Travel Behavior Inventory (TBI)

Where, when and how we travel

If you have received a mailed invitation to participate in the 2018-2019 Household Travel Survey, please visit for more information. A pre-test will be conducted in May 2018 with a full survey launched in October 2018 and running through September 2019.

Did you know that your travel patterns help shape the transportation system of the Twin Cities metro area?

Our daily commutes to and from work. Our errands around town. Vacations and visits to relatives.  Even bike rides and walks. All of these trips figure into the “travel demand” in the region, which affects the plan for highways, transit facilities, and bike and pedestrian connections.

In 2015, the Council conducted a study of the decennial Travel Behavior Inventory (TBI) looking at the region’s existing and future travel model needs, evolving survey methods, and funding options. Following that study, the Council proposed to transition the TBI to a continuous program, centered around a biennial household travel survey. The new TBI is a ten-year program consisting of a biennial household travel survey, a once-in-five years transit on-board survey, and other direct and third-party travel behavior data collection to support the currency and validity of the regional travel demand forecast model. The TBI also serves as an important source of data for planners and policymakers to understand travel, and particularly emerging trends in travel in the region.

The surveys are used to provide policymakers and researchers the most current data about travel in the region.  They are also being used to develop a major update to the region’s travel demand forecasting models, which are used to forecast traffic and transit ridership for all major projects.
Data from the 2000 and 2010 TBIs was instrumental in planning and justifying every major transportation project built in the region in the past decade.
