Transportation Infrastructure Protection Planning against Sea Level Rise: Analysis Using Operational Landscape Units
(American Society of Civil Engineers, 2019)This paper addresses the problem of the optimal coastal protection area against sea level rise by utilizing fine-grained homogeneous segments, namely, operational landscape units (OLUs). The approach is demonstrated through ... -
Examining Relationship between Infrastructure Investment and Performance Using State-Level Data
(American Society of Civil Engineers, 2019)Oversight organizations seek to monitor regularly the expenditures and the resulting performance of infrastructure agencies under their authority. A context of this expenditure–performance connection is that of infrastructure ... -
In Situ Detection of Tree Root Systems under Heterogeneous Anthropogenic Soil Conditions Using Ground Penetrating Radar
(American Society of Civil Engineers, 2019)Tree roots can cause damage to surface and subsurface infrastructure. Hence, timely detection of root system architecture (RSA) is needed to reduce conflict between trees and man-made facilities. Because excavation is ... -
Foreign Direct Investment in Infrastructure Projects: Taxonomy of Political Risk Profiles in Developing Countries
(American Society of Civil Engineers, 2019)Political risk is a recognized deterrent to foreign direct investment in infrastructure (FDII) in developing countries. The sensitivity of FDII to political risk is amplified above that of common foreign direct investment ... -
Anomalies in External Construction Elements in Spain according to Cause-Damage Relationship
(American Society of Civil Engineers, 2019)This paper’s objective is to determine the usual typologies of deficiencies in external construction elements, identifying the most frequently recurring anomalies by analyzing all judicial complaints pertaining to construction ... -
Statistical Inference of Sewer Pipe Deterioration Using Bayesian Geoadditive Regression Model
(American Society of Civil Engineers, 2019)Several deterioration models have been developed for prediction of the actual and future condition states of individual sewer pipes. However, most tools that have been developed assume a linear dependency between the ... -
Novel System for Rapid Investigation and Damage Detection in Cultural Heritage Conservation Based on Deep Learning
(American Society of Civil Engineers, 2019)Rapid investigation and damage assessment are crucial for cultural heritage conservation. At present, mobile crowd sensing (MCS) techniques are very effective for cultural heritage investigation and data collection. ... -
Embedding Flexibility within Pavement Management: Technique to Improve Expected Performance of Roadway Systems
(American Society of Civil Engineers, 2019)Pavement-management systems are important tools that planning agencies depend on to cost-effectively maintain their roadway systems. The incorporation of uncertainty (beyond that related to pavement degradation) within ... -
Validity and Reliability of Drainage Infrastructure Monitoring Data Obtained from Citizen Scientists
(American Society of Civil Engineers, 2019)Data on the quality of small-scale infrastructure assets at the neighborhood level tend to be scarce, delayed, or even nonexistent, limiting the ability of local communities to better manage assets, identify risks, and ... -
Service Value and Componentized Accounting of Infrastructure Assets
(American Society of Civil Engineers, 2019)Asset management is a strategic tool for maintaining the value of an asset at a level that is satisfactory for users, asset owners, and taxpayers. This paper introduces the concept of service value. The concept is applied ... -
Economics of Making Roadway Pavements Resilient to Climate Change: Use of Discounted Cash Flow and Real Options Analysis
(American Society of Civil Engineers, 2019)An increase in the number of extreme weather events and gradual shifts in climate parameters due to a changing climate pose a serious threat to the nation’s roadway infrastructure. A systematic approach is needed to define ... -
Smartphone-Based Pothole Detection Utilizing Artificial Neural Networks
(American Society of Civil Engineers, 2019)Roadway pavement maintenance to the preferred level of serviceability comprises one of the most challenging problems faced by civil and transportation engineers, with regard to transport infrastructure management. This ... -
Development of Zonal-Specific Semivariograms for a Strategic RWIS Network Optimization: Case Study
(American Society of Civil Engineers, 2019)This paper presents a study aimed at developing zonal-specific semivariograms for zones with different climates using regionalized random variables for a strategic road weather information system (RWIS) network implementation ... -
Systematic Assessment of Nondestructive Evaluation Techniques for Post-Tensioning and Stay Cable Systems
(American Society of Civil Engineers, 2019)Nondestructive evaluation (NDE) can provide invaluable information about the condition of tendons in post-tensioned and cable-stayed bridges, which can facilitate preventative actions to mitigate further deterioration. To ... -
Resilience Evaluation Framework for Integrated Civil Infrastructure–Community Systems under Seismic Hazard
(American Society of Civil Engineers, 2019)Seismic resilience of civil infrastructure systems is an essential property of modern communities. In this paper, an agent-based modeling framework to evaluate the seismic resilience of an integrated system consisting of ... -
Interdiction-Based Approaches to Identify Damage in Disrupted Critical Infrastructures with Dependencies
(American Society of Civil Engineers, 2019)In this paper, we consider a problem in which the decision maker only has access to outage reports from service receivers in critical infrastructures with dependencies among them, and our objective is to determine inspection ... -
Automated Rust-Defect Detection of a Steel Bridge Using Aerial Multispectral Imagery
(American Society of Civil Engineers, 2019)Computer vision methods have the potential to detect rust defects in steel components of bridges. However, direct use of images collected by aerial means to identify such defects is currently difficult because of obstructions ... -
How Spatial and Functional Dependencies between Operations and Infrastructure Leads to Resilient Recovery
