Extraction of Nonlinear Aerodynamic Damping of Crosswind-Excited Tall Buildings from Aeroelastic Model Tests
Publisher: ASCE
Abstract: This paper presents a new approach for extracting nonlinear aerodynamic damping of crosswind-excited tall buildings from response statistics at different levels of structural damping obtained from aeroelastic model tests. ...
Control Strategy for Ramp Traffic Based on Improved ALINEA Algorithm
Publisher: American Society of Civil Engineers
Abstract: This study presents a ramp control strategy that builds upon the ALINEA framework to enhance the throughput of expressways equipped with vehicles-to-everything capabilities. The conventional ALINEA control strategy relies ...
Stability Analysis and Speed-Coordinated Control of Mixed Traffic Flow in Expressway Merging Area
Publisher: ASCE
Abstract: This paper considers the stability of mixed traffic flow and the necessity of speed control to achieve safety and efficiency goals. Therefore, a speed-coordinated control model is proposed for mixed traffic flow based on ...
Improving the Model Convective Storm Quantitative Precipitation Nowcasting by Assimilating State Variables Retrieved from Multiple-Doppler Radar Observations
Publisher: American Meteorological Society
Abstract: his research combines an advanced multiple-Doppler radar synthesis technique with the thermodynamic retrieval method, originally proposed by Gal-Chen, and a moisture/temperature adjustment scheme, and formulates a sequential ...
Dependence of Beaufort Sea Low Ice Condition in the Summer of 1998 on Ice Export in the Prior Winter
Publisher: American Meteorological Society
Abstract: Four events of distinctly low summer ice coverage in the Beaufort Sea, in 1998, 2008, 2012, and 2016, have been identified using satellite-observed concentration between 1979 and 2017. Previous studies have revealed that ...
Two-Step Coordinated Optimization Model of Mixed Demand Responsive Feeder Transit
Publisher: ASCE
Abstract: It is necessary to consider both the reservation and real-time travel demand in order to coordinate and optimize vehicle routing and scheduling. In this paper, a two-step coordinated optimization methodology is proposed ...
