Transportation Network Resiliency: A Fuzzy Systems Approach, Nayel Urena Serulle
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Every day the dependence on transportation grows as local, regional, national, and international independence increases. Resilient transportation systems are needed to secure the highest possible level of service during disruptive events, including natural and man-made disasters. Because of limited resources, decision makers need guidance on how, when, and where to invest to improve resiliency of their networks. The research objective is to develop a method to assess and quantify resiliency, at pre-event conditions, using a fuzzy inference approach. This research expands previous work, refining key variable definitions, adjusting model interactions, and increasing transparency between metrics. This thesis presents the method …
Safety Evaluation Of Work Zone Practices In Utah, Tomás Ernesto Lindheimer
Safety Evaluation Of Work Zone Practices In Utah, Tomás Ernesto Lindheimer
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Work zones present a risk to drivers and to personnel constructing the roadway. In 2005 work zones accounted for 2.5% of fatalities nationwide, 3.5% for the state of Utah. The goal of this research is to make work zones safer by quantifying the risk that they present to drivers. The approach of this research has been to review part 6 of the Manual of Uniform Traffic Control Devices (MUTCD) and compare the differences from the 2003 and 2009 editions, conduct field studies of Utah work zones, and develop a tool for measuring risk in work zones. In the 2009 MUTCD …
