Bridging the Income and Digital Divide with Shared Automated Electric Vehicles

Jessica Lazarus, Gordon Bauer, Jeffery Greenblatt, Susan Shaheen
2021

This research investigates strategies to improve the mobility of low-income travelers by incentivizing the use of electric SAVs (SAEVs) and public transit. We employ two agent-based simulation engines, an activity-based travel demand model of the San Francisco Bay Area, and vehicle movement data from the San Francisco Bay Area and the Los Angeles Basin to model emergent travel behavior of commute trips in response to subsidies for TNCs and public transit. Sensitivity analysis was conducted to assess the impacts of different subsidy scenarios on mode choices, TNC pooling and match...

Shared ride services in North America: definitions, impacts, and the future of pooling

Susan Shaheen, Adam Cohen
2018

Shared ride services allow riders to share a ride to a common destination. They include ridesharing (carpooling and vanpooling); ridesplitting (a pooled version of ridesourcing/transportation network companies); taxi sharing; and microtransit. In recent years, growth of Internet-enabled wireless technologies, global satellite systems, and cloud computing - coupled with data sharing – are causing people to increase their use of mobile applications to share a ride. Some shared ride services, such as carpooling and vanpooling, can provide transportation, infrastructure, environmental, and...

Synthesis of State-Level Planning and Strategic Actions on Automated Vehicles: Lessons and Policy Guidance for California

Stephen Wong, Susan Shaheen
2020

This synthesis provides a summary and comparative analysis of actions states across the United States are taking inresponse to automated vehicles (AVs). The research focuses on state-level stakeholder forums (e.g., task forces, committees) and state-level strategic actions (e.g., studies, initiatives, programs) initiated by a state legislature, agovernor, or a state agency. The analysis found that AV stakeholder forums and strategic actions address a diverse set offocus areas, but they pay minimal attention to the implications of AVs on the environment, public health, social equity,...

Mobility on Demand Planning and Implementation: Current Practices, Innovations, and Emerging Mobility Futures

Susan Shaheen, Adam Cohen, Jacquelyn Broader, Richard Davis, Les Brown, Radha Neelekantan, Deepak Gopalakrishna
2020

This report provides Mobility on Demand (MOD) planning and implementation practices and tools to support communities. The report discusses different stakeholders in the MOD ecosystem and the role of partnerships in filling spatial, temporal, and other service gaps. Additionally, the report discusses how MOD can be integrated into transportation planning and modeling. The report also discusses shared mobility implementation considerations, such as rights-of-way management, multimodal integration, data sharing, equity, labor impacts, and the role of pilot evaluations. Finally, the...

2019

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 dataconnectivity, sharing, and vehicle automation. Shared, on-demand mobility represents asustainable vision for future mobility with a reliable network of multimodal options that areavailable to all travelers. On March 22, 2019, the Local Government Commission ...

Who Will Own the Cars That Drive Themselves?

May 29, 2020

uber vehicles

It was a difficult question even before the coronavirus pandemic hit: When self-driving cars eventually rule the roads, will Americans own their cars or make use of ride-hailing fleets?

The challenge is now threefold. Self-driving car technology had already reached a plateau, and getting to full Level 5 autonomy will be more difficult than many had thought. With the nation’s economy hobbled by the virus,...

Mobility on Demand in the United States

Susan Shaheen, PhD and Adam Cohen
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...

Shared Mobility Policy Playbook

Susan Shaheen, PhD, Adam Cohen, Michael Randolph, Emily Farrar, Richard Davis, and Aqshems Nichols
2019

The Shared Mobility Policy Playbook provides an introduction and definitions of shared mobility services, mode-specific resources for agencies looking to develop policies in their community, and policy-focused tools demonstrating case studies and best practices for shared mobility.

This playbook has been designed for individuals and practitioners who want to know more about shared mobility and to communities interested in incorporating shared mobility into their transportation ecosystem. It is a practical guide with resources, information, and tools for local governments,...

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

Susan Shaheen, PhD and Mohamed Amine Bouzaghrane
2019

Purpose of Review: The purpose of this review is to present findings from recent research on Shared automated vehicles (SAV) impacts on mobility and energy.

Recent Findings: 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...
