January 27, 2021: The SACOG travel-modeling team has a powerful
new source of data that enables even more fine-tuned analysis of
travel trends in the Sacramento region.
In a Big Data pilot project partnership with Caltrans and the
California Air Resources Board, the team has access to the
software-as-a-service platform Replica for 2021. Replica uses
machine learning to turn many streams of inputs — raw data from
GPS to cell phone apps to credit card purchases, and many more —
into valuable insights useful for transportation modelers,
planners, and policy-makers.
These insights are displayed in two different forms on the
Replica platform: Nationwide Trends and Local Places. The
Nationwide Trends is a weekly snapshot of activities across the
United States such as numbers of daily trips, vehicle miles
traveled, trip start times, trips to work and school, as well as
spending across sectors such as gas stations, grocery stores, and
restaurants and bars. Users can view the trends at the state,
county, and census tract levels.
