Safety performance of curve advisory speed signs

Creator:: Avelar Moran, Raúl Eduardo
Abstract:: Posting advisory speed signs at sharp horizontal curve sites is a practice well established in the United States. The purpose of these signs is to provide the driving public with a safe speed to negotiate such curves; however, the link between these signs and safety has not yet been clearly...

Utilizing wireless-based data collection units for automated vehicle movement data collection

Creator:: Saeedi, Amirali
Abstract:: There are many different types of automatic data collection technologies that have been used in transportation system applications such as pneumatic tubes, radar, video cameras, inductive loops detectors, wireless toll tags, and global positioning systems (GPS). Nevertheless, there are still multiple examples of important and helpful transportation system data that...

Knowing Concepts in the Social and Material Context of Engineering Practice

Creator:: Bornasal, Floraliza
Abstract:: It is expected that information taught in the context of school will ultimately transfer to workplace settings. To support this transition, educators and researchers advocate for organizing foundational ideas, or concepts, in specific domains of knowing. In the domain of transportation engineering, knowing of concepts, which include "big ideas" such...

Interactive Genetic Algorithms for watershed planning : an investigation of usability and human-centered design

Creator:: Piemonti, Adriana Debora
Abstract:: Degradation of watersheds is a major concern in areas where adverse climate effects and unsustainable use of the natural resources have caused extensive stresses to watershed systems (e.g., increased floods, increased droughts, worsened in-stream water quality) through the years. While considerable efforts are being made to generate technical solutions that...

Human Error in Helicopter Accidents : Understanding the Manifestation of Human Error across Helicopter Missions

Creator:: Morowsky, Katarina A.
Abstract:: Human error is responsible for the majority of accidents in complex environments including helicopter operations. To reduce the overall accident rate throughout the helicopter industry, we must first understand how helicopter missions differ from one another and what errors lead to accidents. The research documented in this dissertation involved a...

Quantifying the Safety and Mobility Benefits of Connected Vehicle Technologies under Varying Levels of Market Penetration and Traffic Volume : An Agent-Based Modeling Framework

Creator:: Abdulsattar, Harith M.
Abstract:: The advancement of the cutting-edge technologies of advanced driver assistance systems (ADAS) hold promises to reshape the future of the transportation system. The concept of connected (CV) and connected automated vehicles (CAV) technologies are live examples of the future transportation. Vehicle communication technology is expected to impact conventional traffic conditions....

Modeling Unobserved Heterogeneity and the Injury Severities of Truck Drivers in Run-Off-Road (ROR) Crashes: Econometric Methods and Applications

Creator:: Al-Bdairi, Nabeel Saleem Saad
Abstract:: Recent statistics regarding large truck crashes reveal that fatality rates of large trucks per 100 million vehicle miles traveled (VMT) and fatality rates per 1,000 registered vehicles are higher than those for passenger vehicles. These statistics underscore the need for greater efforts by safety professionals to help mitigate the impacts...

Unobserved Heterogeneity and Spatial Correlation: Statistical and Econometric Analyses of Heavy-Vehicle Hard Braking and Crash Frequency by Crash Type

Creator:: Anderson, Jason C.
Abstract:: This dissertation provides a comparison of statistical and econometric frameworks, using a previously unused freight data source, to study crash frequency by crash type and heavy-vehicle hard braking in Oregon. Hard braking can serve as a proxy for several factors, one of which is safety. Therefore, with the hard braking...

Investigation of In-tube Non-equilibrium Condensation of Low Global Warming Potential Refrigerants

Creator:: Jacob, Tabeel A.
Abstract:: This work investigates the in-tube condensation of low global warming potential (GWP) zeotropic refrigerant mixtures R448A, R450A, R452A, R454B and R454C. These refrigerants have been proposed for a wide range of commercial heating, ventilation, air-conditioning applications, but their heat and momentum transport phenomenon were not well understood. Thus, in this...
