Access To Taxicabs For Unbanked Households: An Exploratory Analysis In New York City, David A. King, Juan Francisco Saldarriaga 2017 Columbia University

Access To Taxicabs For Unbanked Households: An Exploratory Analysis In New York City, David A. King, Juan Francisco Saldarriaga

Journal of Public Transportation

Taxicabs are critical complements to public transit systems. In New York City, ubiquitous yellow cabs are as iconic as the city’s subway system, and the city recently added green taxicabs to improve taxi service in areas outside of the Central Business Districts and airports. In this paper, we used multiple datasets to explore taxicab fare payments by neighborhood and examine how paid taxicab fares are associated with use of conventional banking services. There are clear spatial dimensions of the propensity of riders to pay cash, and we found that both immigrant status and being “unbanked” are strong predictors of ...


Measuring The Accuracy Of Bus Rapid Transit Forecasts, John Perry 2017 None

Measuring The Accuracy Of Bus Rapid Transit Forecasts, John Perry

Journal of Public Transportation

The research of Dr. Bent Flyvbjerg in the 1990s and early 2000s showed that urban rail projects often cost more than estimated and carried fewer riders than projected, a troubling trend suggesting that the forecasts for urban rail projects were too optimistic in terms of cost and ridership. Inspired by that research, this analysis seeks to extend that framework to analyze Bus Rapid Transit (BRT). A study of forecast vs. actual costs and ridership was conducted for 19 BRT projects in the United States. From this, it was found that the cost projections for these projects tended to be quite ...


Identifying Key Factors Of Rail Transit Service Quality: An Empirical Analysis For Istanbul, Erkan Isikli, Nezir Aydin, Erkan Celik, Alev Taskin Gumus 2017 Istanbul Technical University

Identifying Key Factors Of Rail Transit Service Quality: An Empirical Analysis For Istanbul, Erkan Isikli, Nezir Aydin, Erkan Celik, Alev Taskin Gumus

Journal of Public Transportation

Providing a high quality of service in public transportation is essential to reduce dissatisfactions stemming from traffic congestion and noise. Public transport providers need to find ways to dilute the effects of immoderate use of private cars in big cities while maintaining a sufficient level of customer satisfaction. This study aimed to identify the key service quality (SQ) factors that drive passenger satisfaction in Istanbul’s rail transit (RT) system using data obtained from an extensive survey conducted by the Istanbul Public Transportation Co. A total of 11,116 passengers who used rail transport from May 15–June 3, 2012 ...


Effect Of Price Reduction And Increased Service Frequency On Public Transport Travel, Inge Brechan 2017 Institute of Transport Economics, Oslo

Effect Of Price Reduction And Increased Service Frequency On Public Transport Travel, Inge Brechan

Journal of Public Transportation

A random effects meta-analysis of the results from 15 projects involving price reduction and 9 projects involving increased service frequency showed that both price reduction and increased service frequency generated public transport travels. On average, the increased service frequency projects generated more travels by public transport than the price reduction projects. In the increased service frequency projects the proportion of travels generated by the increased frequency was strongly influenced by the size of the frequency increase. In the price reduction projects, we did not find a significant effect of the size of the price reduction on the proportion of travels ...


The Causal Effect Of Bus Rapid Transit On Changes In Transit Ridership, Orion T. Stewart, Anne Vernez Moudon, Brian E. Saelens 2017 University of Washington

The Causal Effect Of Bus Rapid Transit On Changes In Transit Ridership, Orion T. Stewart, Anne Vernez Moudon, Brian E. Saelens

Journal of Public Transportation

Numerous studies have reported ridership increases along routes when Bus rapid transit (BRT) replaces conventional bus service, but these increases could be due simply to broader temporal trends in transit ridership. To address this limitation, we compared changes in ridership among routes where BRT was implemented to routes where BRT was planned or already existed in King County, Washington. Ridership was measured at 2010, 2013, and 2014. Ridership increased by 35% along routes where BRT was implemented from 2010 to 2013 compared to routes that maintained conventional bus service. Ridership increased by 29% along routes where BRT was implemented from ...

