RISVariability and Predictability of Basinwide and Sub-Basin Tropical Cyclone Genesis Frequency in the Northwest Pacific
Publisher: American Meteorological Society
Abstract: The variability and predictability of tropical cyclone genesis frequency (TCGF) during 1973–2010 at both basinwide and sub-basin scales in the northwest Pacific are investigated using a 100-member ensemble of 60-km-resolution ...
Gray System Model for Estimating the Pavement International Roughness Index
Publisher: American Society of Civil Engineers
Abstract: The international roughness index (IRI) is a measurement of pavement roughness that is widely accepted for evaluating pavement serviceability, especially its riding quality. Generally, as the age of pavement increases, its ...
Assessing Pavement Friction Need for Safe Integration of Autonomous Vehicles into Current Road System
Publisher: ASCE
Abstract: 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 ...
Determination of Optimal Pretreatment Method for Existing Pavement Surface in High-Friction Surface Treatment Construction
Publisher: ASCE
Abstract: This paper presents the research approach and the test data, analysis results, and findings from a study that comprehensively investigated the possible effects of existing pavement, especially chip seal and its surface ...
Line-of-Sight Wall versus Conventional Noise Wall for Traffic Noise Abatement: Field Performance Comparison
Publisher: American Society of Civil Engineers
Abstract: The constructed cost of conventional noise walls is about $2 million per linear mile. In many areas, the cost-effectiveness criteria of $25,000 per benefited receiver are exceeded so that these areas are not eligible for ...
Evaluation of Pavement Friction Performance on Interchange Ramps at Network Level
Publisher: American Society of Civil Engineers
Abstract: Most state highway agencies conduct inventory friction testing on mainline highways to monitor network pavement friction performance. However, no state highway agencies have been reported to monitor pavement friction ...
An Adaptive Two-Stage Kriging-Based Infilling Strategy for Efficient Multi-Objective Global Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Most practical multi-objective optimization problems are often characterized by two or more expensive and conflicting objectives, which require time-consuming simulations. Commonly used algorithms construct a surrogate ...
Physical and Mechanical Properties of Epoxy–Bauxite Mortar of High-Friction Surface Treatment
Publisher: ASCE
Abstract: Highfriction surface treatment (HFST) has been widely utilized by state departments of transportation (DOTs) to reduce friction related vehicle crashes. However, although many studies have been conducted to enhance the ...
Laboratory Evaluation of Critical Properties and Attributes of Calcined Bauxite and Steel Slag Aggregates for Pavement Friction Surfacing
Publisher: American Society of Civil Engineers
Abstract: The long-term friction performance of safety-focused friction surfacing, especially high-friction surface treatment (HFST), relies primarily on the properties of aggregate. Nevertheless, inconsistencies exist in the ...
