The Effects Of Gateway Width On Driver Yielding To Pedestrians: A Systematic And Parametric Analysis, Jonathan M. Hochmuth 2018 Western Michigan University

The Effects Of Gateway Width On Driver Yielding To Pedestrians: A Systematic And Parametric Analysis, Jonathan M. Hochmuth

Master's Theses

The gateway in-street sign treatment has been demonstrated to be a cost-effective method for increasing driver yielding behavior at crosswalks. In the present study, wide and narrow gateway widths were compared at two sites to determine if there was a differential effect on driver yielding behavior. Then, the relationship between width and yielding was refined with a parametric analysis at one of these sites. Gateway width was varied in two-foot intervals from 12ft to 18ft. The results indicated an inverse relationship between gateway width and driver yielding behavior. There are likely two variables related to this effect. First, because drivers ...

Who Wins And Who Loses? How Gentrification Caused By Public Transportation Is Felt Differently Across Race, Rosina Shipman 2018 Ursinus College

Who Wins And Who Loses? How Gentrification Caused By Public Transportation Is Felt Differently Across Race, Rosina Shipman

Politics Summer Fellows

When does a public good become harmful? And who does it harm? To tackle these questions I take a detailed look at how public transportation affects housing prices. Public transportation is a common good utilized by people of all different socioeconomic levels, but scholars have found that the presence of a new public transportation stop can be a catalyst for gentrification, raising housing prices and displacing previous residents. While this positive relationship between housing prices and public transportation is well documented, there is a lack of literature on how gentrification, caused by public transportation, affects neighborhood-housing prices across race. In ...

Policy Options For Improving The Resilience Of Us Transportation Infrastructure, Gina Tonn Ms., Jeffrey Czajkowski, Howard Kunreuther 2018 University of Pennsylvania

Policy Options For Improving The Resilience Of Us Transportation Infrastructure, Gina Tonn Ms., Jeffrey Czajkowski, Howard Kunreuther

Penn Wharton Public Policy Initiative

Despite the vulnerability of America’s aging infrastructure to costly disruptions from man-made and natural disasters, infrastructure insurance under-utilized. On average, only 30% of catastrophic losses in the past 10 years have been covered by insurance. Most infrastructure project managers have relied instead on taxpayer-funded federal aid when disaster strikes. But it doesn’t need to be this way. In this brief, Gina Tonn, Jeffrey Czajkowski, and Howard Kunreuther use technical reports and input from infrastructure managers to outline steps that policymakers can take to help maximize the use of infrastructure insurance for providing financial protection, encouraging investment in loss ...

Train Wrecks And Track Attacks: An Analysis Of Attempts By Terrorists And Other Extremists To Derail Trains Or Disrupt Rail Transportation, Brian Michael Jenkins, Bruce R. Butterworth

Mineta Transportation Institute Publications

Attempts to sabotage rails and deliberately derail passenger trains have a long history in conventional and guerrilla warfare as well as during some particularly bitter labor disputes in the past. Since the 1970s, political fanatics have become a major adversary. Terrorists have sought to derail trains to achieve high-casualty events, while anarchists and issue oriented extremists have attacked rails to attract attention to their causes and impose economic damage. In this report, we examine the more than a thousand attempts to derail trains and to attack rail infrastructure to discern overall patterns and trends. We then look at four subsets ...

Integrated Performance Measures: Transit Equity & Efficiency, Ran Wei, Aaron Golub, Liming Wang, Thomas Cova

TREC Project Briefs

Assessing the performance of public transit services has long been an important yet challenging issue for transportation agencies and researchers. Transit service performance measurement reflects a very first step towards an efficient and proactive management, where public transit agencies are increasingly pressured to provide high-quality services in spite of constrained resources. However, the performance evaluation of transit services is complicated by an array of quantitative measures available to assess the goals and the diversity in the goals themselves, which usually include improving operational efficiency and providing equitable access. While much previous work has examined public transit services for achieving optimal ...

Exploring Transit’S Contribution To Livability In Rural Communities: Case Studies Of The North Dakota Cities Of Valley City And Dickinson, Ranjit Godavarthy, Jeremy Mattson 2018 North Dakota State University

Exploring Transit’S Contribution To Livability In Rural Communities: Case Studies Of The North Dakota Cities Of Valley City And Dickinson, Ranjit Godavarthy, Jeremy Mattson

Journal of Public Transportation

This paper investigates the nexus of transit and rural livability as demonstrated by case studies in the North Dakota communities of Valley City and Dickinson. While there are many factors that influence the livability of a rural community, transit is believed to be an important contributor. For each of the two North Dakota communities considered, public/resident surveys, local transit rider surveys, and stakeholder interviews were conducted to understand differing opinions on livability and how transit contributes to livability.

In both Valley City and Dickinson, surveys of residents showed that they believe affordable housing, low crime, quality healthcare, overall cost ...


Fare Policy And Vertical Equity: The Trade-Off Between Affordability And Cost Recovery, Xavier J. Harmony 2018 Northeast Corridor Commission

Fare Policy And Vertical Equity: The Trade-Off Between Affordability And Cost Recovery, Xavier J. Harmony

Journal of Public Transportation

Vertical equity and the maximization of farebox revenue are important but conflicting goals in the development of fare policy in the United States. Reducing fares for low-income riders reduces revenue for a transit agency, while increasing fares could disproportionately impact lower-income riders. This paper details this conflict, explores strategies that could account for both goals, and evaluates fare programs in the United States. Two types of low-income strategies are discussed: first generation strategies and targeted subsidy strategies. First generation strategies have several limitations that targeted subsidy strategies account for; first generation strategies focus more on supply, while targeted subsidy strategies ...


Immigration, Income, And Public Transit Perceptions: Findings From An Intercept Survey, Jesus M. Barajas, Asha Weinstein Agrawal, Daniel G. Chatman 2018 University of Illinois at Urbana-Champaign

Immigration, Income, And Public Transit Perceptions: Findings From An Intercept Survey, Jesus M. Barajas, Asha Weinstein Agrawal, Daniel G. Chatman

Journal of Public Transportation

Although a significant fraction of public transit riders in the United States are immigrants, relatively little research explores whether immigrants have unique transit experiences. This paper analyzes intercept survey data from 1,247 transit riders in the San Francisco Bay Area to explore how mode choices and travel experiences differ for low-income immigrants compared to higher-income immigrants and US-born residents. We find that some public transit experiences are similar across all immigrant status and income groups, while in other ways low-income immigrants differ from their higher-income counterparts or from US-born respondents. In particular, low-income immigrants were less likely to have ...
