2016 National Household Travel Survey

The National Household Travel Survey

Caltrans and the Federal Highway Administration have initiated a yearlong process of inviting thousands of California households to participate in the National Household Travel Survey (NHTS). If you have received a packet in the mail inviting your household to participate, the survey process is very simple.

(To view this video in Spanish, click here.)

Just follow these three easy steps:

  1. Fill out the brief questionnaire that comes with your invitation and mail it back in the prepaid return envelope.
  2. You will receive a packet with a travel log and an assigned travel day. On your assigned day, everyone in your household will use the log to keep track of every trip they take - driving, walking, taking the bus, etc.
  3. After you have completed the log, you will enter your travel log online or by phone and answer a few additional questions, a process that usually takes 20 to 25 minutes.

For more information on the National Household Travel Survey, visit the NHTS webpage at or call 1.855.350.NHTS (6487).
