To estimate the number of cars on the road and the number of passengers riding public transit, below are charts that show how many vehicles used Bay Area bridges and how many trips were taken in the BART system each month, starting in January 2019.

These figures are intended to serve as a proxy to show the increase (or decrease) in traffic and ridership volumes. In all toll bridge figures, the data show vehicle crossings in the toll direction only. BART ridership is represented by the average of weekday exits from all stations.
