Ridehailing, uncertainty and sustainable transportation

This study investigates how stakeholders throughout the state of California view the potential impacts of ridehailing services such as Uber or Lyft, to transportation systems, and how to address such impacts. Ridehailing is one of several emerging shared use mobility alternatives, poised to impact transportation systems, for better or worse.

For worse if these new services serve merely as a less expensive taxi, allowing more people to forego alternative modes of transportation like public transit and biking, thereby leading to increases in VMT and emissions and worsening congestion impacts. The high degree of uncertainty surrounding the impacts of these services presents challenges to stakeholders involved in transportation planning and policymaking. How transportatio...
