Despite increased regulations, restrictive measures, and devices used for warnings, work zone injuries and fatalities are still observed at highway construction projects with alarms/notifications being ignored. With a vision to reduce the number of injuries and fatalities, Phase 2 of the research team's worker safety project extends the original scope and adds a Hardware in the Loop (HIL) component to simulate real traffic scenarios through simultaneous interactions with variety of vehicles and deployed sensor data in immersive virtual environments. The project aims to understand the key parameters (e.g., work zone location characteristics, personal vigilance levels, duration of construction work) that play roles in behaviors of workers in response to notifications received from various warning mechanisms (e.g., sound, vibration). Key questions this research answers are, at what conditions workers ignore/response to warnings at work zones? How we can calibrate notification systems for getting responsive actions from workers? What are the modalities, frequencies, and timings of pushing notifications in these calibrated systems? Through wearable sensors and hardware integrated realistic representations of work zones in virtual reality, the team plans to collect worker behavioral and physiological (heart rate) responses to alarms/warnings/notifications issued under various realistic scenarios and modalities of warning mechanisms (e.g., sensory, visual, audial) and analyze these captured data towards understanding human behaviors in response to modalities of notifications. |
