National Household Travel Survey:

The National Household Travel Survey (NHTS) previously called the Nationwide Personal Transportation Survey (NPTS) serves as the nation's inventory of daily personal travel. It is the only authoritative source of national data on daily trips including purpose of the trip, means of transportation, how long the trip took, day of the week and month, number of people on the trip etc.

In 1995, 2001, 2009, and again in 2017, NYSDOT participated with the Federal Highway Administration as one of several add-on areas. NYSDOT purchased additional household samples to increase the coverage and reliability of the NPTS data for analysis of the travel patterns of residents within New York State; below are the selected survey results for the Ithaca MPO (ITCTC).

  • 1995 NPTS (Released February 1998. Oak Ridge National Laboratory)
