The term Connected Vehicle (CV) is broadly used to identify any ‘smart vehicle’ with wireless connectivity to the roadside infrastructure and other vehicles. CVs that can be driven autonomously are called connected autonomous vehicles (CAVs). With real-time communication and data transmission capability, CAVs have the potential to improve the transportation...
Active traffic management systems aim to relieve recurring and non-recurring congestion by using estimated and predicted traffic conditions to guide trip makers before and after entering the network as well as to design control strategies to improve system performance. With external disruptions and interventions (e.g., weather, special events, and incidents),...
Recently, there has been increasing interest in exploring nano-materials used as an additive to existing concrete materials. With respect to fiber-shaped nanomaterials such as carbon nanofibers (CNF), many studies have shown that mechanical strength properties of cementitious materials can be improved significantly. In this dissertation, the research has focused on...
Precise assessment of long-term aging and deterioration play a major role in life-time predictions of concrete structures. One of the primary challenges in studies of cementitious materials such as concrete comes from the fact that multiple chemical reactions are happening in parallel. Environmental conditions present another challenge as they can...
Reactive Nitrogen (N) and phosphorus (P) pollution is responsible for a vast array of environmental problems, including eutrophication of nutrient limited water bodies, vast dead zones in the ocean margins, and ammonia toxicity to aquatic life. N pollution is also linked to the emission of the potent greenhouse gas nitrous...
Carbon-based materials, such as graphene and carbon fibers, have good prospects for applications in reinforcements of polymers as advanced structural composites. Hence, the study of the mechanical properties of the constituents and the composites is becoming increasingly popular in both academia and industry.', 'Graphene has been shown to have a...
When constructing buildings with basements in urban areas, the deformation levels during the excavation process must be carefully evaluated to prevent or minimize damage to adjacent structures. Because of uncertainties in predicting ground deformations during the design phase for a project, a robust monitoring program should be included in significant...
This dissertation proposes a new hyperpath-based truck equilibrium assignment model with bidding. Unique from other trucking assignment models that examine assigning trucks for a large fleet of vehicles under a company's control, this model considers the case of many independent but homogeneous carriers that are competing for loads by bidding...
The ongoing generational shift whereby millennials are overtaking baby boomers as the largest generation in the U.S. population, along with the technology-fueled evolution of transportation patterns, offer opportunities for policy makers to leverage changing behavior and build a more sustainable future. Much research has emerged seeking to understand whether the...
The advent of next-generation sequencing has made it increasingly feasible to survey microbes in situ, including inside buildings where many people spend extended periods of time. Microbes in buildings, and specifically in dust, are linked to various health outcomes, and the amount of antimicrobial chemicals in dust is associated to...
