About the NPTS

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.

NYSDOT Add-on sample

In 1995 and again in 2001, the New York State Department of Transportation participated with Federal Highway Administration as one of several add-on areas. That is, 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. The 1995 survey was conducted from May 1995 to July 1996, the 2001 survey from April 2000 to May 2001.

Journey To Work (JTW)

The journey to work and related questions are asked on the decennial census long form. In 1990 these data appear in Census Summary tape File #3 (STF3) and in 2000 on Census Summary File #3 (SF3). Tabulations, called the 1990 and the 2000 "Census Transportation Planning Package (CTPP)" were created for transportation analysts from these files. The CTPP has three components, a residential summary, a work place summary and a flow based summary. Most of the questions received regarding Journey to Work have been focused on the mode used and the average travel time. To this end, two interactive databases have been developed to allow users to select residence origin(s) and workplace destination(s) at the county or place level and obtain residence or workplace summaries for mode used and average travel time to work.

The 1990 application is based on the 1990 CTPP Part C, means of transportation to work table which did not contain the field “work at home.” The 2000 application is based on the 2000 CTPP Part 3 means of transportation to work table which does contain the field “work at home” whenever the origin (residence) and the destination (workplace) geography are the same. What this means is that in 1990 the workers who “work at home” need to be added to the 1990 flow data, whenever the origin and destination locations are the same, if a correct comparison is to be made with 2000.

A table exists at this location that compares 2000 with 1990 whenever the geography in 2000 matches 1990. This table contains work at home in 2000 and 1990. The reader should add the 1990 values for “workers at home” to the 1990 flow data (from the application) whenever the origin and workplace geography are the same.