Transit agencies are interested in assessing the short-, mid-, and long-term performance of infrastructure with the objective of enhancing resiliency and efficiency. This report addresses three distinct aspects of New Jersey’s Transit System: 1) resiliency of bridge infrastructure, 2) resiliency of public transit systems, and 3) efficiency of transit systems with an emphasis on paratransit service.

This project proposed a conceptual framework to assess the performance and resiliency for bridge structures in a transit network before and after disasters utilizing structural health monitoring (SHM), finite element (FE) modeling and remote sensing using Interferometric Synthetic Aperture Radar (InSAR). The public ...

Exploring The Positive Utility Of Travel And Mode Choice, Patrick Allen Singleton 2017 Portland State University

Exploring The Positive Utility Of Travel And Mode Choice, Patrick Allen Singleton

TREC Friday Seminar Series

Why do people travel? We traditionally assume traveling is a means to an end, travel demand is derived (from the demand for activities), and travel time is to be minimized. Recently, scholars have questioned these axioms, noting that some people may like to travel, use travel time productively, enjoy the experience of traveling, or travel for non-utilitarian reasons. The idea that travel can provide benefits and may be motivated by factors beyond reaching activity destinations is known as “the positive utility of travel” or PUT.

This study presents a conceptual and empirical look at the positive utility of travel and ...

Addressing The Supportive Transportation Challenges Of Community-Residing Older Adults, Nina M. Silverstein, Kristina M. Turk, Laura Adams, Holly Belanger, Linnea Burke, Stephen Jones, Lauren Lee, David Lopez, Keith Sherman, Lee Paradis, Erin O’Neill, Alycia Rao, Rachael Solano

Nina Silverstein

The ability to get to where you want to go, when you want to go there is a key factor for aging-in-place in our communities. It is often taken for granted until that ability is compromised. The informal network of family and friends, if it exists, is not likely to be a sustainable transportation alternative for persons with cognitive impairment or for older adults with limitations that may not fit eligibility criteria for senior transportation services, where they exist. The purpose of this study was to investigate the potential of communities to address the specialized supportive mobility needs of community-residing ...


Individual Decision Making In Online Public-Participation Transportation Planning, Martin Swobodzinski 2017 Portland State University

Individual Decision Making In Online Public-Participation Transportation Planning, Martin Swobodzinski

TREC Friday Seminar Series

The empirical evaluation of complex decision support systems is often limited to the self-reported satisfaction of the systems’ users.

Such an approach is problematic due to the conflation of the user's satisfaction related to the decision support system and the decision making process and its outcomes.

In addition, it bears limitations that are common among most techniques that solicit participant-stated feedback.

In this talk, based on data that was gathered by a web-based participatory system for transportation planning in the Puget Sound region, I present analytical methods for the empirical evaluation of decision support systems based on human-computer interaction ...


A Comparative Analysis Of High-Speed Rail Station Development Into Destination And Multi-Use Facilities: The Case Of San Jose Diridon, Anastasia Loukaitou-Sideris, Deike Peters, Paige Colton, Eric Eidlin 2017 University of California, Los Angeles

A Comparative Analysis Of High-Speed Rail Station Development Into Destination And Multi-Use Facilities: The Case Of San Jose Diridon, Anastasia Loukaitou-Sideris, Deike Peters, Paige Colton, Eric Eidlin

Mineta Transportation Institute Publications

As a burgeoning literature on high-speed rail development indicates, good station-area planning is a very important prerequisite for the eventual successful operation of a high-speed rail station; it can also trigger opportunities for economic development in the station area and the station-city. At the same time, “on the ground” experiences from international examples of high-speed rail stations can provide valuable lessons for the California high-speed rail system in general, and the San Jose Diridon station in particular. This study identifies and draws lessons from European HSR stations that share similarities across several criteria with the San Jose area context. From ...


The Challenge Of Protecting Transit And Passenger Rail: Understanding How Security Works Against Terrorism, Brian Michael Jenkins 2017 National Transportation Safety and Security Center, Mineta Transportation Institute

The Challenge Of Protecting Transit And Passenger Rail: Understanding How Security Works Against Terrorism, Brian Michael Jenkins

Mineta Transportation Institute Publications

Terrorists see transit and passenger rail as an attractive target. Designed for public convenience, trains and stations offer terrorists easy access to crowds of people in confined environments where there are minimal security risks and attacks can cause high casualties. This report examines the unique attributes of the terrorist threat, how security measures against terrorism have evolved over the years, and their overall effectiveness.

