Convenient and affordable shared mobility options can attract riders to fixed-route public transit by providing a seamless first-mile/last-mile connection, but can also have unintended impacts. This session will feature city leaders from Seattle, Los Angeles, Boston, Washington D.C., and Santa Monica paired with industry thought leaders to discuss the impacts of shared use on transit systems and mass mobility. The discussion will focus on policy best practices that are being adopted in order to maximize expansion of mobility while maintaining equity, reducing congestion, and ensuring that other impacts are mitigated during this period of rapid expansion of shared mobility options. Finally, this session will feature a compilation of policy and planning initiatives that transit agencies, cities, MPO’s, and other government agencies should adopt during this transformational period in transportation.
