Shared Micromobility: Policy, Practices, and Emerging Futures

2022

Shared micromobility services provide travelers with short-term access to shared devices, such as bikes and scooters. Common shared micromobility services include bikesharing and scooter sharing, services that allow these devices to be used for on-demand one-way or roundtrip travel. Advances in internet technology (IT)-based systems led to the growth of shared micromobility since its advent with bikesharing in Europe in the 1960s. However, shared micromobility ridership began to decrease during 2019, in part due to challenges like improper device parking. Generally, shared micromobility...

Transportation Network Companies Might Be Pulling Riders from Public Transit, but This Could Change

Transportation Network Companies (TNCs, also known as ridehailing and ridesourcing) have expanded across California over the past decade and changed the way people travel. Using a smartphone, travelers can quickly summon a vehicle from almost anywhere and know what the estimated wait time, travel time, and cost will be before stepping into the vehicle. While TNCs are clearly addressing an unmet need for travelers, their growing popularity has raised a number of policy questions, including if TNCs are shifting people away from public transit and other travel modes (e.g., carshare,...

Mobility and Development: Innovations, Policies and Practices

Susan Shaheen, PhD, Adam Cohen
2021

Innovative and emerging transportation services, such as shared mobility, MOD, and MaaS, are expanding across the developing world. MOD emphasizes the commodification of passenger mobility and goods delivery and transportation systems management, whereas MaaS primarily focuses on passenger mobility aggregation and subscription services. The public sector can support and leverage MOD and MaaS through a variety of service, information, fare integration, and data sharing partnerships. In particular, the growth of “super” apps in Africa and Asia are offering consumers all-in-one mobile...

Bikesharing across the Globe

Susan Shaheen Ph.D. , Stacey Guzman, Hua Zhang
2012

Concerns about global climate change, energy security, and unstable fuel prices have caused many decision makers and policy experts worldwide to closely examine the need for more sustainable transportation strate- gies. Sustainable strategies include clean fuels, vehicle technologies, trans- portation demand management, and integrated land use and transportation strategies (Shaheen and Lipman 2007). Bikesharing—the shared use of a bicycle fleet—is one mobility strategy that could help address many of these concerns. In recent years, interest in this evolving concept has spread across...

Red bike with brand label "JUMP"

When JUMP’s bright red bikes started appearing on the streets of San Francisco last year, Ian Chesal was relieved. His lengthy commute, from the hills of Oakland to his tech company’s San Francisco office, involved driving to the subway, sitting for 40 minutes, and then walking a mile to his office. Once the JUMP bikes appeared, he could use his phone to unlock one outside his subway stop, and ride it...
