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...

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...

Shared Micromobility: Policy, Practices, and Emerging Futures

Shaheen, Susan A.

2022

Shared micromobility – or short-term access to shared bikes and scooters – provides a flexible alternative for households living in urban areas, households seeking first and last-mile connections to public transportation, and those without access to a private vehicle trying to access jobs and essential services. Up until the global pandemic, shared micromobility grew worldwide on a relatively steep growth curve, beginning in the early 2010s. Shared micro-mobility is a transportation strategy that enables users’ short-term access to a transportation mode on an as-needed basis (Shaheen et al...

ITS Standards: A System Management Perspective

Intihar, Chris
Hall, Randolf
1997

This working paper is part of a larger project examining how the State of California should respond to the National System Architecture (NSA) for Intelligent Transportation Systems. The specific focus of this paper is on the role of standardization in managing and controlling the transportation system. The paper reviews activities and processes used by standards setting organization in transportation. We conclude that national and international standards will continue to address the needs for defining common interfaces...
