Urban Air Mobility (UAM) is an emerging concept envisioning a safe, efficient, accessible, quiet, and multi-use air transportation for passenger mobility, cargo delivery, and emergency management within or traversing a metropolitan area. Urban air mobility is part of the U.S. Department of Transportation’s broader vision for Mobility on Demand (MOD), an innovative transportation concept evolving around connected travelers, where consumers can access mobility and goods delivery services on demand by dispatching or using urban aviation services, courier services, shared automated vehicles,...

Shared Mobility in Low- and High-Income Regions

2022

Although shared and informal transport are not new concepts in low- and middle- income countries (LMICs), a variety of economic, environmental, and social forces are contributing to the growth of shared mobility in LMICs around the world. Shared mobility—the shared use of a vehicle, motorcycle, autorickshaw, minibus, scooter, bicycle, or other travel mode—is an innovative transportation strategy that enables users to have short-term access to a transportation mode. This paper documents key shared mobility and informal transport concepts, terms, and definitions around the world. The paper...

Evaluating the Public Perception of a Feebate Policy in California through the Estimation and Cross-Validation of an Ordinal Regression Model

Martin, Elliot, PhD
Shaheen, Susan, PhD
Lipman, Timothy
Camel, Madonna
2014

Understanding the roots of policy perception can be critical for informing the design and implementation of innovative public policies.  Feebates is one such innovative policy and in the context of new vehicles can be designed to offer buyers a rebate for the purchase of low-emission vehicles and a fee for the purchase of high-emission vehicles.  Because feebates is a policy that directly impacts the consumer, understanding the dynamics of public perception, support, and opposition is important.  This study explores the public perception of a feebate policy...

Social Equity Impacts of Congestion Management Strategies

Shaheen, Susan, PhD
Stocker, Adam
Meza, Ruth
2019

This white paper examines the social equity impacts of various congestion management strategies. The paper includes a comprehensive list of 30 congestion management strategies and a discussion of equity implications related to each strategy. The authors analyze existing literature and incorporate findings from 12 expert interviews from academic, non-governmental organization (NGO), public, and private sector respondents to strengthen results and fill gaps in understanding. The literature review applies the Spatial – Temporal – Economic – Physiological – Social (STEPS) Equity Framework (...

Public Transit and Shared Mobility COVID-19 Recovery: Policy Options and Research Needs

Shaheen, Susan, PhD
Wong, Stephen, PhD
2020

While the COVID-19 crisis has devastated many public transit and shared mobility services, it has also exposed underlying issues in how these services are provided to society. As ridership drops and revenues decline, many public and private providers may respond by cutting service or reducing vehicle maintenance to save costs. As a result, those who depend on public transit and shared mobility services, particularly those without access to private automobiles, will experience further loss of their mobility. These transportation shifts will be further influenced by changing work-from-home...

Innovative Mobility: Carsharing Outlook Carsharing Market Overview, Analysis, And Trends.

Shaheen, Susan, PhD
Cohen, Adam
2020

Since 1998, 94 carsharing programs have been deployed in North America - 40 are operational and 52 are defunct. As of January 1, 2018, there were 18 active programs in Canada, 21 in the United States (U.S.), and one program in Mexico. In North America, carsharing membership totaled approximately 2,110,111 members sharing 23,376 vehicles. The three largest carsharing operators in the U.S. and Canada accounted for 91% and 86% of the total membership, respectively. Only one operator provided service in Mexico as of January 2018.

California Transportation Plan 2050: Northern and Southern California Visioning Sessions Findings

Shaheen, Susan, PhD
Totte, Hannah
Cohen, Adam
2018

Improving California’s transportation system requires cross-sector collaboration, particularly as technologies, policies, and regulations develop simultaneously. The California Transportation Plan (CTP) 2050 aims to integrate perspectives from a diverse array of stakeholder that may not typically participate in the statewide planning process. The Visioning Sessions were conducted in two day-long visioning workshops in October 2018 in Southern and Northern California. Overall, these visioning sessions initiated a much-needed dialogue among experts and practitioners from diverse backgrounds...

Compliance, Congestion, and Social Equity: Tackling Critical Evacuation Challenges through the Sharing Economy, Joint Choice Modeling, and Regret Minimization

Wong, Stephen D.
2020

Evacuations are a primary transportation strategy to protect populations from natural and humanmade disasters. Recent evacuations, particularly from hurricanes and wildfires, have exposed three critical evacuation challenges: 1) persistent evacuation non-compliance to mandatory evacuation orders; 2) poor transportation response, leading to heavy congestion, slow evacuation clearance times, and high evacuee risk; and 3) minimal attention in ensuring all populations, especially those most vulnerable, have transportation and shelter. With ongoing climate change and increasing land development...

The Potential Societal Barriers of Urban Air Mobility (UAM)

Shaheen, Susan, PhD
Cohen, Adam
Farrar, Emily
2018

Urban Air Mobility (UAM) is an emerging concept of air transportation where small package delivery drones to passenger-carrying air taxis operate over populated areas, from small towns to the largest cities are being considered. This could revolutionize the way people move within and around cities by shortening commute times, bypassing ground congestion, and enabling point-to-point flights across cities. In recent years, several companies have designed and tested enabling elements of this concept, including; prototypes of Vertical Take-Off Landing (VTOL) capable vehicles, operational...

The Benefits of Carpooling

Shaheen, Susan, PhD
Cohen, Adam, MCRP
Bayen, Alexander, PhD
2018

Carpooling allows travelers to share a ride to a common destination and can include several forms of sharing a ride, such as casual carpooling and real-time carpooling. Because carpooling reduces the number of automobiles needed by travelers, it is often associated with numerous societal benefitsincluding:1) reductions in energy consumption and emissions, 2) congestion mitigation, and 3) reduced parking infrastructure demand. In recent years, economic, environmental, and social forces coupled with technological innovations are encouraging shared and pooled services. Shared mobility is...
