DOT staff and technology resources have the proven potential to help combat human trafficking if DOT employees know the indicators of human trafficking and how to cooperate with requests from agencies for information that can be derived from DOT assets. The Texas A&M Transportation Institute, NCHRP, and the Heart of Texas Human Trafficking Coalition will discuss the intersection of human trafficking with the transportation sector. Attendees will also learn the main components of human trafficking, the basic signs of human trafficking on DOT facilities, and resources to use in their own states.

Uncertainty Quantification And Fragility Development Of Deteriorating Rc Bridge Piers,
2023
Portland State University
Uncertainty Quantification And Fragility Development Of Deteriorating Rc Bridge Piers, Ayush Bhandari
Dissertations and Theses
Corrosion can reduce structural capacity and increase the risk of bridge damage/failure under extreme events. The impact of corrosion on seismic fragility of bridges has been well studied. However, the methodology used in most existing studies requires detailed information on the structural design and condition of a bridge, which is a major hindrance in conducting seismic risk assessment for a large population of bridges. Furthermore, existing studies do not adequately address the time-dependency of uncertainties associated with fragility curve development. This study presents a methodology to generate time-dependent seismic fragility curves for deteriorating highway bridges based only on the limited …

The Influence Of Corrosion Mitigating Fluids On Post Tensioned Tendon Grout Properties And Steel To Grout Bond Strength, Sarita Ale Magar
USF Tampa Graduate Theses and Dissertations
Corrosion has been a persistent problem causing the failure of post-tensioned tendons in segmentally constructed bridges. To address this issue, the impregnation method has been considered where the corrosion-mitigating fluids are pressure injected into the interstitial spaces between the seven wires of steel strands. A previous study showed that this method was able to arrest corrosion. However, it compromised the bond strength between the steel and the strand. For that reason, this study aims to identify a fluid that can be impregnated into the interstitial spaces without sacrificing bond performance. The most promising fluid found in the study is an …

The Influence Of Bipolar Electrochemical Cell Geometry On The Studies Of Pitting Corrosion, Amin Kazem Ghamsari
USF Tampa Graduate Theses and Dissertations
Bipolar electrochemistry (BPE) is a technique that provides a wireless alternative totraditional electrochemistry to elicit redox reactions. It has been utilized in different applications, including studying localized corrosion, gradient electrodeposition, propulsion of micromotors, and water treatment. The popularity of the method is not solely dependent on its wirelessness but more due to the simultaneous presence of cathodic and anodic poles on the same surface, which also begets its name as bipolar. The concept of the method is based on the polarization of conductive objects in an electric field in the presence of an electrolyte. In BPE, instead of controlling the …

Matrix Laboratory (MATLAB) software have been used to program the methodology. This methodology has been applied to Karbala using actual data. …
Rehabilitation Technologies To Abate Infiltration In Sanitary Sewers,

University of South Florida
Rehabilitation Technologies To Abate Infiltration In Sanitary Sewers, Steve Youssef
USF Tampa Graduate Theses and Dissertations
In urban coastal environments, sewer infrastructure is plagued by infiltration which seeps into aging and compromised pipes. Infiltration increases pumping costs, reduces treatment efficiency, and may trigger release of partially treated wastewater at water reclamation facilities. To restore pipes and abate infiltration, local utilities rely on structural and non-structural trenchless rehabilitation technologies. These methods are commonly used throughout the United States and the world due to their numerous benefits compared to traditional open-cut construction. However, limited data is available regarding their efficacy in reducing infiltration in sewer systems. In this study, we analysed infiltration in a small urban sewershed in …
Application Of Connected Vehicle Data To Assess Safety On Roadways,

Boise State University
Application Of Connected Vehicle Data To Assess Safety On Roadways, Mandar Khanal, Nathaniel Edelmann
Civil Engineering Faculty Publications and Presentations
Using surrogate safety measures is a common method to assess safety on roadways. Surrogate safety measures allow for proactive safety analysis; the analysis is performed prior to crashes occurring. This allows for safety improvements to be implemented proactively to prevent crashes and the associated injuries and property damage. Existing surrogate safety measures primarily rely on data generated by microsimulations, but the advent of connected vehicles has allowed for the incorporation of data from actual cars into safety analysis with surrogate safety measures. In this study, commercially available connected vehicle data are used to develop crash prediction models for crashes at …

Electrical and Computer Engineering Faculty Research & Creative Works
Fly ash (FA) – an industrial byproduct – is used to partially substitute Portland cement (PC) in concrete to mitigate concrete's environmental impact. Chemical composition and structure of FAs significantly impact hydration kinetics and compressive strength of concrete. Due to the substantial diversity in these physicochemical attributes of FAs, it has been challenging to develop a generic theoretical framework – and, therefore, theory-Based analytical models – that could produce reliable, a priori predictions of properties of [PC + FA] binders. in recent years, machine learning (ML) – which is purely data-driven, as opposed to being derived from theorical underpinnings – …
Modeling Vehicle-Miles Of Travel Accounting For Latent Heterogeneity,

Modeling Vehicle-Miles Of Travel Accounting For Latent Heterogeneity, Fatemeh Nazari, Abolfazl (Kouros) Mohammadian
Civil Engineering Faculty Publications
Vehicle use is associated with negative externalities such as traffic congestion, air pollution, and greenhouse gas emissions. Particularly in the U.S. as a car-oriented country, vehicle use — in terms of vehicle-miles of travel (VMT) — has been on the rise and is projected to increase in the future. To curb the VMT growth and mitigate the associated externalities, policy makers can design informed strategies based on VMT predicted by vehicle use models. However, traditional vehicle use models capture merely the observed heterogeneity across vehicle decision making units (e.g., individuals) and ignore the latent or taste heterogeneity sourced in …

Civilian And Military Civil Engineer Mission In The Space Domain, Linda E. Kuster
Theses and Dissertations
Military and civil interest in space-based operations has increased dramatically in recent years due to the discovery of life sustaining properties such as water on Mars and advancements in cyber technology. Civilian sector discussions and research have centered on the establishment of permanent extraterrestrial infrastructure, while discussions from the military perspective have focused on providing reliable, resilient infrastructure, capable of withstanding cyber-based and kinetic attacks. Both perspectives account for known threats and sustainment methods required to ensure success in the space domain. With the existence of threats for the military and civilian missions, civil engineers will undoubtedly be critical to …

Mineta Transportation Institute
The California Freight Mobility Plan 2020 lists the Los Angeles-Inland Empire trade corridor region as a prominent industrial hub experiencing an increase in freight flows. The California Freight Mobility Plan also regards automated truck platoon (ATP) as an emerging opportunity to minimize congestion on the trade corridor routes. Percentage change in accessibility from 2022 (“without” ATP) to 2040 (“with” ATP) is calculated for the eighteen industry sectors of the Los Angeles-Inland Empire trade corridor. The application of the accessibility formulation was carried out with data on travel time from I-710 and I-10 within Los Angeles County. The findings suggest that …
