From page 7... ... 7 Transportation and Lifestyle Choices Associated with Shared Mode and Transit Use Among survey respondents, greater use of shared modes is associated with greater likelihood to use transit frequently, own fewer cars, and have reduced transportation spending. Supersharers (people who routinely use several shared modes, such as bikesharing, carsharing, and ridesourcing) Read the entire page →
From page 8... ... 8 Shared Mobility and the Transformation of Public Transit the entire range of mobility options rather than a single top mode, supersharers said they used transit and all of the other shared-use modes with frequency equal to or greater than the general respondents (Figure 2) , and reported driving alone or with friends about 10% less than the overall group.

From page 9... ... Findings 9 The picture of how people mix and match various mobility options can be further developed by looking at all of the modes respondents reported having used in the last 3 months (Figure 4) Read the entire page →

From page 11... ... Findings 11 in these responses; however, if these ownership differences are indeed attributable to the earlyadopting supersharers' selecting from a larger menu of mobility options, these findings suggest a promising path to vehicle ownership reductions and associated benefits from reduced solo car travel if these lifestyle choices become more broadly dispersed. Increasing the breadth of shared mobility options and broadening access for more neighborhoods and communities could help cities meet goals to reduce single occupancy driving. Read the entire page →
From page 12... ... 12 Shared Mobility and the Transformation of Public Transit driving to work less often versus 4% who reported driving more; 37% of supersharers drove a car to work less often, versus 4% who said they drove more. For errands and recreation, 32% of the wider group and 37% of supersharers, respectively, drove less for errands and recreation, versus 10% and 11% who drove more; 43% and 42% said they used public transit more, versus 28% and 32% who said they used transit less.

From page 13... ... Findings 13 The interviews, survey, and data analysis conducted for this study together suggest that public transit and shared modes complement one another by serving different trip types and making car-free or car-light lifestyles feasible for more people. Different shared modes seem to fill specific niches in the mobility ecosystem, with ridesourcing used most frequently for social trips, late at night, and when alcohol is a factor; carsharing used for errands and off-peak trips to areas without good transit access; and bikesharing used for last-mile connections and acting as a pressure valve for crowded transit systems during peak hours.

From page 17... ... Findings 17 situationally -- and generally not daily -- as a mode that fills in gaps or works under specific circumstances rather than as the core mode of their commute. This pattern is similarly reflected in the frequency of use: even among respondents who reported ridesourcing as their top shared mode, only 7% said they use ridesourcing daily, whereas 42% reported using it 1–3 times per month.

From page 19... ... Findings 19 Trip length and speed may be a key concern in decisions about which mode to use, with faster modes increasingly preferable as trips get longer. Although the survey did not ask specifically about the distance of particular trip types, it did ask about typical trip lengths by mode. Read the entire page →
From page 20... ... 20 Shared Mobility and the Transformation of Public Transit A comparison of the travel times for the same trip using transit or ridesourcing underscores the rational basis for the usage patterns suggested by the survey and demand analysis. For many trips, transit is a much faster choice at rush hour, especially along fixed-guideway corridors. Read the entire page →

Findings 31 • Route combination for riders with similar origins/destinations; • Mobile app-based payment integrated into reservation systems; • Ability to track vehicle arrival and share trip details, location, and estimated arrival time with caregivers or other third parties; and • Real-time customer feedback. The second, and perhaps more revolutionary, application would be the direct provision of transportation services to persons with disabilities by ridesourcing or microtransit operators.

From page 32... ... 32 Shared Mobility and the Transformation of Public Transit • Heightened vehicle safety and inspection requirements and insurance costs associated with ADA provision and the transportation of fragile individuals.

From page 33... ... Findings 33 access these services but either don't have a smartphone or can't use the default interface. Because it ultimately delivers the request to a ridesourcing provider, this arrangement is at present outside the realm of paratransit; however, paratransit providers that move to dynamic reservation systems could use this option.

From page 37... ... Findings 37 Service Links and Hand-offs Several transit agencies have begun working directly with ridesourcing companies and other private providers to link their services or to promote hand-offs through targeted marketing agreements. These arrangements -- which include first- and last-mile partnerships, linked mobile apps, and guaranteed ride home programs -- can help facilitate the creation of a robust, interconnected network of mobility options that supports car-free and car-light living.
