What’s Behind Recent Transit Ridership Trends in the Bay Area? Volume II: Trends among Major Transit Operators

Transit ridership in the San Francisco Bay Area is falling. Yet some operators, areas, times, directions, routes, modes, and services have fared better than others. These differences help reveal the causes of the Bay Area’s overall ridership slump and inform policy and service decisions that aim to restore Bay Area transit use. To investigate these temporal and spatial trends, we analyze ridership on the eight largest Bay Area transit operators in considerable detail in Volume II of our report.Overall, we find a significant level of “peaking.” Ridership losses at off-peak hours, on weekends, on outlying routes, in non-commute directions, and on smaller operators account for a large and disproportionate share of the whole region’s patronage decline. Downtown San Francisco and commute-oriented rail lines like Caltrain have gained ridership as less central, lower-service routes have lost patronage. These patterns match our statistical modeling of BART ridership, on which station-area jobs had the greatest influence, one that has grown over time. The most significant exceptions to the Bay Area’s peaking problem are operators in urban cores, like Muni and AC Transit, where residential and employment density throughout the network have blunted peaking, though not necessarily overall losses.Absolute patronage declines and peaking are intertwined but distinct problems, with cross-cutting divisions. Yet on all agencies, we see at least some evidence of peaking. The resulting dependence on peak trips both incurs high costs and depresses passenger satisfaction
