In rural areas, cost-effective transit service is challenging due to greater travel distances, lower population densities, and longer travel times than in cities. As a result, the people who rely on public transit contend with infrequent and slow service, and keeping a sufficient number of personal vehicles in reliable working order can be prohibitively expensive for low-income families. UC Davis partnered with the eight San Joaquin Valley Metropolitan Planning Organizations to identify and support development of three innovative mobility pilot concepts for the region. The first pilot is an electric vehicle (EV) carsharing service known as Míocar, located in affordable housing complexes in eight rural communities in Tulare and Kern counties. The second is a volunteer ridesharing service, known as VOGO, which supplements existing transit services in transport-disadvantaged rural areas in San Joaquin and Stanislaus counties. The third is a Mobility-as-a-Service (MaaS) platform that allows planning and payment for fixed and demand-responsive transit services, including VOGO, in San Joaquin and Stanislaus counties. These pilots seek to (a) provide improved access to destinations for individuals with limited transportation alternatives, (b) and achieve greenhouse gas reductions through mode shifts from traditional internal combustion vehicles to EVs, ridesharing, and fixed transit. This report presents the methods and results for “before” and “after” evaluations conducted by UC Davis researchers to assess the performance and impacts of each pilot. The evaluations incorporate service usage data including telematics and MaaS application data, and survey data collected from pilot participants, to assess the programs beginning with pilot launch (2019 and2020) until November 2021. The results provide insights into participant characteristics and barriers to transportation, travel behavior, trip planning activities, and the extent to which the pilots addressed the travel needs of their target populations region.
