Construction Safety Hazard Detection Through Continuous Monitoring of Construction Workers’ Behavior Using Wearable Wireless Sensor Networks
The goal of this research is thus to provide a continuous and reliable assessment of safety hazards by exploring the application of low-cost wireless sensor networks (WSNs), consisting of wearable inertial measurement units (IMU) and wireless data communication devices, in monitoring construction workers’ behaviors.
Automated Recognition of Construction Equipment Driving Events using a Smartphone as a Multi-sensor Hub
This research, in particular, focuses on the analysis of data from inertial measurement units (IMU) (e.g., three-axis accelerometer, gyroscope, magnetometer) embedded in a smartphone, and leverages the effectiveness of the driving event recognition by data fusion with other sensing information from the smartphone (e.g., GPS, cellular data network, video cameras).
An Integrated Framework for Estimating, Benchmarking and Monitoring the Environmental Impacts of Construction Operations.
This research aims to establish an integrated management framework that encompasses environmentally conscious planning and environmental performance monitoring in order to facilitate environmentally sustainable construction practices.
