Evaluation of the Consistency of Bridge Inspection Ratings in New York State
(ASCE, 9/1/2021)Previous studies by the Federal Highway Administration (FHWA) have shown significant variability in the rating of bridge elements through visual inspection. In this study, a detailed evaluation of the consistency of ... -
Repositioning Shared Urban Personal Transport Units: Considerations of Travel Cost and Demand Uncertainty
(ASCE, 9/1/2021)Operators of personal transport units (PTUs) face the challenge of intelligently balancing the locational demand and supply of PTUs in order to mitigate surpluses or deficits at PTU pickup stations. To accomplish this goal, ... -
Automated Framework to Audit Traffic Signs Using Remote Sensing Data
(ASCE, 9/1/2021)Traffic signs play a critical role in the safety and efficiency of any roadway; however, limited information exists on current traffic sign inventories (TSIs). The size of current traffic sign networks makes it economically ... -
Risk-Based Metanetwork Modeling for Sustainable Project Performance in International Construction
(ASCE, 9/1/2021)International construction is a high-risk undertaking with multiple objectives and uncertainties. This study aims to clarify the complex relationships between the risks of international construction and the objectives of ... -
Enhanced Safety Performance Function for Highway Segments in Oklahoma
(ASCE, 9/1/2021)A safety performance function (SPF) is a statistical equation to predict the expected crash frequency for a certain roadway facility, mainly as a function of traffic exposure indicators. Roadway characteristics, such as ... -
Assessing Pavement Friction Need for Safe Integration of Autonomous Vehicles into Current Road System
(ASCE, 6/1/2021)Safe integration of autonomous vehicles (AVs) into the current public road system may imply potential improvements to roadway infrastructure. However, the current research effort is lacking in one of the important ... -
Subway Ridership: Accounting for Regional Variation across Land-Use and Socioeconomic Settings
(ASCE, 6/1/2021)Accurate forecasts of public transportation ridership are key components to a transit agency’s management program. These forecasts are used to develop revenue projections that are then imputed into short-term and long-term ... -
Effects of Cement Changes and Aggregate System on Mechanical Properties of Concrete
(ASCE, 9/1/2021)In this study, the mechanical properties of concrete mixtures containing different cementitious combinations and two aggregate systems were investigated under plastic and drying conditions. Emphasis was laid on the durability ... -
Evaluating the Corruption Susceptibility Index of Infrastructure Procurement and Management in the Developed Context: The Case of Hong Kong
(ASCE, 6/1/2021)This study evaluates the susceptibility patterns of the procurement process of infrastructure projects to corruption in Hong Kong. An expert survey is conducted with infrastructure-related professionals from Hong Kong (HK) ... -
Assessing the Policy Provisions and Institutional Behavioral Factors Influencing Rail Infrastructure Financing in Developing Countries
(ASCE, 6/1/2021)Financing rail infrastructure development in developing countries has hitherto received scant academic attention, especially in empirical developments. This research study assesses the policy provisions and institutional ... -
Societal Impacts of a Complete Street Project in a Mixed Urban Corridor: Case Study in Pittsburgh
(ASCE, 6/1/2021)Complete streets facilitate multimodal travel by improving both transportation access and safety by emphasizing the user, not the automobile. This case study evaluates the impacts of a complete street retrofit on a mixed ... -
Implications of Climate Change Mitigation and Household Water Saving in Existing Water Networks: Upgrade Requirements and Hydraulic Perspectives
(ASCE, 6/1/2021)Climate change and the ever-increasing water demands have led to the introduction of mitigation and adaptation interventions in water systems, which need to be understood. The effects of these countermeasures on the upgrade ... -
Life-Cycle Cost Analysis of Deteriorating Civil Infrastructures Incorporating Social Sustainability
(ASCE, 9/1/2021)Social sustainability has rarely been considered in the design and management of civil infrastructures. This paper presents a two-level, six-category classification of social impacts regarding civil infrastructures and the ... -
Assessing the System Resilience Trade-Off Space: Empirical Model of the Port of Houston Waterway Recovery Process
(ASCE, 6/1/2021)When they are disrupted, complex, technical-social systems, such as maritime ports, require operators to negotiate a resilient solution that satisfies a broad range of individual business and societal needs without ... -
Accuracy of Drone-Based Surveys: Structured Evaluation of a UAS-Based Land Survey
(ASCE, 6/1/2021)A recent study concluded that the use of unmanned aerial systems (UAS) could benefit state departments of transportation in four key ways, one of which was the creation of preconstruction surveys. This study investigated ... -
Comparative Analysis of Markovian Methodologies for Modeling Infrastructure System Performance
(ASCE, 6/1/2021)Various types of Markov chain methodologies have been used in past research to develop stochastic performance models for infrastructure systems—the staged-homogeneous, nonhomogeneous, homogeneous, semi-, and hidden Markov. ... -
Proactive Operations and Investment Planning via Stochastic Optimization to Enhance Power Systems’ Extreme Weather Resilience
(ASCE, 6/1/2021)We present scalable stochastic optimization approaches for improving power systems’ resilience to extreme weather events. We consider both proactive redispatch and transmission line hardening as alternatives for mitigating ... -
