Abstract
This report summarizes the work performed for the 2015–2017 California Vehicle Survey (CVS) project. The 2015–2017 CVS includes revealed preference and stated preference surveys for the residential light-duty vehicle (LDV) sector and the commercial LDV sector in California, as well as an add-on survey for respondents who own or lease plug-in hybrid electric and battery electric vehicles. The results of the survey will be used to update the residential and commercial LDV demand forecasting models. These updated models will be used in generating a LDV fuel demand forecast for the 2017 Integrated Energy Policy Report.
The CVS has been conducted periodically over the past two decades to support updated forecasts as vehicle technologies and preferences change over time. As in previous iterations of the CVS, the 2015–2017 survey comprised two questionnaires: one for the household survey and one for the commercial fleet owner survey. Each survey consisted of two primary components: the revealed preference module, which collected information about current household and establishment vehicle ownership and use behavior, and the stated preference module, which collected information about vehicle preferences and future vehicle ownership and use behavior. In the 2015-2017 survey, the revealed preference module included a set of questions specific to plug-in hybrid electric and battery electric vehicle owners to better understand their purchase decision and charging behavior.
This report describes the design of the survey questionnaires and instruments, the sampling plans, the results of the focus groups and survey pretests, the data collection, and the system of statistical models that were developed using the survey data.
