In the Peninsula context, a shuttle is a short transit service oriented toward first/last mile or an individual community’s needs. While “shuttle” implies a small vehicle, a range of vehicle types are in operation, including some full-size 45-foot buses. Shuttles can serve commute or non-commute trips, and may be operated by cities, transit agencies, or the private sector, either directly or via a contractor. Shuttles are funded directly by local jurisdictions or the private sector, often with support from grants by SMCTA, C/CAG, MTC, and the Bay Area Air Quality Management District.
Shuttles have traditionally been grouped into two categories: commuter shuttles and community shuttles. Commuter shuttles provide first/last mile connections to/from regional transit primarily to access employment centers during peak periods.
Community shuttles provide all-day, midday, or weekend service generally within a single community for basic needs like shopping, dining, and medical appointments, often serving transit-reliant populations. However, the distinctions between commuter and community shuttles have been increasingly blurred as more shuttles serve both markets.
The Peninsula shuttle program serves most cities in San Mateo County as well as some in Santa Clara County (Figure 1), which have been suspended due to the COVID-19 Pandemic as of 2020. Of 45 routes in 2019, 37 operated in San Mateo County and eight routes operated in Santa Clara County (affiliated with the program through funding or grant sponsorship via Caltrain). In 2019, shuttles were operating in 18 cities with service to 17 regional transit stations, and was managed by at least 14 different public and private sector entities.
Many shuttles operate on the Peninsula beyond this shuttle program. These include those operated by large employers, city-run shuttles not funded by the program, and even some shuttle-like fixed-route and on-demand bus services provided by SamTrans and VTA. Because these services are not part of the Peninsula shuttle program funded by SamTrans, Caltrain, the SMCTA, or their partners, they are outside the scope of this study.
