Abstract

A wind tunnel experiment was conducted in order to study the effects of train-generated drafts on human postural stability. In the experiment, 29 people were exposed to a transient wind force similar to a draft from a passing train, and the results suggested that both wind speed and wind duration affect postural stability. In this paper, we estimated the tolerance of postural stability against transient wind based on a statistical model and a physical model, and discussed the validity of these models.
