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

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 ...


Evaluation Of A Supervisor Training Program For Odot’S Ecodrive Program, Donald M. Truxillo, John MacArthur, Leslie B. Hammer, Talya N. Bauer 2017 Portland State University

Evaluation Of A Supervisor Training Program For Odot’S Ecodrive Program, Donald M. Truxillo, John Macarthur, Leslie B. Hammer, Talya N. Bauer

Eco-driving consists of using energy-efficient approaches to driving aimed at reducing fuel consumption and, ultimately, CO2 emissions. A previous study found that an EcoDrive informational campaign was effective at increasing the use of eco-driving behaviors, but only when employees perceived that their supervisor supported the program and when they were personally motivated to perform the eco-driving behaviors. In order to build upon the findings of our previous study, the present study focused on increasing the use of eco-driving behaviors through an informational eco-driving campaign combined with supervisor training to support the use of eco-driving practices.

In this study we collected ...

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 ...


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 ...
