Understanding Transit System Performance Using Avl-Apc Data: An Analytics Platform With Case Studies For The Pittsburgh Region, Xidong Pi, Mark Egge, Jackson Whitmore, Amy Silbermann, Zhen Sean Qian
Journal of Public Transportation
This paper introduces a novel transit data analytics platform for public transit planning, assessing service quality and revealing service problems in high spatiotemporal resolution for public transit systems based on Automatic Passenger Counting (APC) and Automatic Vehicle Location (AVL) technologies. The platform offers a systematic way for users and decision makers to understand system performance from many aspects of service quality, including passenger waiting time, stop-skipping frequency, bus bunching level, bus travel time, on-time performance, and bus fullness. The AVL-APC data from September 2012 to March 2016 were archived in a database to support the development of a user-friendly web …

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
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 …

Journal of Public Transportation
This paper discusses the implications of autonomous vehicle technology on auto use and travel behavior, and the resulting impacts on public transportation. The paper goes on to explore how autonomous driving technology can make more efficient use of bus transportation and improve service to disabled individuals. The paper concludes with recommendations for transit agencies to engage with government and suppliers of autonomous vehicles to promote research, development, and policies that will allow the industry to reap the benefits of this revolutionary and disruptive technology.
Analysis On The Influence Factors Of Accident Severity: Evidence From Urban River-Crossing Tunnels In Shanghai Of China, Wan He, Zhuoye Zhang, Linjun Lu, Zhenyu Wang
Analysis On The Influence Factors Of Accident Severity: Evidence From Urban River-Crossing Tunnels In Shanghai Of China, Wan He, Zhuoye Zhang, Linjun Lu, Zhenyu Wang
CUTR Faculty Journal Publications
To analyze various factors influencing the accident severity of urban river-crossing tunnels, 12 influence factors were selected according to the three traffic elements of vehicle, road, and environment, including accident-involved vehicle type, tunnel length, tunnel speed limit, accident occurrence time, and weather. These factors were based on the historical data of 14 urban river-crossing tunnels in Shanghai. A binary logistic regression model was also utilized to identify significant influence factors and analyze the influence degrees of their accident severity. Significance analysis reveals that accident occurrence place, accident-involved vehicle type, tunnel speed limit, number of vehicles involved, and accident type are …
Can Public Transportation Compete With Automated And Connected Cars?, Ralph Buehler
Can Public Transportation Compete With Automated And Connected Cars?, Ralph Buehler
Journal of Public Transportation
Over the next 30 years, technological innovation will make automobile travel more convenient. Automated and connected vehicles will perform an increasing number of driving tasks without human input and will lure customers away from traditional public transportation. This paper first explores key characteristics of public transportation demand in the United States today--based on an international comparison with other Western countries. Next, the paper provides potential pathways on how public transportation agencies and local governments in the United States could respond to the emergence of automated and connected vehicles. The paper argues that space efficiency in urbanized areas and the rush …

Lies, Damned Lies, Avs, Shared Mobility, And Urban Transit Futures, Graham Currie
Journal of Public Transportation
It seems to me there is a gigantic lot of nonsense discussed about the future of transport and the future of public transport in particular. As a researcher in the field, I find my emotions boiling over. I get angry at blanket statements telling us public transport has no future and it seems to me much of what is talked about regarding transport futures flies in the face of facts and a long history of what knowledge has gleaned about the human condition, economics, cities, and travel. My hope is that readers will see prevailing discourse differently as a result …
Future Of Rural Transit, Jill Hough, Ali Rahim Taleqani
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 …

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?

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

A Synthesis Of Mobile Ticketing Applications Used By Commuter Railroads In The United States, Jonathan Mesoraca, Candace Brakewood
A Synthesis Of Mobile Ticketing Applications Used By Commuter Railroads In The United States, Jonathan Mesoraca, Candace Brakewood
Journal of Public Transportation
Since 2012, many major commuter railroads have deployed mobile ticketing applications (or “apps”) that allow passengers to pay fares directly using their smartphones. In light of this rapid technological change, this research aims to provide a synthesis of the current state of mobile ticketing in the United States. The 14 largest commuter railroads that have launched mobile ticketing apps are compared in four different areas: (1) the ticket validation process; (2) ticket types offered in the mobile app; (3) additional features in the app; and (4) the process for transferring to other modes using the app. The results reveal that …

Ex-Regular Users Of Public Transport: Their Reasons For Leaving And Returning, Paula Vicente, Elizabeth Reis
Journal of Public Transportation
This paper describes the characteristics of former regular users of public transport in the metropolitan area of Lisbon. It also examines why these people stopped using public transport and explores what would make them become regular users again. The empirical results revealed significant socio-demographic differences between current and ex-regular users, namely in relation to gender and social level. Differences were also found in travel characteristics, car ownership, and satisfaction with the transit service. The main reasons given by ex-regular users for no longer using public transport included changes in their lives (e.g., change in workplace/residence/ school or becoming unemployed) and …
