California Transportation Plan 2050: Northern and Southern California Visioning Sessions Findings

Authors: Susan Shaheen, PhD, Hannah Totte, Adam Cohen Date: December 2018 Abstract: Improving California’s transportation system requires cross-sector collaboration, particularly as technologies, policies, and regulations develop simultaneously. The California Transportation Plan (CTP) 2050 aims to integrate perspectives a diverse array of stakeholder perspectives that may not typically participate in the statewide planning process. The Visioning Sessions facilitated two day-long visioning workshops in October 2018 in Southern and Northern California. Overall, these visioning sessions initiated a much-needed dialogue among experts and practitioners from diverse backgrounds and allowed participants to conceptualize idealized visions for California’s transportation system through 2050. Key goals of the visioning sessions included: 1. Developing visions for CTP2050 incorporating diverse perspectives from an array of statewide stakeholders including private and public sector, academic, and non-profit experts; 2. Identifying existing and policy and investment strategies to actualize the idealized states; and 3. Translating high-level policy and investment suggestions into actionable items. View...

Shared-Use Vehicle Services for Sustainable Transportation: Carsharing, Bikesharing, and Personal Vehicle Sharing Across the Globe

Authors: Susan Shaheen, PhD Date: June 2012 Abstract: This special issue of the International Journal of Sustainable Transportation highlights developments in shared-use vehicle research, in particular carsharing, public bikesharing, and personal vehicle sharing. Since the mid-1980s, shared-use vehicle services have gained momentum across the world. Developments include a range of operational models—private, non-profit, and governmental ventures; advanced technology; worldwide entry and growth; collaboration and competition; and increased activity by auto rental companies and automakers.

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

Authors: Stephen Parkes, Greg Mardsen, Susan Shaheen, PhD, Adam Cohen Date: July 2013 Abstract: 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 public bikesharing systems is transferable and is being adopted in other contexts outside Europe. In public policy, the technologies that are transferred can be policies, technologies, ideals or systems. This paper seeks to describe the nature of these systems, how they have spread in time and space, how they have matured in different contexts, and why they have been adopted. Researchers provide an analysis from Europe and North America. The analysis draws on published data sources, a survey of 19 systems, and interviews with 12 decision-makers in Europe and 14 decision-makers in North America. The data are examined through the lens of diffusion theory, which allows for comparison of the adoption process in different contexts. A mixture of quantitative and qualitative analyses is used to explore the reasons for adoption decisions in different cities. The paper concludes that Europe is still in a major adoption process with new systems emerging and growth in some existing systems, although some geographic...

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

Authors: Hua Zhang, Susan Shaheen, PhD, Xingpeng Chen Date: October 2013 Abstract: 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 government policy and management. Public bikesharing represents an important step towards integrating the bicycle with bus, metro, and rail systems. Five early operational lessons have been identified from China’s limited public bikesharing experience. View...

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

Authors: Susan Shaheen, PhD, Madonna Camel, Kunik Lee Date: March 2013 Abstract: 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 dimensions¾social, 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 steering committee workshop (July 2011). The scenario planning workshops explored the implications of alternative futures on ITS and incorporated a broad interdisciplinary approach in developing a long-term transportation vision (2030 to 2050 time horizon) for the United States. Twenty-four experts, representing diverse disciplines, participated in a series of workshops to envision plausible futures and to assess their effects on the transportation system. By exploring different futures, experts identified opportunities and barriers for implementing advanced seamless transportation systems. Opportunities included the deployment of adaptable, integrated technology and transportation infrastructure to address natural disasters and climate change. The most significant barriers were funding and politics. The experts suggested that financial barriers be overcome through innovative funding techniques and improved public outreach. Building upon the experts’ recommendations, several visions for an integrated ITS approach, which addresses social and environmental challenges in the future, were created. These included private-public partnerships; distributed implementation models (e.g., localized); and the development of seamless transportation systems to reduce energy consumption, emissions, and road congestion.
