Across all modes, the average Bay Area commute takes longer than ever before, with the average commute now lasting 30 minutes door-to-door. Increasing congestion and longer commutes to job centers in San Francisco and Silicon Valley have contributed to this trend. Importantly, modal choice affects commute duration. Commuters choosing to drive alone spend only 27 minutes getting to work, while those choosing public transit log an average commute time of 49 minutes.
The longer transit commute times are not surprising, given that nearly two-thirds of transit commuters work in San Francisco. Given the impacts on Muni related to congestion within San Francisco, and the long-distance commutes on BART, Caltrain and express buses from other counties, it is difficult for these commuters to get to work in 30 minutes or less. This results in above-average travel times for public transit users.
