The CHTS is an in-depth study of the state's household travel and activity patterns. The California Department of Transportation, Caltrans, and its partner agencies, will be asking more than 60,000 households to identify where and how they traveled on a specific, designated travel day (24 hours). In order to ensure a sample that is representative of the state population, each household will be asked a series of detailed questions about their demographic and socioeconomic (such as age, gender, income level) and travel characteristics, and access to transportation. When completed, the data will be used to estimate how much travel is generated by all households.
