World Maritime University Ph.D. Dissertations

In the maritime industry, a significant number of emerging and complex challenges occurring, has engaged limited attention and tenuous governance structures that can hardly deal with such complexities. Hence, the need for practitioners to seek innovative planning approaches for addressing such complexities, particularly the cumulative impacts on the marine environment. Such swelling effect, cannot be overemphasized in the Gulf of Guinea marine region which lies between Cape Lopez in Gabon and Cape Palmas in Liberia. This region, has a long history of conflicting marine uses and unresolved disputes. Prior to 2020, three adjacent nations in this region have engaged in …

Open Access Theses & Dissertations

Improving the durability and long-term performance of the asphalt concrete (AC) has become a major concern, especially with the increase in the use of recycled materials, warm mix asphalt additives and modified binders. To balance the mechanical properties durability and stability of AC mixtures, mix design approaches that incorporate performance tests are needed. This Thesis presents an experimental evaluation of different mix design approaches to balance the mechanical properties of AC mixtures. The current volumetric-based design method was enhanced with performance-based analysis that specifies parameters from the overlay tester, Hamburg wheel tracking device and indirect tension tests. Four typical Superpave …

More Than A Century After Problem Emerged, Manhole Explosions Still Injuring Dozens In New York City, Gaspard Le Dem, Gabriel Sandoval

Capstones

Since the early days of electrification, New York City has been rattled by manhole explosions –– underground blasts that injure residents, damage buildings, force evacuations, cause power outages and traffic disruptions.

Consolidated Edison, the city's largest electric provider, has for decades blamed manhole issues on bad weather and road salt that erodes underground wires. But some experts and former utility workers say lack of maintenance is at the root of the problem.

Meanwhile, city and state officials have failed to rein in the problem through weak laws and loose oversight. As a result, unsuspecting drivers and pedestrians continue to be …

Sizing A New Bike Sharing System For The University Of Nevada, Las Vegas, Nesley Orochena

UNLV Theses, Dissertations, Professional Papers, and Capstones

The strategic planning objectives for a novel Bike Sharing Systems (BSS) are to locate the BSS stations, size the stations, and determine the bicycle fleet size, among others. Current guidelines to design BSS programs are tailored to city centers with large coverage areas and high bicycle to population ratios, and thus not directly transferable to a university setting. An ordered probit model was created using data from a university online stated preference survey to determine the key factors that affect the uptake rates for the UNLV BSS program and to estimate the potential demand. The demand analysis was incorporated into …

Beyond The Elevators: How The New York City Subway System Can Better Serve Blind, Deaf And Cognitively Disabled People, Ethan B. Stark-Miller

Capstones

Many blind and visually impaired, deaf and cognitively disabled New Yorkers face challenges when using the subway. A large portion of the system is still missing key accessibility features that would make the subway usable for these groups. And while this problem is on the Metropolitan Transportation Authority’s (MTA) radar – the MTA has launched a pilot program to address it – the agency still has no clear plan or timeline for quickly expanding these features to the entire system.

Webinar: Letting Bike Riders Catch The Green Wave, Stephen Fickas, Marc Schlossberg

TREC Webinar Series

The "Fast Track" project at the University of Oregon focuses on a mode of transportation that is sometimes left out of vehicle-to-infrastructure, or V2I, conversations: Bicycling. NITC researchers developed an app based on a new technology being integrated into modern cars: GLOSA, or Green Light Optimized Speed Advisory. GLOSA allows motorists to set their speed along corridors to maximize their chances of catching a "green wave" so they won't have to stop at red lights.

This project demonstrates how GLOSA can be used by bicyclists in the same way it is used by motorists, with a test site on a …

Exploring The Transportation And Land Use Impacts Of E-Commerce, Amanda Howell

PSU Transportation Seminars

E-commerce is growing—it is estimated that e-commerce sales now account for more than 10% of total retail sales in the U.S. The continued maturation of the e-commerce market is fueling a significant growth in warehousing, changing the nature of brick-and-mortar retail, and creating a surge in parcel volumes, which means deliveries are up. Way up. The New York Times recently reported that 1.5 million packages are delivered daily in New York City. In order to meet this demand for delivery, businesses are looking for new and creative ways to deliver packages to consumers, including attempting to automate the last mile. …

An Evaluation Of California’S Continuously Appropriated Programs Funded Through Cap-And-Trade, Domingo Candelas

Master's Projects

In 2006, the State of California passed AB 32, the Global Warming Solutions Act. Through this legislation, the state sought to reduce its carbon emissions to 1990 levels by 2020. The California Air Resources Board (CARB) was tasked with doing so and thus instituted the Cap-and-Trade program, a market-based mechanism to reduce emissions. Additionally, legislation has further directed funding on an annual basis for various continuously appropriated programs. This paper will examine the efficacy of those continuously appropriated programs and their legislative intent.

Contextual Guidance At Intersections For Protected Bicycle Lanes, Christopher M. Monsere, Nathan Mcneil, Yi Wang, Rebecca Sanders

TREC Final Reports

Improved bicycle infrastructure has become increasingly common in the United States as cities seek to attract new riders, including the demographics of people who do not feel comfortable riding with motor vehicle traffic. A key tool is separated or protected bicycle lanes, and intersections are critical links in a low-stress network. This report presents an analysis of the perceived level of comfort of current and potential bicyclists from 277 survey respondents who rated 26 first-person video clips of a bicyclist riding through mixing zones, lateral shifts, bend-in, bend-out and protected intersection designs. A total of 7,166 ratings were obtained from …

Key Enhancements To The Wfrc/Mag Four-Step Travel Demand Model, Reid Ewing, Sadegh Sabouri, Keunhyun Park, Torrey Lyons, Guang Tian

TREC Final Reports

In a National Transit Institute course on “Coordinating Land Use and Transportation,” co-taught by Robert Cervero, Uri Avin, and the PI on this project, the analytic tools session began with a hypothetical: assume that all households, jobs, and other trip generators are concentrated in a walkable village rather than segregated by use and spread across a traffic analysis zone in the standard suburban fashion. The instructor then asks: How would the outputs of conventional four-step travel demand models differ between these two future land use scenarios. The answer, to most participants’ surprise, was “Not at all.” Conventional four-step travel demand …

Biking Safely Through The Intersection: Guidance For Protected Bike Lanes, Christopher M. Monsere, Nathan Mcneil

TREC Project Briefs

Protected bike lanes are becoming increasingly common around the United States, yet there is little guidance for how to extend the protected lanes through one of their most dangerous links: the intersection. Lead by Chris Monsere of Portland State University in collaboration with Toole Design Group, the latest report from the National Institute of Transportation and Communities (NITC) offers contextual guidance for designing intersections that are comfortable for cyclists.

New Travel Demand Modeling For Our Evolving Mobility Landscape, Reid Ewing

TREC Project Briefs

Conventional four-step travel demand modeling is overdue for a major update. The latest NITC report from University of Utah offers planners a better predictive accuracy through an improved model, allowing for much greater sensitivity to new variables that affect travel behavior. Specifically, it accounts for varying rates of vehicle ownership, intrazonal travel, and multimodal mode choices. Used by nearly all metropolitan planning organizations (MPOs), state departments of transportation, and local planning agencies in the United States, the importance of travel demand modeling for project selection cannot be overstated: They are the basis for forecasting future travel patterns and developing long-range …
