2012

Carsharing (or short-term auto use) provides a flexible alternative that meets diverse transportation needs across the globe, while reducing the negative impacts of private vehicle ownership. More than 65 years ago, carsharing began appearing in Europe. It has expanded to approximately 1,100 cities worldwide, in 26 nations on five continents. This article provides a global perspective of carsharing growth and future developments from 2006 through 2015, employing data from three surveys conducted in 2006, 2008, and 2010. The authors explore the interview findings of 25 carsharing experts...

Bikesharing across the Globe

Guzman, Stacey

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...

Public Bikesharing in North America: Early Operator Understanding and Emerging Trends

Public bikesharing—the shared use of a bicycle fleet by the public—is an innovative mobility strategy that has recently emerged in major North American cities. Bikesharing systems typically position bicycles throughout an urban environment, among a network of docking stations, for immediate access. Approximately five years ago, information technology (or IT)-based bikesharing services began to emerge in North America. Between 2007 and March 2013, 28 IT-based programs have been deployed–24 are operational, two are temporarily suspended, and two are now defunct in the United States (U.S.)...

Exploring the Future of Integrated Transportation Systems in the United States from 2030 to 2050: Application of a Scenario Planning Tool

Intelligent transportation systems (ITS) have primarily focused on systems management. To further improve connectivity and safety in the future, ITS might embrace a more holistic planning approach. While the future of ITS remains an open question, its evolution is closely linked to how the world evolves on many dimensions, social, political, economic, legal, and environmental. In this paper, the authors present results from four expert workshops. These consisted of an initial steering committee workshop (February 2011), two expert scenario-planning workshops (June 2011), and a final...

Bicycle Evolution in China: From the 1900s to the Present

Zhang, Hua
Susan Shaheen
Chen, Xingpeng
2013

This article examines four phases in bicycle evolution in China from initial entry and slow growth (1900s to 1978), to rapid growth (1978 to 1995), bicycle use reduction (1995 to 2002), and policy diversification (2002 to present). Two bicycle innovations, electric bikes, and public bikesharing (the shared use of a bicycle fleet), are also explored in this article. Electric bikes could provide a transitional mode on the pathway to bicycle and public transportation integration or to small battery electric cars. Four lessons have been learned from China’s electric bike experience relevant to...

Understanding the Diffusion of Public Bikesharing Systems: Evidence from Europe and North America

2013

Since the mid-2000s, public bikesharing (also known as ‘‘bike hire’’) has developed and spread into a new form of mobility in cities across the globe. This paper presents an analysis of the recent increase in the number of public bikesharing systems. Bikesharing is the shared use of a bicycle fleet, which is accessible to the public and serves as a form of public transportation. The initial system designs were pioneered in Europe and, after a series of technological innovations, appear to have matured into a system experiencing widespread adoption. There are also signs that the policy of...

Intelligent Transportation Systems

2013

Intelligent transportation systems (ITS) represent a group of technologies that can improve transportation system management and public transit, as well as individual decisions surrounding many aspects of travel. ITS technologies include state-of-the art wireless, electronic, and automated technologies with a goal to improve surface transportation safety, efficiency, and convenience. Reducing energy consumption, while not a primary goal for ITS, is a demonstrated ITS benefit in certain circumstances. This paper reviews and summarizes key energy benefits associated with a variety of ITS...

Public Bikesharing and Modal Shift Behavior: A Comparative Study of Early Bikesharing Systems in North America

Susan Shaheen
Martin, Elliot, PhD
Cohen, Adam
2013

Public bikesharing—the shared use of a bicycle fleet by the public—is an innovative mobility strategy that has recently emerged in major North American cities. Bikesharing systems typically position bicycles throughout an urban environment, among a network of docking stations, for immediate access. This paper discusses the modal shift that results from individuals participating in four public bikesharing systems in North America. The authors conducted an online survey (n =10,661 total sample), between November 2011 and January 2012, with members of four major bikesharing organizations (...

Peer-To-Peer (P2P) Carsharing: Exploring Public Perception and Market Characteristics in the San Francisco Bay Area

Peer-to-peer (P2P) carsharing is an innovative approach to vehicle sharing in which vehicle owners temporarily rent their personal automobiles to others in their surrounding area. P2P carsharing belongs to the larger sharing economy, an economic model premised on the notion of collaborative consumption as opposed to ownership. This study examines current public perception of P2P carsharing and potential market characteristics through an intercept survey conducted in the San Francisco Bay Area. Three hundred respondents from 14 locations in San Francisco (N=150) and Oakland (N=150) were...

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

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 within California and evaluates the...
