If you received a mailed invitation to participate in the 2018 to 2019 Household Travel Survey, please visit the Travel Behavior Inventory study website to participate and learn more about the study.

The 2018 study will run from October 2018 through October 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 are part of the “travel demand” in the region that helps shape plans for highways, transit facilities, and bike and pedestrian connections.

In 2015, the Council conducted a study that evaluated the way we administer the Travel Behavior Inventory (TBI) household survey, and how we use the data for travel forecasting and funding decisions. Following that study, the Council shifted the survey to a continuous cycle, collecting data every two years to keep pace with rapid changes in the transportation industry.

The new TBI is a 10-year program that includes:

  • A household travel survey that starts in 2018
  • A once-in-five-years survey of on-board transit riders
  • Other travel behavior data collection

These data will help the regional travel-demand forecasting model be more up to date and valid in order to forecast traffic and transit ridership for all major projects.

The TBI is also an important source of data for planners and policymakers to better understand travel, specifically emerging transportation trends in the region.

Data from the previous TBI studies in 2000 and 2010 was instrumental in the planning and approval of every major transportation project built in the region in the past 10 years.
