Understanding And Modeling Drivers’ En-Route Diversion Behavior During Congestion, Mohammad Shapouri
LSU Doctoral Dissertations
In the field of transportation, traffic assignment models primarily have been used to forecast driver route preferences, translating their choices into traffic flow patterns across networks. These models are grounded in distinct behavioral theories and strive to explain how drivers navigate routes based on network features and personal tendencies. Using an aggregation approach, conventional traffic assignment models distribute demand among paths, considering utility and attractiveness. Despite their prevalent use in transportation planning and operations, the fundamental behavioral assumptions of these models have rarely been thoroughly explored. This gap is further compounded by their limited consideration of real-time adjustments and choices …

Integrating The Concept Of Complete Streets Into Pavement Preservation, Sirisha Gangireddy
LSU Master's Theses
This study is motivated by the evident gap in integrating Complete Streets principles into pavement preservation. Complete Streets opportunities, which aim to accommodate all road users, are typically encouraged in all kinds of projects including new construction, reconstruction, preservation, and rehabilitation. While the concept of Complete Streets is understood in terms of new construction (e.g., building sidewalks), its application through pavement preservation programs is not well-developed. To bridge the gap between the Complete Streets and pavement preservation, this study conducted a comprehensive review on how state Department of Transportation (DOTs) are currently incorporating Complete Streets into pavement preservation and identified …

Ai-Based Bridge And Road Inspection Framework Using Drones, Hovannes Kulhandjian
Mineta Transportation Institute Publications
There are over 590,000 bridges dispersed across the roadway network that stretches across the United States alone. Each bridge with a length of 20 feet or greater must be inspected at least once every 24 months, according to the Federal Highway Act (FHWA) of 1968. This research developed an artificial intelligence (AI)-based framework for bridge and road inspection using drones with multiple sensors collecting capabilities. It is not sufficient to conduct inspections of bridges and roads using cameras alone, so the research team utilized an infrared (IR) camera along with a high-resolution optical camera. In many instances, the IR camera …

Research outputs 2022 to 2026
In this research work, we have focused on one of the reasons called drawdown (difference between static and pumping heads) for getting maximum efficiency. Therefore, various mechanical attachments have been designed and fabricated for performance evaluation. Since pump performance and drawdown are inversely related, the primary goal is to reduce drawdown as much as possible. The effect of various types of mechanical attachments on pump performance is investigated in this research work. Three bowl-type mechanical attachments can be integrated at once and can increase efficiency by up to 58%, which is 8% more than utilizing no attachment. Additionally, the impact …

Shoreline cities are influenced by both urban-scale processes and land-water interactions, with consequences on heat exposure and its disparities. Heat exposure studies over these cities have focused on air and skin temperature, even though moisture advection from water bodies can also modulate heat stress. Here, using an ensemble of model simulations covering Chicago, we find that Lake Michigan strongly reduces heat exposure (2.75°C reduction in maximum average air temperature in Chicago) and heat stress (maximum average wet bulb globe temperature reduced by 0.86°C) during the day, while urbanization enhances them at night (2.75 and 1.57°C increases in minimum average air …

Meta-Analysis Of Insulated Concrete Wall Panel Design Methods For Shear And Flexure Behavior, Maryam Al-Bayati
Durham School of Architectural Engineering and Construction: Dissertations, Thesis, and Student Research
Insulated Concrete wall panels have been designed and constructed since the early 1950s with various shear ties, dimensions, and methods; nonetheless, thermal bridging and rational design are still a concern. Many companies have recently developed plastic connectors that have gradually replaced solid concrete sections and steel connectors due to their superior thermal efficiency and strength. However, there is no generally accepted method for predicting the behavior of sandwich wall panels in structural engineering practice or codes, but many methods have been used since the early 1920. This study aims to evaluate the accuracy of current methods for predicting the flexural …

The Effects Of Disruption Type, Trip Purpose, Gender, And Age On Driver Diversion Willingness In The United States Of America, James D. Fuller
LSU Master's Theses
When drivers encounter traffic congestion, one of the most common ways to avoid excessive delays is to divert to an alternate route. Despite the commonplace nature of such routing decisions, relatively little is known about the specific influencers, motivators, and preferences that affect diversion choices under disrupted conditions. Understanding these driver motivations is important for improving the ability of transportation authorities to plan, design, operate, and maintain transportation networks. The research described in this thesis utilizes a driver survey to investigate the situational factors and personal characteristics that may play a significant role in determining a decision to divert or …

A Fairness Assessment Of Mobility-Based Covid-19 Case Prediction Models, Abdolmajid Erfani, Vanessa Frias-Martinez
Michigan Tech Publications, Part 2
In light of the outbreak of COVID-19, analyzing and measuring human mobility has become increasingly important. A wide range of studies have explored spatiotemporal trends over time, examined associations with other variables, evaluated non-pharmacologic interventions (NPIs), and predicted or simulated COVID-19 spread using mobility data. Despite the benefits of publicly available mobility data, a key question remains unanswered: are models using mobility data performing equitably across demographic groups? We hypothesize that bias in the mobility data used to train the predictive models might lead to unfairly less accurate predictions for certain demographic groups. To test our hypothesis, we applied two …

Research outputs 2022 to 2026
A relationship between the activity of hydrogen ions and charge activity in an aqueous solution has been developed in a previous study. That study also revealed that the potential energy of an aqueous solution can be obtained by multiplying the charge activity with electrostatic potential of the solution. In this study, negative potential energy equalling Gibbs energy of four common salt (NaCl, KCl, NaNO3 and KNO3) solutions were quantified using the charge activity. Then the entropies of those salt solutions were computed using the Gibbs energy, enthalpy, and the charge activity. Charge activities were computed using the pH of those …

A preliminary study found high-performance cement mortar, geopolymer mortar, and magnesium phosphate cement mortar (MPCM) have the potential as new fire-resistant materials. In this study, foam was added to these three fire-resistant materials to further improve their rheological, mechanical, and fire-resistant performance and reduce costs. Systematic design and experimental programs were conducted. The results showed the addition of foam enhanced workability, adhesiveness, and fire resistance, allowing the materials to withstand higher temperatures and further delay heat transfer. A mixture of 70% MPCM and 30% foam was identified as the optimum design, which could withstand 1000 °C with low heat transfer …
