Preliminary Development of an ME-Based Wearing Model for the Conductor Rail in MCTS
(ASCE, 12/1/2020 )Rubber-tired trains are powered by electricity through sliding contact between the conductor rail system and collector shoe. The sliding contact produces wear on the conductor rail and wear plate, which results in malfunctions ... -
Smart Data Management of Urban Infrastructure Using Geographic Information Systems
(ASCE, 12/1/2020 )Cities all over the world are converting maps of their infrastructure systems from legacy formats [such as paper maps and computer-aided design (CAD) drawings] to geographic information systems (GIS). Compared with CAD, ... -
Hindcasting the Functional Loss and Restoration of the Napa Water System Following the 2014 Earthquake Using Discrete-Event Simulation
(ASCE, 12/1/2020 )Models that simulate postearthquake functional loss and restoration of water distribution systems support the development and implementation of more informed resilience-enhancing strategies. This study uses pipe damage, ... -
Asset Management Framework for Integrated Municipal Infrastructure
(ASCE, 12/1/2020 )Municipalities are experiencing high inefficiency and financial burden imposed by their underperforming aging infrastructure. One-third of Canada’s municipal infrastructure is in fair, poor, and failing condition states, ... -
Analyzing the Hybrid Financing Deep-Discount Project Bonds and Land Leases for a New Toll Road Financing Model
(ASCE, 12/1/2020 )Infrastructure has been discovered to be the backbone of an economy due to its influence on business and productivity. However, a significant investment funding gap was observed in infrastructural projects, particularly ... -
Wavelet-Entropy Approach for Detection of Bridge Damages Using Direct and Indirect Bridge Records
(ASCE, 12/1/2020 )Bridges as a key component of road networks require periodic monitoring to detect structural degradation for early warning. Early detection of loci and extent of structural flaws is essential to maintain safe bridge ... -
Governance Issues in PPP Procurement Options Analysis of Social Infrastructure: Case of Indian Waste Management Sector
(ASCE, 12/1/2020 )This paper assesses the impact of procurement strategies on the local governments’ service delivery in the context of India. The validity of the rhetorical arguments previously developed in the extant literature—innovation, ... -
Critical Failure Drivers in International Water PPP Projects
(ASCE, 12/1/2020 )The public-private partnership (PPP) scheme has been applied for many years as an effective approach in improving water infrastructure and services. However, the failure of many water PPP projects is eroding public confidence ... -
Infrastructure Interdependencies: Opportunities from Complexity
(ASCE, 12/1/2020 )Infrastructure networks, such as those for energy, transportation, and telecommunications, perform key functions for society. Although such systems have largely been developed and managed in isolation, infrastructure now ... -
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 ... -
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 ... -
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 ... -
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 ... -
Integrated Planning of Operational Maintenance Programs for Water and Gas Distribution Networks
(ASCE, 12/1/2021)Drinking water and natural gas are essential goods provided by municipal distribution networks. In order for there to be a reliable provision of such commodities, infrastructure managers must regularly dispatch vehicles ... -
Coopetition Strategies of International Joint Ventures for High-Speed Railway Projects