Does security work? Empirical evidence is hard to come by. Terrorist incidents are statistically rare and random, making it difficult to discern effects. The fact that terrorists focus most of their attacks on targets with little ...

Improving Trip Generation Methods For Livable Communities, Kelly Clifton, Nico Larco, Kristina Marie Currans, Jael Wettach-Glosser

TREC Final Reports

Recent efforts to improve trip generation data available for transportation impact analysis of new development include the collection of multimodal trip generation data, development of models that account for the built environment, and new recommendations for practice. Building on a long line of research on transportation and built environment, many studies have identified important features of the surrounding built environment that most impact trip rates and mode shares, building on a long line of research on transportation and the built environment. Despite these improvements in data and methods, less attention is placed on identifying the conditions of the site itself ...

Evaluation Of An Electric Bike Pilot Project At Three Employment Campuses In Portland, Oregon, John Macarthur, Nicholas Kobel, Jennifer Dill, Zakari Mumuni

TREC Final Reports

Oregon, and Portland in particular, is internationally known for its love for bikes. Not only does the region have some of the highest bike ridership but the Oregon bike manufacturing industry is quickly growing. Oregon’s electric bike (e-bike) market is also growing but little data are available on the potential market and e-bike user behavior and interest. Only a limited amount of research has explored the potential new market segments for e-bikes and the economic, operational, safety, and transportation issues surrounding e-bikes in the United States. This report examines the results of an electric bike (e-bike) pilot project, which ...

Estimating Reliability Indices And Confidence Intervals For Transit And Traffic At The Corridor Level, Travis B. Glick 2017 Portland State University

Estimating Reliability Indices And Confidence Intervals For Transit And Traffic At The Corridor Level, Travis B. Glick

TREC Friday Seminar Series

As congestion worsens, the importance of rigorous methodologies to estimate travel-time reliability increases. Exploiting fine-granularity transit GPS data, this research proposes a novel method to estimate travel-time percentiles and confidence intervals. Novel transit reliability measures based on travel-time percentiles are proposed to identify and rank low-performance hotspots; the proposed reliability measures can be utilized to distinguish peak-hour low performance from whole-day low performance. As a case study, the methodology is applied to a bus transit corridor in Portland, Oregon. Time-space speed profiles, heatmaps, and visualizations are employed to highlight sections and intersections with high travel-time variability and transit low performance ...


Current Efforts To Make Bike Share More Equitable: A Survey Of System Owners And Operators, Steven Howland 2017 Portland State University

Current Efforts To Make Bike Share More Equitable: A Survey Of System Owners And Operators, Steven Howland

TREC Friday Seminar Series

The number of public bike share systems has been increasing rapidly across the United States over the past five to ten years. To date most academic research around bike share in the U.S. has focused on the logistics of planning and operationalizing successful systems. Investigations of system users and impacts on the local community are less common, and studies focused on efforts to engage underserved communities in bike share are rarer still. This paper utilizes a survey of representatives from 55 U.S. bike share systems to better understand and document current approaches toward serving low income and minority ...


Webinar: Improving Walkability At Signalized Intersections With Signal Control Strategies, Edward J. Smaglik, Sirisha Murthy Kothuri 2017 Northern Arizona University

Webinar: Improving Walkability At Signalized Intersections With Signal Control Strategies, Edward J. Smaglik, Sirisha Murthy Kothuri

TREC Webinar Series

The goal of signal timing at an intersection should be to maximize efficiency for all users. In many jurisdictions, however, traffic signals are timed mostly with the goal of reducing vehicular delay.

Other road users, such as pedestrians, deserve similar focus. In legacy transportation systems, pedestrians experience delays much in excess of those that would be deemed acceptable for a motor vehicle at the same location.

Excessive delay can lead to pedestrian frustration, non-compliance and ultimately decreased safety.

In the North American context, implementation of strategies to address pedestrian service varies greatly across jurisdictions, and there has been limited research ...
