Perceived Effectiveness of Highway Work Zone Intrusion Mitigation Technologies: A State DOT Perspective

Creator:: Kadalli, Manjunath Veeresh
Abstract:: Highway work zones are extremely dangerous environments due to the presence of workers near high-speed traveling vehicles. This dynamic environment results in a disproportionate number of accidents that cause injury and casualty to both drivers and workers due primarily to vehicular intrusions into work zones. Several emerging work zone intrusion...

Application of Technologies for Temporary Structures during the Design and Construction Phases

Creator:: Jin, Ziyu
Abstract:: The development of technologies such as Building Information Modeling (BIM), light detection and ranging (lidar), and sensor-based systems poses new opportunities for researchers to rethink how construction safety and health can be approached during the design, planning, and construction phases of a project. Nevertheless, the majority of the technology applications...

Evaluating Worker Performance Using the Energy Concept

Creator:: Alotaibi, Abdulaziz M.
Abstract:: Over the decades, worker performance on construction projects has been a significant source of concern to be evaluated. Comprehensive studies have developed models for evaluating worker performance outside of the construction industry; however, minimal research has been conducted to evaluate worker performance in the construction industry. One of the reasons...

Decision-making Tool to Select Construction Contractors Based on Safety Performance

Creator:: Al-Saffar, Ola T.
Abstract:: The safety of workers in the construction industry is a big concern because of the high number of fatalities and injuries that occur in the industry. Selecting contractors based on safety performance can improve safety and reduce the risks of injuries. However, owners commonly choose contractors based on competitive bidding...

Best Practices for Work Zone Safety during Traffic Control Placement, Removal, and Modification

Creator:: Moeung, Serey Raksa
Abstract:: Previous research has shown that traveling in a work zone involves a higher risk of crashing compared to normal (non-work zone) driving conditions. Research further suggests that the severity of work zone crashes is greater on average than non-work zone crashes. The period of time in which the traffic control...

Evaluation of the Efficiency of Supplementary Cementitious Materials to Prevent Alkali-Silica Reaction in Concrete with Highly and Very Highly Reactive Aggregates

Creator:: Chopperla, Krishna Siva Teja
Abstract:: The most common test methods to evaluate alkali-silica reaction (ASR), the concrete prism test (CPT) and the accelerated mortar bar tests (AMBT), have limitations and are not entirely reliable in terms of predicting the performance of concrete with prevention measures under field conditions. In this study, the miniature concrete prism...

Evaluating the Feasibility of Mass Timber as a Mainstream Building Material in the US Construction Market: Industry Perception, Cost Competitiveness, and Environmental Performance Analysis

Creator:: Ahmed, Shafayet
Abstract:: Mass timber has been considered as a promising building material because of its structural rigidity, environmental sustainability, and renewability nature. In Europe and Australia, mass timber materials have been used for many different types of construction such as residential, commercial, education, and industrial. However, the construction practitioners in the U.S....

Design Principles of Transition Metal X-ide Catalysts for Electrochemical Oxygen Reduction and Evolution Reactions: In-Situ X-ray Spectroscopy Studies

Creator:: Wang, Maoyu
Abstract:: Hydrogen is the green fuel that can be produced from water through electrolysis and used via hydrogen fuel cells to generate electricity with zero carbon dioxide emission. The commercialization of electrolyzers and fuel cells is the critical step to achieving global carbon neutrality. However, it is severely hampered by the...

Use of Flashing Lights in Traffic Safety of Vulnerable Road Users

Creator:: Ahmed, Ananna
Abstract:: Vulnerable road users, anyone interacting with the roadway facility without the protection of an automobile, experience greater risk for more severe crash outcomes. Multimodal roadway facilities often times provide less separation and more points of conflict between different types of road users. To promote vulnerable road user safety, transportation agencies...

Assessing the Trade-Off Between Sustainability and Resiliency of Reinforced Concrete Alternatives in Corrosive Conditions: An LCA-System Dynamics Approach

Creator:: Moreno Rangel, Erick D.
Abstract:: Concrete has been categorized as a key contributor of CO2 (carbon) emissions into the atmosphere. This is mostly associated with the production of ordinary portland cement (OPC). The concrete and cement industries are pursuing a path to reduce their carbon emissions generally in accordance with the climate change goals outlined...
