A Study of the Impact of Ridesharing on Public Transit Ridership
Since ridesharing services were first introduced to the market in 2010, its market share more than tripled. With such a rapid increase in market share, the relationship between the ridesharing industry and public transit started to gain attention from policy makers, transportation planners, and researchers. The current body of research on ridehailing services is limited by its novelty and the corresponding lack of publicly available ridehailing trip data. The conclusions are conflicting. The majority of existing research used stated preference data to identify the relationship between ridesharing and public transit by asking participants' choices. Our proposed research will explore the patterns of ridesharing trips, modeling the relationship between public transit and ridesharing, and propose regulation policies using objective datasets. With an extra-large-scale ridesharing trip data at an individual ridesharing trip level combining with real-time public transit information, the proposed research will be the first to explore the impacts of ridesharing on public transit without using stated preference surveys. We will also explore ways to integrate ridesharing with public transit by linking ridesharing with public transit.
