New Framework And Decision Support Tool To Warrant Detour Operations During Freeway Corridor Incident Management, Jing Mao
Theses and Dissertations
As reported in the literature, the mobility and reliability of the highway systems in the United States have been significantly undermined by traffic delays on freeway corridors due to non-recurrent traffic congestion. Many of those delays are caused by the reduced capacity and overwhelming demand on critical metropolitan corridors coupled with long incident durations. In most scenarios, if proper detour strategies could be implemented in time, motorists could circumvent the congested segments by detouring through parallel arterials, which will significantly improve the mobility of all vehicles in the corridor system. Nevertheless, prior to implementation of any detour strategy, traffic managers …

Demand Responsive Signal Control Strategy (Drsc) Incorporating Queue Length Information In Real-Time Signal Control, Rahul Rajbhara
Civil & Environmental Engineering Theses & Dissertations
Most of the existing vehicle detection systems, namely inductive loops, video cameras etc. are incapable of measuring the queue lengths at signalized intersections. However, with the advent of modern technology, newer detection methods such as probe vehicles equipped with wireless communications (Connected Vehicles), particularly under the Vehicle Infrastructure Integration [52), and radar detection currently provide this capability [53). This thesis presents a Demand Responsive Signal Control Strategy (termed as DRSC) for an isolated signalized intersection. The control strategy incorporates real-time queue length information (obtained from probe vehicles) into the signal control logic. Demand based maximum green time for each upcoming/new …

Towards Managing And Understanding The Risk Of Underwater Terrorism, Richard J. Gay
Towards Managing And Understanding The Risk Of Underwater Terrorism, Richard J. Gay
Engineering Management & Systems Engineering Theses & Dissertations
This dissertation proposes a methodology to manage and understand the risk of underwater terrorism to critical infrastructures utilizing the parameters of the risk equation. Current methods frequently rely on statistical methods, which suffer from a lack of appropriate historical data to produce distributions and do not integrate epistemic uncertainty. Other methods rely on locating subject matter experts who can provide judgment and then undertaking an associated validation of these judgments.
Using experimentation, data from unclassified successful, or near successful, underwater attacks are analyzed and instantiated as a network graph with the key characteristics of the risk of terrorism represented as …
The Effects Of Familiarity And Persuasion On Risk Assessment, Casey L. Smith
The Effects Of Familiarity And Persuasion On Risk Assessment, Casey L. Smith
Doctoral Dissertations and Master's Theses
Cognitive biases influence decisions and the analyses of risk. They are often derived from two separate processes: bias based on familiarity (familiarity bias) and bias as the result of influences from outside sources (persuasion bias). Research suggests that familiarity-based bias may lead to acceptance of an activity's drawbacks and a leniency of its risks.
In addition, research has tried to measure and analyze different types of biases individually, but few have compared the interactions of more than one bias at once. Because different biases may derive from different mental phenomena it is important to tease out the distinctions, and observe …
The Effects Of Expertise And Information Location On Change Blindness Detection Within An Aviation Domain, Dinorah Zárate
The Effects Of Expertise And Information Location On Change Blindness Detection Within An Aviation Domain, Dinorah Zárate
Doctoral Dissertations and Master's Theses
Change blindness is a phenomenon where the viewer fails to detect change in an object or scene during a visual disturbance. During a flight, a pilot samples multiple displays for information about the task at hand. It is imperative that the changes in the displays are being correctly viewed by pilots to ensure a safe flight. However, it is unknown how much change blindness affects pilots or if pilot expertise plays a role in change detection.
A change blindness experiment was performed with twenty four participants divided into two groups based on expertise. Expert pilots were defined as instructor pilots …
The Effect Of Control And Display Lag On Uas Internal Pilot Manual Landing Performance, Marshall Everett Lloyd
The Effect Of Control And Display Lag On Uas Internal Pilot Manual Landing Performance, Marshall Everett Lloyd
Doctoral Dissertations and Master's Theses
An important characteristic of UASs is lag because it can become a considerable challenge to successful human-in-the-loop control. As such, UASs are designed and configured to minimize system lag, though this can increase acquisition and operation costs considerably. In an effort to cut costs, an organization may choose to accept greater risk and deploy a UAS with high system lag. Before this risk can be responsibly accepted, it must be quantified.
While many studies have examined system lag, very few have been able to quantify the risk that various levels of lag pose to an internally piloted, manually landed UAS. …

Using Geographic Information Systems To Analyze Accessibility In The West Bank, Jacob Elliott
All Theses
With the recent failure of another highly publicized peace talks, the Israeli-Palestinian conflict remains a polarizing and contentious geopolitical crisis. Following the Israeli victory in the Six Day War of 1967, the West Bank and its substantial Palestinian population have lived under Israeli occupation. In response to the First Palestinian Intifada (uprising), lasting from1987 to 1993, the Israeli military imposed varying degrees of regulations to limit Palestinian mobility within the West Bank. The mobility constraints, most notably in the form of checkpoints, roadblocks, and physical obstructions, dramatically increased in volume and scale during the Second Intifada from 2000 to 2005. …

Modeling Travel Time And Reliability On Urban Arterials For Recurrent Conditions, Prony Bonnaire Fils
USF Tampa Graduate Theses and Dissertations
Abstract
Travel time reliability is defined as the consistency or dependability in travel times during a specified period of time under stated conditions, and it can be used for evaluating the performance of traffic networks based on LOS (Level of Service) of the HCM (Highway Capacity Manual). Travel time reliability is also one of the most understood measures for road users to perceive the current traffic conditions, and help them make smart decisions on route choices, and hence avoid unnecessary delays (Liu & Ma, 2009). Therefore, travel time reliability on urban arterials has become a major concern for daily commuters, …
