Assessment Of Parameters For A Safe And Equitable Roadway Network For Pedestrians Of South Carolina, Sababa Islam
Assessment Of Parameters For A Safe And Equitable Roadway Network For Pedestrians Of South Carolina, Sababa Islam
All Dissertations
In 2019, South Carolina ranked fourth in the nation in pedestrian fatalities per 100,000 population. There has been a 68% increase in total pedestrian crashes in SC from 2011 to 2018. Walking might be a choice for some individuals; however, it is mandatory for some users due to the unavailability of personal automobiles or physical disability. Thus, pedestrian crashes and resulting deaths and injuries can disproportionately affect these population segments. Nationwide pedestrian crash statistics reveal American Indian or Alaskan Native and African American populations are overburdened with pedestrian crashes. This research aims to help mitigate this overburden of pedestrian crashes …

The research team conducted a literature review and a nation-wide survey at the beginning of the research. The literature review revealed that Adaptive Signal Control System (ASCS) was effective in reducing crashes in some studies, while in other studies, the crash reduction due to ASCS was not statistically significant. Twenty-eight states participated in the nation-wide survey and helped the research team identify corridor characteristics, such as the design speed and Annual Average Daily Traffic (AADT) of an ASCS corridor, which would allow for the best operational and safety outcomes. Then, to determine the safety effects of ASCS, the research team …

Benefits Of A State Driveway Database With Qualitative And Quantitative Crash Analysis, Andrew Bryant Stokes
Benefits Of A State Driveway Database With Qualitative And Quantitative Crash Analysis, Andrew Bryant Stokes
All Theses
The primary goal of this research is to show how a fully developed driveway database will improve access management practices resulting in a reduction in crashes, injuries, and fatalities on our roadways. The results of this thesis highlight a close relationship between driveway characteristics and the incidence of crashes. Thus, it is critical to be proactive in enforcing access management strategies and policies that are designed to enhance driveway safety without compromising the economic vitality of land use along roads. The analysis identified several significant independent variables that influence crash rates either positively or negatively. The data driven approach to …
Thermally Responsive Polymer Electrolytes For Inherently Safe Electrochemical Energy Storage, Jesse Kelly
Thermally Responsive Polymer Electrolytes For Inherently Safe Electrochemical Energy Storage, Jesse Kelly
All Dissertations
Electrochemical double layer capacitors (EDLCs), supercapacitors and Li-ion batteries have emerged as premier candidates to meet the rising demands in energy storage; however, such systems are limited by thermal hazards, thermal runaway, fires and explosions, all of which become increasingly more dangerous in large-format devices. To prevent such scenarios, thermally-responsive polymer electrolytes (RPEs) that alter properties in electrochemical energy storage devices were designed and tested. These RPEs will be used to limit or halt device operation when temperatures increase beyond a predetermined threshold, therefore limiting further heating. The development of these responsive systems will offer an inherent safety mechanism in …
The Feasibility Of Using An Instrumented Vehicle Equipped With Inertial Navigation Guidence System To Collect Roadway Grade And Cross-Slope Data For Safety Analysis, Cyle Rhoades
All Theses
In 2005, the Federal Highway Administration (FHWA) requested the development for the initial version of the Model Minimum Inventory of Roadway Elements (MIRE). MIRE is a roadway inventory and traffic data collection data program that has a strong focus on improving the decision process in safety programs. MIRE is not a mandatory state program, but is strongly recommended based on its potential advantages. Some of the data required for MIRE was previously collected as a result of the requirements set from the Highway Performance Monitoring System (HPMS).
This thesis concentrates on the feasibility of determining as-built grade and cross-slope data …
Human Error In Mining: A Multivariable Analysis Of Mining Accidents/Incidents In Queensland, Australia And The United States Of America Using The Human Factors Analysis And Classification System Framework, Jessica Patterson
All Dissertations
Historically, mining has been viewed as an inherently high-risk industry. Nevertheless, the introduction of new technology and a heightened concern for safety has yielded marked reductions in accident and injury rates over the last several decades. In an effort to further reduce these rates, the human factors associated with incidents/accidents need to be addressed. A modified version of the Human Factors Classification and Analysis System (HFCAS-MI) was used to analyze lost time accidents and high-potential incidents from across Queensland, Australia and fatal accidents from the United States of America (USA) to identify human factor trends and system deficiencies within mining. …
