Abstract
Walking-induced loads on office floors can generate unwanted vibrations. The current multiperson loading models are limited since they do not take into account nondeterministic factors
such as pacing rates, walking paths, obstacles in walking paths, busyness of floors, stride lengths,
and interactions among the occupants. This study ...
Walking-induced loads on office floors can generate unwanted vibrations. The current multiperson loading models are limited since they do not take into account nondeterministic factors
such as pacing rates, walking paths, obstacles in walking paths, busyness of floors, stride lengths,
and interactions among the occupants. This study proposes a novel video-vibration monitoring
system to investigate the complex human walking patterns on floors. The system is capable of
capturing occupant movements on the floor with cameras, and extracting walking trajectories
using image processing techniques. To demonstrate its capabilities, the system was installed on a
real office floor and resulting trajectories were statistically analyzed to identify the actual
walking patterns, paths, pacing rates, and busyness of the floor with respect to time. The
correlation between the vibration levels measured by the wireless sensors and the trajectories
extracted from the video recordings were also investigated. The results showed that the proposed
video-vibration monitoring system has strong potential to be used in training data-driven crowd
models, which can be used in future studies to generate realistic multi-person loading scenarios.
