Two 4D Models Effective in Reducing False Alarms for Struck-by-Equipment Hazard Prevention

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 alarms (false positives and false negatives) are common in such systems, but methods for limiting struck-by hazards have not yet been thoroughly studied or tested for real-world implementations. This study presents two novel …
