A method to collect the times and travel routes in predefined sections of stairs is presented, in order to obtain walking velocities of children. Twenty‐seven possible travel paths on landings and nine possible travel paths on flights are proposed and the equations developed to calculate them are presented. Experiments were carried out where data were not collected from fire drills, as usually are, but from the movement of unimpeded individuals descending stairs using this method. The technique used to collect data was the observation of video recordings via a closed‐circuit television system. Seven hundred and eighty‐three students ranging from 6 to 10 years of age and from three different schools participated in the experiments. Particularly, movements on stair flights and landings were analyzed separately for a group of 54 students of the first grade (6 years‐old), for a comparative analysis of the distances and velocities obtained with methods used by other researchers and significant differences were found. In addition, by the present method, the dispersion of velocity values in a population was studied; thus, the shape of its frequency distribution could be verified. An uncertainty estimative of the method is presented together with the discussion of its usage difficulties.

在学校上楼梯儿童下坡运动的数据收集方法

为了获得儿童的步行速度，提出了一种在楼梯的预定部分中收集时间和行进路线的方法。提出了在着陆点上的27条可能的行进路径和在航班上的9条可能的行进路径，并提出了计算它们的方程。进行实验时，不是像平常那样从消防演习中收集数据，而是从使用此方法从下楼梯的无障碍人员的移动中收集数据。收集数据的技术是通过闭路电视系统观察录像。来自三所不同学校的783名年龄在6至10岁之间的学生参加了实验。特别，分别对一组54名一年级（6岁）学生的楼梯飞行和着陆运动进行了分析，以比较分析其他研究人员使用的方法获得的距离和速度，发现存在显着差异。另外，通过本方法，研究了速度值在总体中的分散性；因此，可以验证其频率分布的形状。提出了该方法的不确定性估计，并讨论了其使用困难。可以验证其频率分布的形状。提出了该方法的不确定性估计，并讨论了其使用困难。可以验证其频率分布的形状。提出了该方法的不确定性估计，并讨论了其使用困难。
