Identifying Driving Variables and Paths of Competitive Advantage for International High-Speed Rail Rolling Stock Contractors
(ASCE, 12/1/2021)Competitive advantage is essential for the international high-speed rail (HSR) rolling stock contractors winning orders and surviving in the fierce global market. To achieve it, it is necessary to identify its driving ... -
Risk Assessment Method for High-Speed Railway Track Based on Dynamically Weighted Acceleration
(ASCE, 12/1/2021)As railway maintenance increasingly requires strict inspection and accurate repair, it is urgent to establish a reasonable assessment method for identifying the risks in high-speed railways. Severe track irregularities can ... -
Effect of Residential Building Wind Retrofits on Social and Economic Community-Level Resilience Metrics
(ASCE, 12/1/2021)Tornadoes occur at a high frequency in the United States compared with other natural hazards but have a substantially small footprint. A single high-intensity tornado can result in high casualty rates and catastrophic ... -
Nonlinear Interdependency Measures for Infrastructure Systems: Case Study of Biofuel Infrastructure Development
(ASCE, 12/1/2021)As infrastructure systems become more interconnected and interdependent, the function of one system influences the function of other related systems, which increases their vulnerability to cascading failures. Therefore, ... -
Seismic Rehabilitation Optimization of Water Pipe Networks Considering Spatial Variabilities of Demand Criticalities and Seismic Ground Motion Intensities
(ASCE, 12/1/2021)Operation of critical infrastructure facilities such as hospitals, firefighting stations, and disaster shelters are critical during a postearthquake scenario. The serviceability of many such facilities is, in turn, dependent ... -
Performance Assessment of Oil Supply Chain Infrastructure Subjected to Hurricanes
(ASCE, 12/1/2021)The petroleum industry in the United States relies heavily on facilities in hurricane-prone regions, such as the Gulf Coast. Past hurricanes have demonstrated the vulnerability of petroleum supply chains to these extreme ... -
Heterogeneity-Based Survival Analysis of NBI Condition Ratings for Concrete Highway Bridge Decks in Oregon by Condition Group
(ASCE, 12/1/2021)This study applied a heterogeneity-based survival analysis to determine significant contributing factors to a bridge deck’s time-in-condition rating (TICR) by condition rating (CR) group: high CR, medium CR, and low CR. ... -
Risk-Informed Decision-Making for Predisaster Risk Mitigation Planning of Interdependent Infrastructure Systems: Case Study of Jamaica
(ASCE, 12/1/2021)Hazards cause huge social disruptions and economic losses each year. Community disaster resilience relies on the capacity of critical infrastructure systems to maintain acceptable levels of functionality during a disruptive ... -
New Measure to Understand and Compare Bridge Conditions Based on Inspections Time-Series Data
(ASCE, 12/1/2021)The C+ score for US bridges on the 2017 infrastructure report card underscores the need for improved data-driven methods to understand bridge performance. There is a lot of interest and prior work in using inspection records ... -
Development and Application of Instrumented Bicycle and Its Sensing Technology in Condition Assessments for Bike Trails
(ASCE, 9/1/2021)The paper introduces the development of an instrumented bicycle and its sensing technology and presents a mobile app named Instrumented Bike and a Google Cloud website to demonstrate how the instrumented bicycle advances ... -
Optimal Sampling Locations to Reduce Uncertainty in Contamination Extent in Water Distribution Systems
(ASCE, 9/1/2021)Drinking water utilities rely on samples collected from the distribution system to provide assurance of water quality. If a water contamination incident is suspected, samples can be used to determine the source and extent ... -
Integrated Evolutionary Algorithms/Computational Fluid Dynamics for Drag Reduction in Highway Design
(ASCE, 9/1/2021)Reducing ground vehicle emissions can have substantial economic and environmental benefits. A possible way to promote this goal is by redesigning highway infrastructure to reduce aerodynamic drag on vehicles. This paper ... -
Accounting for Source Location on the Vulnerability Assessment of Water Distribution Network
(ASCE, 9/1/2021)The vulnerability of water distribution networks (WDNs) to water-main breaks is used for prioritizing pipes in the network for maintenance planning. In this paper, a parameter of graph theory, algebraic connectivity (AC), ... -
Impact of Highway Nonuser Revenue on Equity Ratio: Exploratory Analysis
(ASCE, 9/1/2021)In the United States, due to the continued decline of highway user revenues from traditional sources, many states have adopted the approach of using highway nonuser revenue sources to support highway infrastructure ... -
Simulation of Railway Drainage Asset Service Condition Degradation in the UK Using a Markov Chain–Based Approach
(ASCE, 9/1/2021)UK railway drainage systems are facing increasing challenges due to poor completeness of the asset inventory, long asset life cycles, more intense use of the UK railway system, and a changing climate. It is therefore ... -
Combining Machine Learning and Survival Statistics to Predict Remaining Service Life of Watermains
(ASCE, 9/1/2021)Distribution systems throughout North America are deteriorating and pipe breaks are increasing. To deal with these infrastructure crises, utilities have begun to adopt proactive pipe replacement models to determine which ... -
Anticipated User Equity Impacts of a Proposed Transportation Infrastructure Finance Legislation: Case Study in Indiana
(ASCE, 9/1/2021)State and city governments in the United States continue to emphasize user equity in all transportation policy areas, including project evaluation, finance, and operations. In 2016, the State of Indiana House of Representatives ... -
Pavement Deterioration Modeling and Network-Level Pavement Management Using Continuous Deflection Measurements
