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?
  • What will be the transportation energy infrastructure needs of California in the future?

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. The 2019 survey included an add-on survey of Zero Emission Vehicle (ZEV) owners in both household and commercial light duty vehicle market segments. 

Resources Systems Group (RSG) is conducting Energy Commission’s 2024 vehicle survey, currently in progress. RSG will send invitations to a random sample of household and commercial fleet owners to participate in our 2024 survey. Your responses to survey questions are much appreciated, as they help Energy Commission update our understanding of California vehicle owners in 2024 and their energy infrastructure needs. The information will help planners, energy suppliers, and policy makers anticipate the changing needs of California vehicle owners to better meet future infrastructure needs of the state.
