Maintenance And Restriping Strategies For Pavement Markings On Asphalt Pavements In Louisiana, Momen R. Mousa, Marwa Hassan Aug 2021

Maintenance And Restriping Strategies For Pavement Markings On Asphalt Pavements In Louisiana, Momen R. Mousa, Marwa Hassan

Data

In Louisiana, most districts restripe their roadways using waterborne paints every other year; this strategy is questionable in terms of efficiency and economy. Meanwhile, previous studies showed substantial variability in the paint service life throughout the United States ranging between 0.25 and 6.2 years. Shortcomings in modeling the retroreflectivity of waterborne paints appear to significantly contribute to these variations as several studies predicted these values using degradation curves with a coefficient of determination (R2) as low as 0.1. Therefore, the objective of this study was to (i) develop new cost-effective restriping strategies using 4-inch (15-mil thickness) and 6-inch (25-mil thickness) …

High-Density Parking For Autonomous Vehicles., Parag J. Siddique Aug 2021

High-Density Parking For Autonomous Vehicles., Parag J. Siddique

Electronic Theses and Dissertations

In a common parking lot, much of the space is devoted to lanes. Lanes must not be blocked for one simple reason: a blocked car might need to leave before the car that blocks it. However, the advent of autonomous vehicles gives us an opportunity to overcome this constraint, and to achieve a higher storage capacity of cars. Taking advantage of self-parking and intelligent communication systems of autonomous vehicles, we propose puzzle-based parking, a high-density design for a parking lot. We introduce a novel method of vehicle parking, which leads to maximum parking density. We then propose a heuristic method …

Assessing The Impact Of Health Benefits And Carbon Footprint In Student Parking Decisions At A University Campus, Emiliano Ruiz Aug 2021

Assessing The Impact Of Health Benefits And Carbon Footprint In Student Parking Decisions At A University Campus, Emiliano Ruiz

Open Access Theses & Dissertations

In the student parking location problem, traditionally, the parking permit cost, the last-mile travel time, and the ease of finding an available parking stall are the only decision criteria driving permit purchases. However, a studentâ??s choice of parking location has associated walking health benefits and sustainability impacts. These impacts are related to the walking distance from the parked vehicle to the final destination on campus, in addition to the location effect on the carbon footprint of a vehicle-trip taken to campus. As such, this Thesis examined a multi-criteria decision approach to a university studentâ??s choice of parking location. This approach …

Harmonizing Asphalt Mix Selection With Pavement Structural Design, Mahdi Saghafi Aug 2021

Harmonizing Asphalt Mix Selection With Pavement Structural Design, Mahdi Saghafi

Open Access Theses & Dissertations

The state-of-the-practice in asphalt concrete (AC) mix design and pavement structural design are based on two divergent concepts. The laboratory tests that are used for mix design, especially under the balanced mix design concept, are pragmatically accelerated surrogate tests developed to ensure the stability or ranking of mixes. Pavement structural design methods, being empirical or mechanistic, ignore these laboratory test results, in favor of other mechanical parameters. As such, the selection of the type of mix to be placed on a project is based on the local experience, and a set of consensus limits, rather than the demand of the …

Electrical Characterization Of Conductive Concrete Containing Graphite Powder, K. I. M. Iqbal Aug 2021

Electrical Characterization Of Conductive Concrete Containing Graphite Powder, K. I. M. Iqbal

Theses and Dissertations

Electrically conductive concrete has various potential non-structural functions such as self-sensing, de-icing, and electromagnetic shielding. Since conductive concrete is a composite containing moisture and discrete conductive additives, its electrical properties are very complex. Understanding these properties is the fundamental requirement for developing its non-structural applications. In this research, graphite powder is used as a conductive additive with varying percentages (0% to 30%) by cement paste volume. Both AC impedance analysis and DC measurement are performed in both wet and dry conditions. The results show that the resistivity measured by DC are not consistent because of polarization before/during the measurement. On …

Investigating Adoption Behavior Of Owned And Shared Autonomous Vehicles: An Updated Technology Acceptance Model, Yellitza Soto Aug 2021

Investigating Adoption Behavior Of Owned And Shared Autonomous Vehicles: An Updated Technology Acceptance Model, Yellitza Soto

Theses and Dissertations

Transportation systems will be likely transformed by the emergence of autonomous vehicles (AVs), either owned privately or used in a shared system (SAVs), which promise for safe, convenient, and efficient mobility, to name a few benefits to the society. The manifestation of (S)AV benefits, however, is still dubious due to the observed public reluctance, or at best neutrality, towards (S)AVs, especially SAVs. The public's perception towards these innovations is still unclear, therefore, a gap remains in the analysis of individuals’ behavioral intention (BI) to use AVs and SAVs. To fill that gap, this study uses a behavioral psychology method. Specifically, …
