Shared Mobility

Similarities and Differences of Mobility on Demand (MOD) and Mobility as a Service (MaaS)

Susan Shaheen and Adam Cohen

In cities around the world, innovative and emerging shared modes are offering residents, businesses, travelers, and other users more options to access mobility, goods, and services. As these shared modes build a network of services in many cities, consumers are increasingly engaging in more complex multimodal decision-making processes. Rather than making decisions between modes, travelers are “modal chaining” to optimize route, travel time, and cost. Additionally, digital information and fare integration are contributing to new on-demand access models for mobility and goods delivery....

Mobility and Development: Innovations, Policies and Practices

Susan Shaheen, PhD, Adam Cohen

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...

An Evaluation of Via Rideshare Service in West Sacramento: An Exploratory Analysis Through Surveys and Expert Interviews

Elliot Martin, Aqshems Nichols, Susan Shaheen
The UC Berkeley Transportation Sustainability Research Center (TSRC) conducted an evaluation for the City of West Sacramento of the pilot Via Rideshare System, which began providing rides to customers in May of 2018 and is currently in operation. This analysis presents the findings from surveys and expert interviews. Surveys were deployed to both users and non-users of the pilot service in order to assess the behavioral impacts of the system on users and to...

Susan Shaheen, UC Berkeley Transportation Sustainability Research Center Co-Director discusses shared automated vehicles with Polictico.

“If you could get more people sharing a car, when you start to look at the vehicle miles traveled and the greenhouse gas and criteria pollutant impacts, they’re likely going to be lower,” said Susan Shaheen, a California Air Resources Board member and...

Going My Way? Understanding Curb Management and Incentive Policies to Increase Pooling Service Use and Public Transit Linkages in the San Francisco Bay Area

Wesley Darling, Jacquelyn Broader, Adam Cohen, Susan Shaheen

Despite lower user costs, only 20% to 40% of transportation network company (TNC) us-ers select a pooled, or shared, ride option. Why are existing TNC users not selecting the pooled option or using TNCs to connect to public transit, and what role do built environment features and incentives play in their decision? This study explores the factors that influence TNC user decisions through a multi-method approach comprising photovoice small group discussions and a workshop. Between...

An Assessment of the Potential Weather Barriers of Urban Air Mobility (UAM)

Colleen Reiche, PhD, Frank Brody, Christian McGillen, Joel Siegel, Adam Cohen

Urban Air Mobility (UAM), a subset of advanced air mobility, is a concept that envisions safe, sustainable, affordable, and accessible air transportation for passenger mobility, cargo delivery, and emergency management within or traversing a metropolitan area. In recent years, several companies have designed and tested enabling elements of this concept, including; prototypes of vertical take-off and landing (VTOL) aircraft, operational concepts, and market studies to understand potential business models. While UAM may be enabled by the convergence of several factors, a number of barriers...

Bikesharing across the Globe

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

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...
