The market for personal mobility is changing rapidly due to shifting social and cultural trends, as well as technological advances, such as smartphones, information processing, widespread data connectivity, sharing, and vehicle automation. Shared, on-demand mobility represents a sustainable vision for future mobility with a reliable network of multimodal options that are available to all travelers. On March 22, 2019, the Local Government Commission (LGC) and the Transportation Sustainability Research Center (TSRC) at the University of California, Berkeley hosted the Caltrans Shared...

Mobility and the Sharing Economy: Industry Developments and Early Understanding of Impacts

Shared mobility—the shared use of a vehicle, bicycle, or other mode—is an innovative transportation strategy that enables users to gain short-term access to transportation modes on an “as-needed” basis. Shared mobility includes various forms of carsharing, bikesharing, ridesharing, on-demand ride services, and microtransit. Additionally, smartphone and mobile “apps” aggregate and optimize these mobility services and are critical to many shared mobility modes. Courier network services connect couriers using their personal vehicles or bicycles with freight and seek to disrupt the existing...

Shared Automated Vehicle (SAV) Pilots and Automated Vehicle Policy in the U.S.: Current and Future Developments

Stocker, Adam
Shaheen, Susan
2018

Many automated vehicle (AV) developers and technology companies are fast pursuing the public deployment of these vehicles as part of a shared fleet. To the best of our knowledge, this chapter is the first comprehensive compilation of 17 active shared automated vehicle (SAV) pilot projects in the U.S., as of February 2018. This chapter also reviews AV regulatory efforts at the federal, state, and local levels. By tracking trends and classifying the differences between SAV pilots, we foster a better understanding of how this technology might roll out in the coming decades. While 30 states...

Mobility and Energy Impacts of Shared Automated Vehicles: A Review of Recent Literature

2019

The purpose of this review is to present findings from recent research on Shared automated vehicles (SAV) impacts on mobility and energy. While the literature on potential SAV impacts on travel behavior and the environment is still developing, researchers have suggested that SAVs could reduce transportation costs and incur minimal increases in total trip time due to efficient routing to support pooling. Researchers also speculate that SAVs would result in a 55% reduction in energy use and ~ 90% reduction in greenhouse gas (GHG) emissions.SAV impacts on mobility and energy are uncertain....

Shared Automated Mobility: Early Exploration and Potential Impacts

Stocker, Adam
Shaheen, Susan
2017

Automated vehicles, if shared, have the potential to blur the lines between public and private transportation services. This chapter reviews possible future shared automated vehicle (SAV) business models and their potential impacts on travel behavior. By examining the impacts of non-automated shared mobility services like carsharing and ridesourcing, we foster a better understanding of how current shared mobility services affect user behavior. This serves as a starting point to explore the potential impact of SAV services. Several key studies covering the topic are discussed. Although the...

Mobility on Demand in the United States

Shaheen, Susan A.
Cohen, Adam
2020

The growth of shared mobility services and enabling technologies, such as smartphone apps, is contributing to the commodification and aggregation of transportation services. This chapter reviews terms and definitions related to Mobility on Demand (MOD) and Mobility as a Service (MaaS), the mobility marketplace, stakeholders, and enablers. This chapter also reviews the U.S. Department of Transportation’s MOD Sandbox Program, including common opportunities and challenges, partnerships, and case studies for employing on-demand mobility pilots and programs. The chapter concludes with a...
