The Travel Behavior Inventory (TBI) Household Survey is a travel survey of households in the greater Twin Cities region that has been conducted every 10 years since 1949. This survey supports transportation planning and forecast model development. In 2018, two significant changes occurred to the TBI household survey program: (1) the survey moved from a decennial survey to recur every other year and (2) the survey began using spartphone GPS applications as the primary means of data collection. The 2018-2019 TBI Household Survey was fielded from October 1, 2018 through September 30, 2019. Smartphone participants completed a 7-day travel diary. Online and call center participants completed a 1-day travel diary. The same questionnaire was used for smartphone, online, and call center participants. The survey was available in English, Spanish, Karen, Oromo, Somali, and Hmong.
