Analysis And Evaluation Of Safety Impacts Of Median Types And Midblock Left Turn Treatments For Urban Arterials, Timur Mauga
Analysis And Evaluation Of Safety Impacts Of Median Types And Midblock Left Turn Treatments For Urban Arterials, Timur Mauga
UNLV Theses, Dissertations, Professional Papers, and Capstones
Urban growth leads to new land-uses abutting arterials requiring driveways for their accessibility. Uncontrolled number and locations of such access points causes safety, mobility and accessibility problems. The solution to these problems is access management (AM) which controls the number and location of the access points. AM techniques are normally documented in the form of guidelines for engineers and planners to follow when implementing the techniques. However, AM guidelines may not cover every technique due to the fact that AM is still growing. For example, the current AM guideline prepared by The Nevada Department of Transportation addresses many AM techniques. …
Lean Manufacturing As A Source Of Competitive Advantage, Ryan Scott Williams
Lean Manufacturing As A Source Of Competitive Advantage, Ryan Scott Williams
Theses and Dissertations
The productivity advances generated from lean manufacturing are self-evident. Plants that adopt lean are more capable of achieving high levels of quality, shorter lead times, and less waste in the system. While it seems logical that higher levels of productivity and quality, as is common in lean companies, should result in positive financial performance, the research community has failed to establish the financial profitability of lean. Those researchers who have studied the financial returns issue report varying results. The goal of this research was to determine if a connection exists between lean and financial success and to discover why so …

Redesigning Airport Diagrams With Principles Of Cognitive Psychology, Jacob Miller
Redesigning Airport Diagrams With Principles Of Cognitive Psychology, Jacob Miller
Master's Theses - Daytona Beach
The aviation community strives for air travel to be the safest form of transportation. The National Transportation Safety Board published a “Most Wanted” list to acknowledge the most threatening safety issues, and runway safety and runway incursions were at the top of their list. Furthermore, runway incursion statistics by the Federal Aviation Administration show that pilot deviations were the most common cause for runways incursions. Misunderstandings of airport diagrams may be one reason for pilot deviations. While navigating through airport taxiways, pilots refer to their airport diagrams as a map of the airport. Unfortunately, airport diagrams are not designed with …
A Predictive Game Theoretic Model To Assess Us - Russian Response To An Islamic Safe-Haven In The Caucasus Region, Christopher Wayne Hartline
A Predictive Game Theoretic Model To Assess Us - Russian Response To An Islamic Safe-Haven In The Caucasus Region, Christopher Wayne Hartline
Computational Modeling & Simulation Engineering Theses & Dissertations
The thesis examines possible US and Russian policy decisions following the establishment of an Islamist safe-haven in Chechnya. Conflicting national policies affect the possibility of a negotiated settlement. Domestic and international political considerations constrain the decision-making of the two nations. The author applies game theory to examine the sequential decision-making of the two nations. The extensive form model draws outcome payoff values from a bounded uniform distribution. This approach naturally models uncertainty; and, it allows repeated probabilistic instantiations of the model. These instantiations produce a range of solutions. The most likely outcome was a negotiated settlement, generally following a tit-for-tat …

Statistical Modeling And Analysis Of Injury Severity Sustained By Occupants Of Passenger Vehicles Involved In Crashes With Large Trucks, Ahmad Koupaenejad
UNLV Theses, Dissertations, Professional Papers, and Capstones
Crashes are the result of complex interactions between several factors representing driver, roadway, vehicle, and environmental characteristics. Understanding to what degree each factor contributes to the severity of a crash is not a simple task. The outcomes of crashes in the US have been an average of 42,000 deaths and 3 million injuries per year. To better understand the role of significant contributors to crashes, three sets of models using multinomial logit and one using ordered probit were calibrated. To calibrate these models, forty two independent predictor variables including driver/occupants characteristics, crash environment at the crash location, crash characteristics, and …
Evaluation Of Safety Impact Of Access Management In Urban Areas, Xuecai Xu
Evaluation Of Safety Impact Of Access Management In Urban Areas, Xuecai Xu
UNLV Theses, Dissertations, Professional Papers, and Capstones
The access provided by streets and highways to adjacent lands are managed by controlling the spacings between the access points including signals, driveways, and media openings on mid-block segments, and setting the limit on the corner clearances around intersections. There have been studies on evaluating the impact of access management techniques on safety and mobility in urban areas. Samples of mid-block segments and intersections can be collected from selected arterials. Because the mid-block segments or intersections in the same arterials share the same missing information, safety and mobility on them show unique features that should be taken into account when …
