RISIRI Estimation Based on Pavement Distress Type, Density, and Severity: Efficacy of Machine Learning and Statistical Techniques
Publisher: ASCE
Abstract: The International Roughness Index (IRI) is widely used in evaluating pavement condition, making repair decisions, assessing ride comfort, and estimating vehicle operating costs. However, it is generally costly to measure ...
Extracting Topographic Data from Online Sources to Generate a Digital Elevation Model for Highway Preliminary Geometric Design
Publisher: American Society of Civil Engineers
Abstract: Two principal aspects of preliminary highway design are detailed characterization of the geographic and topographic features along potential candidate alignments and preliminary design of the highway along at least one of ...
Methodology for Probabilistic Modeling of Highway Bridge Infrastructure Condition: Accounting for Improvement Effectiveness and Incorporating Random Effects
Publisher: American Society of Civil Engineers
Abstract: The peculiar nature of bridge infrastructure condition data persistently poses challenges in predicting bridge component deterioration that necessitate the continued investigation of probabilistic modeling techniques. These ...
Examining Relationship between Infrastructure Investment and Performance Using State-Level Data
Publisher: American Society of Civil Engineers
Abstract: 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 ...
Repositioning Shared Urban Personal Transport Units: Considerations of Travel Cost and Demand Uncertainty
Publisher: ASCE
Abstract: 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, ...
