In recent years there has been significant worldwide activity in shared-use vehicle systems (i.e., carsharing and station cars). Much of this activity is taking place in Europe and North America; however, there has also been significant activity in Asia, primarily in Japan and Singapore. This paper examines the latest shared-use vehicle system activities in both of these countries, beginning with an historical review followed by an evaluation of their current systems. Overall there are several well-established systems in both Japan (approximately 18 systems, 150 vehicles, 3000 members) and...

Can Sharing Economy Platforms Increase Social Equity for Vulnerable Populations in Disaster Response and Relief? A Case Study of the 2017 and 2018 California Wildfires

Ensuring social equity in evacuations and disasters remains a critical challenge for many emergency management and transportation agencies. Recent sharing economy advances – including transportation network companies (TNCs, also known as ridehailing and ridesourcing), carsharing, and homesharing – may supplement public resources and ensure more equitable evacuations. To explore the social equity implications of the sharing economy in disasters, we conducted four focus groups (n=37) of vulnerable populations impacted by California wildfires in 2017 or 2018. To structure these data, we...

Trust and Compassion in Willingness to Share Mobility and Sheltering Resources in Evacuations: A case Study of the 2017 and 2018 California Wildfires

Advances in the sharing economy – such as transportation network companies (e.g., Lyft, Uber) and home sharing (e.g., Airbnb) – have coincided with the increasing need for evacuation resources. While peer-to-peer sharing under normal circumstances often suffers from trust barriers, disaster literature indicates that trust and compassion often increase following disasters, improving recovery efforts. We hypothesize that trust and compassion could trigger willingness to share transportation and sheltering resources during an evacuation.To test this hypothesis, we distributed a survey to...

Chapter 13 - Sharing Strategies: Carsharing, Shared Micromobility (Bikesharing and Scooter Sharing), Transportation Network Companies, Microtransit, and other Innovative Mobility Modes

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. It includes various forms of carsharing, bikesharing, scooter sharing, ridesharing (carpooling and vanpooling), transportation network companies (TNCs), and microtransit. Included in this ecosystem are smartphone “apps” that aggregate and optimize these mobility options, as well as “courier network services” that provide last mile package and food delivery. This chapter describes different...

Policy Considerations for Carsharing and Station Cars: Monitoring Growth, Trends, and Overall Impacts

2004

Since the late-1990s, over 25 U.S. shared-use vehicle programs—including carsharing and station cars—have been launched. Given their presumed social and environmental benefits, the majority of these programs received some governmental support—primarily in the form of startup grants and subsidized parking. As of July 2003, there were a total of 15 shared-use vehicle programs, including 11 carsharing organizations, two carsharing research pilots, and two station car programs. Over the last five years, U.S. carsharing membership has experienced exponential growth.Despite this expansion, the...

Bikesharing across the Globe

Concerns about global climate change, energy security, and unstable fuel prices have caused many decision makers and policy experts worldwideto closely examine the need for more sustainable transportation strategies. Sustainable strategies include clean fuels, vehicle technologies, transportation 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 the globe...

Vehicle Electrification in Carsharing and Transportation Network Company (TNC) Fleets: Current and Future Trends

Shaheen, Susan
Farrar, Emily
2022

This chapter focuses on two shared mobility modes — carsharing and transportation network companies (TNCs, also known as ridesourcing and ride-hailing) — and how they can incorporate electric vehicles (EVs) into their fleets. Shared mobility is the shared use of a vehicle, scooter, bicycle, or other travel mode; it provides users with short-term access to a travel mode on an as-needed basis. Carsharing (e.g., Zipcar, car2go) offers members access to vehicles by joining an organization that provides and maintains a fleet of cars and/or light trucks. Vehicles may be located throughout a city...

Energy Efficiency - Innovations: Driving Prosperity, Slashing Emissions

Cohen, Adam
2020

In recent years, mobility on demand (MOD) is gaining popularity among mobility consumers. This innovative concept is based on the principle that transportation is a commodity where modes have economic values that are distinguishable in terms of cost, journey time, wait time, number of con-nections, convenience, and other attributes. MOD enables consumers to access mobility, goods and services on demand by dispatching or using shared mobility, ...

Planning for Shared Mobility

Cohen, Adam
Shaheen, Susan
2018

In recent years, economic, environmental, and social forces have quickly given rise to the “sharing economy,” a collective of entrepreneurs and consumers leveraging technology to share resources, save money, and generate capital. Homesharing services, such as Airbnb, and peer-to-peer carsharing services, such as Getaround, have become part of a sociodemographic trend that has pushed the sharing economy from the fringe and more to the mainstream. The role of shared mobility in the broader landscape of urban mobility has become a frequent topic of discussion. Major shared transportation...

Framework for Testing Innovative Transportation Solutions: Case Study of Carlink, a Commuter Carsharing Program

Shaheen, Susan A.

2005

Transit accounts for just two percent of total travel in the U.S. One reason for low ridership is limited access; many individuals either live or work too far from a transit station. In developing transit connectivity solutions, researchers often employ a range of study instruments, such asstated-preference surveys, focus groups, and pilot programs. To better understand response to one innovative transit solution, the authors employed a number of research tools, including: a longitudinal survey, field test, and pilot program. The innovation examined was a commutercarsharing model, called...
