The household and commercial vehicle survey data are used to update the light-duty vehicle choice models. These models are used to generate light duty vehicle demand forecasts and provide understanding about such questions as:

  • How many light duty cars and trucks will be on California roads?
  • How much and what kind of fuels will they use?
  • Does California transportation energy infrastructure meet the future needs in California?

In addition to the main survey of California vehicle owners, the 2017 survey included an add-on survey of Plug-in Electric Vehicle (PEV) owners and the 2019 survey included an add-on survey of Zero Emission Vehicle (ZEV) owners, in both household and commercial light duty vehicle market segments.

The 2019 survey had over 6,000 household and commercial survey respondents, including over 700 PEV owners and 300 FCEV owners.

The information will help planners, energy suppliers, and policy makers anticipate the changing needs of California vehicle owners.
