Bikesharing in Europe, the Americas, and Asia: Past, Present and Future

Authors: Susan Shaheen, Stacey Guzman, Hua Zhang Published: January 1, 2010 Abstract:  Growing concerns over global motorization and climate change have led to increasing interest in sustainable transportation alternatives, such as bikesharing (the shared use of a bicycle fleet). Since 1965, bikesharing has grown across the globe on four continents including: Europe, North America, South America, and Asia (including Australia). Today, there are approximately 100 bikesharing programs operating in an estimated 125 cities around the world with over 139,300 bicycles. Bikesharing’s evolution is categorized into three generations: 1) White Bikes (or Free Bike Systems); 2) Coin-Deposit Systems; and 3) IT-Based Systems. In this paper, the authors propose a fourth-generation: “Demand-Responsive, Multi-Modal Systems.” A range of existing bikesharing business models (e.g., advertising) and lessons learned are discussed including: 1) bicycle theft and vandalism; 2) bicycle redistribution; 3) information systems (e.g., real-time information); 4) insurance and liability concerns; and 5) pre-launch considerations. While limited in number, several studies have documented bikesharing’s social and environmental benefits including reduced auto use, increased bicycle use, and a growing awareness of bikesharing as a daily mobility option. Despite bikesharing’s ongoing growth, obstacles and uncertainty remain, including: future demand; safety; sustainability of business models; limited cycling infrastructure; challenges to integrating with public transportation systems; technology costs; and user convenience (e.g., limited height adjustment on bicycles, lack of cargo space, and exposure to weather conditions). In the future, more research is needed to better understand bikesharing’s impacts, operations, and business models in light of its reported growth and benefits. View...

Innovative Mobility Carsharing Outlook – Winter 2018

Authors: Susan Shaheen, PhD, Adam Cohen, and Mark Jaffee Date: February, 2018 Abstract: Peer-to-peer (P2P) carsharing employs privately owned vehicles made temporarily available for shared use by an individual or members of a P2P carsharing network. Expenditures, such as insurance, are generally covered by the P2P operator during the access period. In exchange for providing the service, operators keep a portion of the usage fee. Members can access vehicles through a direct key or combination transfer from the owner or through operator-installed technology that enables “unattended access.” Although P2P carsharing is more commonplace in the United Kingdom, Netherlands, Germany, and other parts of Europe, the market continues to grow steadily in North America. For instance, the P2P carsharing operator, Turo, expanded into Canada in April 2017, becoming the first American P2P operator to enter an international market....

Innovation in Mobility Public Policy Summit Agenda – June 2014

Tuesday, June 10, 2014 8:30 AM                Networking Breakfast 9:00 AM                Welcome to Washington 9:30 AM                Call to Charge – The Honorable Earl Blumenauer, Member of Congress (D-OR) 9:45 AM                Plenary Session | Setting the Stage: What’s New in Shared-Use Mobility? Jump-start the conference by learning about the latest trends in shared-use mobility and its impacts on our local communities. Experts in the shared-use mobility field review generational trends (e.g., Baby Boomers, Millennials) that shape the way we travel, give their perspectives on the latest mobility developments, and set the stage for an in-depth analysis of emerging issues. 10:45 AM             Morning Break 11:00 AM             Plenary Session | You Complete Me: Partnering with Public Transit to Complete the Transportation System Integration of shared-use modes into a local government’s suite of services is integral to putting together a truly multi-modal transportation system. In this session, hear transportation organizations discuss the impact of innovative mobility options on their operations and how they promote and integrate these services to enhance the rider experience. This session will actively address how shared-use operators can fill gaps and extend the reach of current systems. 12:15 PM              Lunch Keynote |  Breaking Down Modal Walls How Utah Transit Authority Has Help Pave a Path to Shared Success… 1:30 PM              Breakout Session 1 Federal Funding & Policies Track Show Me the Money.” What federal resources are available for shared-use operators, and how can you access these funds?  Want to know how to get Federal transportation funds for your project? This session will show you how. Federal transportation funding makes up a majority of all...
