The Bay Area’s prosperity is threatened by fragmentation in the public transit system: Riders and decision-makers contend with more than two dozen transit operators. Inconsistent transit experiences and disjointed planning and investment make our transit system less efficient, less usable, and less likely to help us meet our goals for a thriving and sustainable region.
The Bay Area economy and labor market is increasingly regional: 29 percent of Bay Area commuters cross a county boundary to get to work each day. These long commutes, many of which traverse the bay, put incredible stress on constrained transportation corridors. Two-thirds of Bay Area commuters drive to work alone, creating significant congestion on the region’s freeways and bridges. Dramatic growth in employer-run shuttles over the last few years demonstrates the demand for alternatives, both to car travel and to regional transit such as BART and Caltrain, which are running short on room for passengers. As people move further out to find affordable places to live, the expectation is that regional travel will grow.
For these reasons and others, such as managing sprawl and reducing greenhouse gas emissions, the Bay Area invests heavily in transit. It is spending $21 billion over the next 25 years to build public transit infrastructure and $159 billion to operate and maintain the transit system. Despite similar expenditures in the past, overall transit ridership has not been growing in the Bay Area. Most trips within the Bay Area are still made by car, with transit accounting for only 3 percent of all trips. Part of the reason it’s hard to increase transit ridership here may be due to how fragmented our system is compared to others.
Many could benefit from more integrated transit
We have the opportunity to increase the market share for transit in places where there is significant demand for regional travel. Half as many people travel from central Alameda County to San Francisco as travel from the Peninsula/Silicon Valley/San Jose to San Francisco, for example. However, 44 percent of the Alameda County trips use public transit while just 17 percent of the Silicon Valley trips use public transit.
