dc.description.abstract | Monitoring workers' exposures to slip, trip, and fall (STF) hazards is critical to preventing STFs at construction sites. This study developed a model to assess workers' exposures to STF hazards by predicting abnormal gait patterns from a series of steps. The model was then evaluated and validated through a field experiment. Gait variability features were extracted from a waist-worn inertial measurement unit (IMU) and converted into Mahalanobis distance. Bidirectional long short-term memory models were used to predict abnormal gait patterns using confidence interval estimation. The model generated an Unweighted Average Recall (UAR) of 93.0% (normal walking: 93.0% and exposure to STF hazards: 93.0%), which demonstrates that workers' exposures to STF hazards can be continuously and remotely monitored, potentially helping to prevent STFs on construction worksites. | - |
