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 ... -
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 ... -
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, ... -
Bridge Infrastructure Asset Management System: Comparative Computational Machine Learning Approach for Evaluating and Predicting Deck Deterioration Conditions
(ASCE, 9/1/2020 1)Bridge infrastructure asset management system is a prevailing approach toward having an effective and efficient procedure for monitoring bridges through their different development phases including construction, operation, ... -
Predicting Bicycle Pavement Ride Quality: Sensor-Based Statistical Model
(ASCE, 9/1/2020 1)Bicycle paths or even bicycle lanes have not emerged as key priorities in traditional pavement systems analysis. Most cities rely on route preferences (e.g., common school routes) or visual checks to prioritize pavement ... -
Design of a Multiperiod Tradable Credit Scheme under Vehicular Emissions Caps and Traveler Heterogeneity in Future Credit Price Perception
(ASCE, 9/1/2020 1)The transportation sector is a major source of traffic congestion and greenhouse gas (GHG) emissions in urban areas. This study aims to design the system-optimal (SO) traffic management policy, i.e., multiperiod ... -
Model for Estimating the Impact of Interdependencies on System Recovery
(ASCE, 9/1/2020 1)Infrastructure interdependencies have been widely recognized, especially in the postdisaster restoration process. It is essential to develop models to simulate interdependencies and quantify their impact on the functionality ... -
Investment Valuation of Underground Freight Transportation Systems under Uncertainty
(ASCE, 9/1/2020 1)Investment valuation of underground freight transportation (UFT) systems is subject to a high level of uncertainties, including construction cost fluctuations and shipment revenue variations. Real options analysis is known ... -
Past and Present Design Practices and Uncertainty in Climate Projections are Challenges for Designing Infrastructure to Future Conditions
(ASCE, 9/1/2020 1)Designing infrastructure for a changing climate remains a major challenge for engineers. In popular discourse a narrative has emerged that infrastructures are likely underdesigned for the future. Weather-related hazards ... -
Hybrid Method of Recovery: Combining Topology and Optimization for Transportation Systems
(ASCE, 9/1/2020 1)Designing effective recovery strategies for damaged networks is important across built, human, and natural systems. Postperturbation network recovery has been motivated by two distinct philosophies, specifically, the use ... -
Emergency Response after Disaster Strikes: Agent-Based Simulation of Ambulances in New Windsor, NY
(ASCE, 9/1/2020 1)Emergency medical services (EMS) rely on a robust road network to respond to patient demand as quickly as possible. An important measure of system effectiveness during adverse scenarios, such as heavy traffic and road ... -
Hierarchical Approach for Assessing the Vulnerability of Roads and Bridges to Flooding in Massachusetts
(ASCE, 9/1/2020 1)The current study addresses the issue of vulnerability assessment of transportation systems to climate change, with the purpose of improving current indicator-based approaches in this field. It builds upon other efforts ... -
Water Distribution–Transportation Interface Connectivity Responding to Urban Geospatial Morphology
(ASCE, 9/1/2020 1)Water distribution and transportation systems are geospatially colocated, forming a network of connections. This network of connections is referred to as an interface network. Investigation of interface network connectivity ... -
Triple Top Line–Based Sustainability Measure for Water Distribution Systems
(ASCE, 9/1/2020 1)To address the rapidly growing need for asset management of aging water distribution systems (WDS), this study introduces the adaptation of the triple top line (TTL) as a tool for WDS sustainability evaluation. The WDS TTL ... -
Preliminary Development of an ME-Based Wearing Model for the Conductor Rail in MCTS
