The Economic Implications Of Evolving Aviation Funding Policy In Tennessee, Hunter Pressley Mccracken

Masters Theses

The majority of state funding for capital improvements at Tennessee’s general aviation and commercial airports comes through grants awarded from the Tennessee Transportation Equity Trust Fund (TETF). Through a 4.5 percent sales and use tax on the consumption of aviation fuel, users help to fund the continued improvement and maintenance of aviation facilities around the state. Aircraft refueling operations associated with the FedEx “SuperHub” in Memphis were responsible for two-thirds of the TETF’s revenue for Fiscal Year 2014. In response to speculation that FedEx would relocate its refueling operations to reduce its fuel tax liability, the Tennessee General Assembly passed …

The Economics Of Crime, Bryan S. Weber

Theses and Dissertations

Essay 1: “Can Safe Ride Program Reduce Urban Crime?” This paper evaluates the influence of a safe ride program at a public university on neighborhood crime in a major urban area. Using an hours of the week panel, the program's operation is associated with an approximate 14 percent reduction in crime. The program being open appears to have roughly similar influence in reducing violent and non-violent crime. Moreover, increases in rides (the intensity of the program) are also associated with reductions in crime. Such increases in program intensity are also associated with notably greater reductions in crime occurring on weekends. …

Work Zone Illumination Design: Guidance Stratgies To Specify Appropriatework Zone Lighting Plan, Sherine Anani

Theses and Dissertations

Night construction is frequently used because it can better satisfy the primary traffic control objectives than daytime work. If night construction is used, the design of illumination plans should be analyzed and developed as part of the project development process.

There are fewer crews out working on the road in the winter, partly because of the conditions but also because the days are shorter and there’s not a lot of light by which to work.

In fact, the days can get short enough, especially as you go farther north, that even a normal day involves some “night work.” Construction work …

Locational Advantage And The Impact Of Scale: Comparing Local And Conventional Fruit And Vegetable Transportation Efficiencies, Charles Cate Grigsby

Masters Theses

Fresh produce in the United States often travels thousands of miles in diesel operated semi-trucks before arriving to market. Under a high fuel cost scenario, the current low-cost, efficient supply chain could become a high cost organizational structure for US food distribution. Rising transportation costs of food sourced from distant locations may provide competitive opportunities for small- and mid-sized local producers if transportation costs are a smaller portion of their total costs. Farmers selling fresh produce in east Tennessee farmer markets are surveyed to obtain baseline information on their transportation energy use to deliver their products to market. Local farmer …

Determining The Degree Of Collaboration Readiness For Regional Transportation Systems: The Formulation Of A Model, Carol Farver

Master's Theses and Doctoral Dissertations

The purpose of this study was to identify factors, both governmental and universal, that indicate the degree of readiness and/or potential for success of a government collaborative project in the field of regional rapid mass transportation. The study is important because collaboration has been recognized as a tool that can help address such challenges as demonstrating the responsible use of limited resources, anticipating converging technologies, and reacting to rapidly changing technologies. There was very limited availability of tools to assist in ensuring successful collaborations. Although tools have been developed that gauge the degree of collaborative readiness of a project, such …

Teenagers' Mode Choice To And From School And Technology Use For Transportation: Analysis Of Students From Five High Schools In Vermont And California, Paola Rekalde Aizpuru

Graduate College Dissertations and Theses

The carhops and drive-ins of the 1950s are symbolic of the freedom that the automobile has granted Americans. What the general public has gained from the automobile, however, may come at the expense of independent mobility and choices for today's adolescents, particularly those not yet old enough to drive or those from lower income families. Sprawl land use development patterns and limited transportation choices in most American cities often hold teenagers and their chauffeuring parents captive to the automobile. At the same time, information and communication technology is fast evolving and changing the ways in which teenagers live, interact, and …

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

Electronic Theses and Dissertations

The purpose of this case study was to explore issues that can inhibit efficiency of security agency operation and collaboration and to identify actions that have enhanced collaboration. Based on theories of organizational development, leadership, and security tradecraft, this study examined the activities related to maintenance of security at a large California …

The Economic Impact Of Transportation Network Companies On The Taxi Industry, Alice Wang

Scripps Senior Theses

Transportation Network Companies (TNC) are companies that use online-enabled platforms to connect passengers with drivers. In recent years, they have sparked controversy with the taxi industry, which accuses TNCs of operating unfairly. In my study, I look at taxi regulation, consumer transportation preferences, and costs and benefits of TNCs. I analyze data comparing three of these companies, Uber, Lyft, and Sidecar, with a traditional taxicab, and evaluate trends in taxi employment from the Bureau of Labor Statistics. I find that Transportation Network Companies generally have shorter wait times, cheaper prices, and increased convenience, aspects that appeal to consumer preferences. I …

Business Strategies To Improve On-Time Deliveries And Profits In Southcentral Alaska, Donald Richard Leaver Ii
