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...

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.

Transportation Network Companies (TNCs) like Lyft, Uber, and their global counterparts have expanded around the world over the past decade and have changed the way that people travel around cities and regions. The individual mobility benefits provided by TNCs have been clear. Passengers can summon a vehicle quickly via smartphone from almost anywhere to take them almost anywhere, with advance communication on estimated wait time, travel time, and cost. TNCs may also provide users with added mobility benefits, especially for those living in areas where public transit service is infrequent...

Shared-Use Vehicle Systems

Shaheen, Susan
2002

In recent years, shared-use vehicle systems have garnered a great deal of interest and activity internationally as an innovative mobility solution. In general, shared-use vehicle systems consist of a fleet of vehicles that are used by several different individuals throughout the day. Shared-use vehicles off the convenience of the private automobile and more flexibility than public transportation alone. These systems are attractive since they offer the potential to lower a user’s transportation costs; reduce the need for parking spaces in a community; improve overall air quality; and...

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...

One-Way Carsharing's Evolution and Operator Perspectives from the Americas

2015

Classic roundtrip carsharing has been documented as a strategy to reduce car ownership and vehicle miles/kilometers traveled in urban areas. The expansion of carsharing and other forms of shared-use mobility have led to a growing interest in understanding the latest models. In recent years, one-way carsharing has gained momentum across the globe with 18 operators providing services in ten countries worldwide. One-way carsharing does not require its users to return the vehicle to the same location from which it was accessed (in contrast to roundtrip carsharing). Users typically pay by the...

Mobility and the Sharing Economy: Potential to Overcome First- and Last-Mile Public Transit Connections

Shaheen, Susan, PhD
Chan, Nelson
2016

Shared mobility—the shared use of a motor vehicle, bicycle, or other mode—enables travelers to gain short-term access to transportation modes on an as-needed basis. The term “shared mobility” includes the modes of carsharing, personal vehicle sharing (peer-to-peer carsharing and fractional ownership), bikesharing, scooter sharing, traditional ridesharing, transportation network companies (or ridesourcing), and e-Hail (taxis). It can also include flexible transit services, including microtransit, which supplement fixed-route bus and rail services. Shared mobility has proliferated in global...

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 benefits including: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...
