Is It Time for a Public Transit Renaissance?

Authors: Susan Shaheen, PhD and Adam Cohen Date: March 15, 2018 Abstract: Travel behavior is undergoing a period of significant change in the United States. In 2016, public transit ridership fell in almost all major U.S. metropolitan regions. While Americans are still heavily dependent on the personal automobile for mobility, technological and societal changes are transforming how mobility is accomplished. This paper reviews the convergence of five trends leading to fundamental changes in public transportation: (1) changing generational behavior toward suburbanization and automobility; (2) new attitudes toward information communications technology; (3) shifting attitudes toward sharing and mobility on demand; (4) innovative alternatives to work and non-work travel; and (5) an increasing number of on-demand flexible route transportation options. The paper concludes with recommendations and guiding principles for public agencies to consider in responding to these trends. View...

Policy Brief: Impacts of Shared Mobility, Pooling

Authors: Susan Shaheen, PhD and Adam Cohen Date: January, 2018 Abstract: Shared-ride services—transportation modes that allow riders to share a ride to a common destination—include various forms of ridesharing (carpooling and vanpooling); ridesplitting and taxisplitting; and microtransit. With the proliferation of smartphones and mobile Internet, it has become more convenient to share rides. Shared-ride services are having a transformative impact on many global cities by increasing vehicle occupancy through smartphone apps.   View...

Policy Brief: Smartphone Applications and Data Impacting Transportation

Authors: Susan Shaheen, PhD and Adam Cohen Date: January, 2018 Abstract: Demographic shifts, improvements in computing power and mapping technology, the use of cloud computing, and changes in wireless communication — coupled with the growth of data availability and data sharing — are changing the way people travel. Increasingly, mobility consumers are turning to smartphone “apps” for a wide array of transportation activities including: vehicle routing, real-time data on congestion, information regarding roadway incidents and construction, parking availability, and real-time transit arrival predictions. Travel time savings (e.g., high occupancy vehicle lanes available to users of shared-ride services); financial savings (e.g., dynamic pricing providing discounts for peak and off-peak travel and for choosing low-volume routes); incentives (e.g., offering points, discounts, or lotteries); and gamification (e.g., use of game design elements in a non-game context) are among the key factors driving end-user growth of smartphone transportation applications.   View...

Travel Behavior: Shared Mobility and Transportation Equity

Authors: Susan Shaheen, PhD, Corwin Bell, Adam Cohen, Balaji Yelchuru Date: August 2017 Abstract: Shared mobility—the shared use of a motor vehicle, bicycle, or other low-speed transportation mode that allows users to obtain short-term access to transportation on an as-needed basis—has the potential to help address some transportation equity challenges. In an effort to categorize the myriad of transportation equity barriers facing transportation system users, this primer proposes a ‘STEPS to Transportation Equity’ framework including: Spatial, Temporal, Economic, Physiological, and Social barriers. For each barrier category, shared mobility opportunities and challenges are explored along with policy recommendations. View...

Planning for Shared Mobility

Authors: Susan Shaheen, PhD, Adam Cohen Date: July 26, 2016 Abstract: 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 modes—such as bikesharing, carsharing, ridesourcing, and alternative transit services—are changing how people travel and are having a transformative effect on mobility and local planning.
