有缺陷的人行道阻碍了街道的步行，还可能导致行人的安全事故(滑倒、绊倒和跌倒)。当行人在人行道上行走时，他/她的行为可能会根据人行道的状况而有所不同-例如，路面是正常的、有洞的、有裂缝的、倾斜的还是倾斜的。因此，行人的稳定性也可能会随着建筑环境的条件而变化。因此，本文研究了利用行人的物理行为来检测人行道缺陷的可行性。利用惯性测量单元(IMU)传感器和全球定位系统(GPS)收集行人在人行道上的物理反应和路径。然后，在对行人的身体反应和位置进行汇总后，计算出多个行人的反应相对于其位置的不规则性。行人反应模式中显示不规则的位置与缺陷的存在呈现出高度的相关性。本研究的结果将有助于提高对人行道缺陷的连续诊断，从而提高这些建筑环境系统的适用性。(C)2016爱思唯尔有限公司。保留所有权利。
A defective sidewalk inhibits the walkability of a street and may also cause safety accidents (slips, trips, and falls) for pedestrians. When a pedestrian walks along a sidewalk, his/her behaviors may vary according to the condition of the sidewalk-e.g., whether the surface is normal, holed, cracked, tilted, or sloped. As a result, the pedestrian's stability may also change according to the built environment's conditions. Accordingly, this paper examines the feasibility of using pedestrians' physical behaviors to detect defects in a sidewalk. Pedestrians' physical responses and paths over a sidewalk are collected using an inertial measurement unit (IMU) sensor and a global positioning system (GPS). Then, after aggregating the pedestrians' bodily responses and locations, the irregularity of multiple pedestrians' responses are calculated in relation to their locations. The locations that show irregularities in the pedestrian-response patterns present a high correlation with the existence of a defect. The results of this study will help improve the continuous diagnosis of defects in sidewalks, thereby enhancing these built environment systems' serviceability. (C) 2016 Elsevier Ltd.
