing mechanisms of highways, bridges, and transit systems based both on the current state of these systems and on their projected future state under a set of alternative future investment scenarios. This report provides a comprehensive, data-driven background context to support the development and evaluation of legislative, program, and budget options at all levels of government. It also serves as a primary source of information for national and international news media, transportation associations, and industry.

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.
