This thesis contains an introduction, a literature review, an overview of the study area and data, a description of the methods, results, and discussion and conclusion section. This thesis is significant because it has been the first study to consider cyclist volume as an explanatory variable of the spatiality of car-cyclist dependence for Louisville, Kentucky. Through descriptive and spatial statistics, trends in car-cyclists were identified. Collisions occur more frequently in the summer, during commute hours, …

The Changing Role Of Public-Private Partnerships In Urban Transportation: A Case Study Of The Rise Of P3s In Denver, Co, Sylvia Arriaga Brady

Electronic Theses and Dissertations

This research examines the expanding role of public-private partnerships (PPPs or P3s) in Denver metro transportation projects in three areas: (1) innovative funding and financing of transit infrastructure projects, (2) the partnerships between freight and passenger rail services, and (3) emerging collaborations of local governments, transit agencies, and transportation network companies (TNCs).

The purpose of the first study was to examine the recent use of P3s in the Denver Regional Transportation District's (RTD) FasTracks program, a 2004 voter-approved $4.7 billion transit expansion program. After a shortfall in funding, RTD partnered with several private consortia to enable the FasTracks program to …

Rail Rebound: The Impact Of Freight Rails On Regional Development In The United States, 1970-2010, Bishal Bhakta Kasu

Electronic Theses and Dissertations

Railroads have played a critical role in economic growth and development, and they exert a tremendous impact on the distribution and redistribution of the population. However, the impacts of railroads, especially freight rails, on population change and socioeconomic development are not well understood. This study fills the gap in the literature by examining the demographic and socioeconomic impacts of freight rails using county-level data in the continental United States from 1970 to 2010. The demographic and socioeconomic changes are measured by eleven dependent variables. Of those eleven, six are demographic (population, young, old, White, Black, Hispanic) and five are socioeconomic …

The Roles Of Perceived Subjective Norms And Anticipated Sexism In Women's Intentions To Pursue A Career In Transportation, Elizabeth Colbert Johnson

Electronic Theses and Dissertations

The intention of this study was to better understand the significant underrepresentation of women in the transportation industry. The present study examined the relationships between female high school students' anticipation of a sexist workplace climate in transportation workplaces, perceived subjective norms about transportation work, and intentions to pursue a career in the transportation industry, using the Theory of Reasoned Action (TRA). A sample (N = 132) of female high school students completed measures of anticipated sexism in transportation careers, perceived subjective norms, and transportation career intentions. Results of a regression analysis indicated that higher perceived subjective norms were a …

Economic And Traffic Impacts Following The Installation Of New Bicycle Facilities: A Denver Case Study, Stephen Antonio Rijo

Electronic Theses and Dissertations

America is currently experiencing a unique departure from the historical vehicle miles traveled (VMT) trend, often referred to as "peak travel." Decreasing VMT numbers suggest that the US is currently experiencing an unprecedented change in the way individuals utilize transportation systems. The following research calls on a need to understand the importance of improving alternative transportation infrastructure, namely cycling facilities, and how this impacts local businesses and their communities. This research informs the overarching question, "What are the economic and traffic impacts of cycling facilities?" A mixed methods analysis of retail sales tax, traffic count, and RTD transit access data …

Mobility And Aging In Denver, Colorado: Travel Behavior, Mobility Barriers, And Perceptions Of Transit, Sylvia Arriaga Brady

The Perceived Effectiveness Of Container Security At Seaports Along The Gulf Coast, William Augustus Neely

Electronic Theses and Dissertations

With approximately 90% of the world's goods shipped via cargo containers, it is vital for the security of these containers to be complete and effective. However, given the volume of containers transiting U.S. seaports, the task of providing complete security is complicated and, arguably, impossible. Nevertheless, the data analyzed throughout this study indicates that the current container security paradigm can be enhanced to accommodate the significant workload. The research conducted throughout this study provided perceptions that were indicative of a security environment that can be and must be improved. More specifically, the data revealed that the biggest threat facing containers …

Alternative Methods Of Eliciting Individual Willingness To Pay For Travel Time Savings: A Pilot Study, Ashley Lascelles

Electronic Theses and Dissertations

How does one estimate the value of an individual's time? One possible way is to estimate how much a person is willing to pay for time savings. The majority of transportation studies have used stated preference surveys to estimate an individual's willingness to pay (WTP) for travel time savings. However, stated preferences approaches are subject to hypothetical bias since they elicit WTP for hypothetical outcomes instead of real outcomes. One study used a revealed preference approach in a natural experiment to elicit WTP for travel time savings but the data was for a non-recurring event, which was not replicable. The …

Public Participation In Transportation: An Emperical Test For Authentic Participation, Jorge Cesar Figueredo

Electronic Theses and Dissertations

This dissertation examines the public participation activities of State Departments of Transportation (SDOTs) in the United States. A review of existing literature and legal frameworks suggests that an "authentic" public participation results when dimensions of representativeness, use of public inputs, interactiveness, and quality of citizen inputs have been achieved. The study sought to identify conditions that serve as measurements that must presumably be satisfied for authenticity to exist in public participation. The result was a Model of Authentic Public Participation that served as the basis for creation of a new four-tiered methodology to assess the performance of these districts relative …
