RISModeling Merging Acceleration and Deceleration Behavior Based on Gradient-Boosting Decision Tree
Publisher: ASCE
Abstract: This paper aims to model the behavior of merging acceleration/deceleration when cars are running in a congested weaving section on a freeway during the merging implementation period by using a data-driven method called ...
Characterizing Heterogeneity among Merging Positions: Comparison Study between Random Parameter and Latent Class Accelerated Hazard Model
Publisher: ASCE
Abstract: This study aims to build an accurate merging position model by incorporating heterogeneity into the accelerated hazard model based on random parameter and latent class models. Three kinds of distribution (Weibull, log-normal, ...
Data-Driven Design for a Modified Asphalt Binder Based on a Reduced Order Model and Simplicial Homology Global Optimization
Publisher: ASCE
Abstract: The orthogonal experimental method is currently the most commonly used tool for determining an appropriate composition of modified asphalt binders. However, it cannot automatically output a reasonable composition when ...
Numerical Simulation and Analysis of a Temperature Field in Subsea Caisson
Publisher: American Society of Civil Engineers
Abstract: Subsea oil and gas production systems with caisson are widely utilized in offshore oil and gas resources development. During the development and production processes of oil fields, high-temperature crude oil is transported ...
Two Approaches of the Spring North Atlantic Sea Surface Temperature Affecting the Following July Precipitation over Central China: The Tropical and Extratropical Pathways
Publisher: American Meteorological Society
Abstract: The spring tripole sea surface temperature (SST) anomalies in North Atlantic are an outstanding regional mode of interannual variability. Based on the observed and reanalyzed datasets during 1979–2019, this study reveals ...
