Abstract:In this study, we use existing modeling tools and data from the San Francisco Bay Area
(California) to understand the potential market demand for a “first” mile transit access service
and possible reductions in vehicle miles traveled (VMT) (and thus GHGs) at both the regional
and station level. We develop a project scenario that targets commuters who drive alone but
could take rail (Bay Area Rapid Transit, or BART) to work. We use travel time, cost, and distance
data from San Francisco Bay Area travel models, Google and BART APIs, and TNC fares to
explore the magnitude of change in overall travel time and cost for travelers who switch from
driving alone to using TNC and BART to travel to work. The analysis indicates that 31% of the
identified drive-alone trips could reduce generalized costs (travel time and monetary costs) by
switching to TNC and BART. If all travelers who could benefit from traveling by TNC and BART,
did in fact switch from drive-alone travel, about 40 thousand new BART trips could be
generated and over a half a million miles of VMT avoided during the morning commute period.
Most of these trips experienced relatively high levels of cost and VMT savings, which may be
more likely to motivate behavioral change. Examination of cost savings by income level and
vehicle availability suggests that the new service is more likely to benefit lower income
households with fewer vehicles. Sensitivity analyses indicate that even with increased TNC fares
and waiting times, there is still a relatively large number of trips that could benefit from
switching from driving to TNC and BART. Tests of a shared TNC BART access service suggest cost
savings and VMT reductions even when travel time costs increase by 60%. Analysis of benefits
by station indicate locations with relatively high market potential (i.e., trips and cost saving) and
environmental benefits (VMT reduction) for early pilot implementation. These results can be
used to estimate potential TNC fare subsidies to increase performance by station to achieve project objectives, such as equitable access, increased BART ridership, and reduced VMT.
