Modeling Regional Hurricane Evacuation Events: Calibration and Validation
Publisher: American Society of Civil Engineers
Abstract: Calibration and validation of traffic models is a necessary step to better fit model output to real-world conditions. Presently, there has been little research in this particular area of evacuation modeling because of a ...
Freeway Traffic Speed Estimation by Regression Machine-Learning Techniques Using Probe Vehicle and Sensor Detector Data
Publisher: ASCE
Abstract: In the literature, machine-learning techniques have been extensively implemented to capture the stochastic characteristics of freeway traffic speed. The deployment of intelligent transportation systems (ITSs) in recent ...
A Transfer Learning–Based LSTM for Traffic Flow Prediction with Missing Data
Publisher: ASCE
Abstract: Traffic flow prediction plays an important role in intelligent transportation systems (ITS) on freeways. However, incomplete traffic information tends to be collected by traffic detectors, which is a major constraint for ...
Effect of Porosity on the Prediction of Natural Frequencies of Cylindrical Rock Samples: Analytical Model and Experiments
Publisher: American Society of Civil Engineers
Abstract: The prediction of natural frequencies of porous rock samples is essential for investigating their dynamic behaviors. Utilizing a cylinder vibration model governed by the Lame–Navier equation, a novel analytical model was ...
Flow in Helical Annular Pipe
Publisher: American Society of Civil Engineers
Abstract: In this paper, the axial and the secondary flow in a helical annular pipe are examined by a perturbation method in a curvilinear coordinate system, and the second-order perturbation solution is obtained completely. The ...
An Investigation of the Influence of Reconsolidation Properties on the Reliquefaction Resistance of Sand by Element Tests
Publisher: ASCE
Abstract: Site survey revealed that a liquefiable sand layer was often sandwiched by low-permeable layers with fine particles, which could hinder the dissipation of excess pore water pressure (EPWP) after earthquake excitation. ...
Integrated Optimization of Seat Allocation for High-Speed Trains and Tour Buses Based on Customized Travel Services
Publisher: American Society of Civil Engineers
Abstract: The provision of diverse transportation modes for tourism is primarily driven by individual demand, which ultimately leads to a lack of cohesive capacity allocation among different modes of transportation. This inadequacy ...
Self-Balancing of an Open–Close Pumping Station Based on the Second-Order Integrator-Delay Model
Publisher: American Society of Civil Engineers
Abstract: To minimize unit switching, this study investigates the scheduling optimization of open–close pumping stations (OCPS) by focusing on the concept of pumping station self-balancing (PSSB). Specifically, a novel regulatory ...
Hydraulic Optimization Control of Cascaded Open Channel under the Emergency Scenario of a Downstream Water Supply Interruption
Publisher: ASCE
Abstract: Downstream water supply disruption accidents commonly occur in the large-scale cascade open-channel dispatching system, endangering dispatch safety. The emergency reaction requires active drainage water volume and cost ...
Creep Behavior of Rocks with Rough Surfaces
