Two 4D Models Effective in Reducing False Alarms for Struck-by-Equipment Hazard Prevention
Publisher: American Society of Civil Engineers
Abstract: Over the past decade, several smart and automated systems have been developed to address the issue of struck-by hazards in construction—that is, workers on foot struck by equipment or equipment struck by equipment. False ...
Comparison of Neural and Conventional Approaches to Mode Choice Analysis
Publisher: American Society of Civil Engineers
Abstract: This paper describes a new approach to behavioral mode choice modeling using neurofuzzy models. The new approach combines the learning ability of artificial neural networks and the transparent nature of fuzzy logic. The ...
Streamflow Prediction in Ungauged Basins: Review of Regionalization Methods
Publisher: American Society of Civil Engineers
Abstract: This paper presents a comprehensive review of a fundamental and challenging issue in hydrology: the regionalization of streamflow and its advances over the last two decades, specifically 1990–2011. This includes a discussion ...
Foreseeability in Construction
Publisher: American Society of Civil Engineers
Variable Speed Limit for Freeway Work Zone with Capacity Drop Using Discrete-Time Sliding Mode Control
Publisher: American Society of Civil Engineers
Abstract: Freeway work zone with lane closure has a direct negative impact on travel time, safety, and environmental sustainability. The capacity drop at the onset of the congestion can also further reduce the discharging rate at ...
Policy Analysis of Adaptive Traffic Signal Control Using Reinforcement Learning
Publisher: ASCE
Abstract: Previous research studies have successfully developed adaptive traffic signal controllers using reinforcement learning; however, few have focused on analyzing what specifically reinforcement learning does differently than ...
Spatiotemporal Network-Based Model for Dynamic Risk Analysis on Struck-by-Equipment Hazard
Publisher: American Society of Civil Engineers
Abstract: Having an approach that can analyze and identify safety risks in the dynamic and hazardous construction environment is one of the key steps to the success of health and safety plans. Struck-by-equipment hazard is one of ...
Implementation of a Nonlinear State–Dilatancy Law in the NorSand Model
Publisher: American Society of Civil Engineers
Abstract: The original NorSand (ONS) state-dilatancy law (ONS-SDL) presents challenges when trying to make changes in the formulation of the critical state line or stress–dilatancy rule and the associated yield surface. Additionally, ...
Uncertainty-Aware Linear Schedule Optimization: A Space-Time Constraint-Satisfaction Approach
Publisher: American Society of Civil Engineers
H2, Mixed H2/H∞ and H2/L1 Optimally Tuned Passive Isolators and Absorbers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In many practical applications, unbalanced rotating machinery cause vibrations that transmit large oscillatory forces to the system foundation. Using ad hoc optimization schemes tuned isolators and ...
