Does The Future Of Mobility Depend On Public Transportation?, Kari Watkins

Journal of Public Transportation

We’ve all seen the headlines. “Will self-driving cars, taxis make mass transit obsolete?” (Davidson 2017) and “What happens if Uber or Lyft outcompetes public transit?” (Sen 2017) or even “Department Of Transportation Says The Future Of Transit Looks Pretty Bleak” (Griggs 2015). We are entering the next great revolution in how people move about in cities. But does the future of transportation mean the end of transit?

Future Of Rural Transit, Jill Hough, Ali Rahim Taleqani 2018 Upper Great Plains Transportation Institute, North Dakota State University

Future Of Rural Transit, Jill Hough, Ali Rahim Taleqani

Journal of Public Transportation

This paper provides a contemplative description of the future of rural public transportation. It considers emerging technologies along with their long-term implications and corresponding impacts on rural communities. The authors used their collective knowledge to identify key drivers of change in rural areas. As a result, the authors expect the future definition of rural areas to change and a new geographical classification to emerge. This classification is a continuum of population density gradient from highly populated urban areas to sparsely populated areas. The paper also suggests that automated vehicles and hologram telecommuting could dominate the U.S. transportation industry, even in …

Is It Time For A Public Transit Renaissance?: Navigating Travel Behavior, Technology, And Business Model Shifts In A Brave New World, Susan Shaheen, Adam Cohen 2018 University of California, Berkeley

Is It Time For A Public Transit Renaissance?: Navigating Travel Behavior, Technology, And Business Model Shifts In A Brave New World, Susan Shaheen, Adam Cohen

Journal of Public Transportation

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 …


Transit In The 2000s: Where Does It Stand And Where Is It Headed?, Michael Manville, Brian D. Taylor, Evelyn Blumenberg 2018 UCLA Luskin School of Public Affairs

Transit In The 2000s: Where Does It Stand And Where Is It Headed?, Michael Manville, Brian D. Taylor, Evelyn Blumenberg

Journal of Public Transportation

U.S. public transit has experienced something of a renaissance in the 2000s, with per capita service levels increasing nationwide and public investment growing even faster—particularly expenditures on rail transit. Despite this expansion, overall transit patronage has been relatively flat, and has declined significantly since 2014. What is behind these trends, and what do they portend for the future of transit? In this paper we consider three challenges shaping transit today and in the years ahead: (1) the asymmetry of transit supply and use make it especially vulnerable to changes and disruptions; (2) many of the factors that determine transit ridership, …
