The purposes of this study were to provide an update to the ambulatory distance requirements for community ambulation and to update gait speed performance and requirements at intersections.
Distances were measured at 9 types of sites using a rolling measuring device in accordance with the protocol set forth by Lerner-Frankiel and associates. The 9 types of sites were supermarkets, drug stores, banks, department stores, post offices, medical offices, superstores, club warehouses, and hardware stores. Gait speed allotted by crosswalk signals as well as the gait speeds of individuals through crosswalks were recorded. Qualitative observations of the pedestrians' age (older - 65 years; younger < 65 years) and sex were also noted.
Distances were measured at 141 different establishments. The shortest mean distance requirement was found in the medical offices at 65.82 (32.28) m. Club warehouses had the longest mean distance requirement at 676.82 (159.36) m. The mean gait speed used by the pedestrians (N = 139) was 1.32 (0.31) m/s while the mean speed necessary as set by the crosswalk signals was 0.49 (0.20) m/s. All of the individuals observed were able to cross the street within the allotted time and with adequate speed. The gait speeds met the normative data established for age and sex as well as data reported for slower older adults and some with incomplete spinal cord injury.
Distance requirements for full community ambulation may need to be increased to 600 m or more. Gait speed requirements at crosswalks in the communities measured are set to accommodate the gait speed capabilities of older pedestrians who attempt crossing at controlled intersections.
本研究旨在更新社区步行的非卧床距离要求，并更新十字路口的步态速度表现和要求。
使用滚动测量设备，按照 Lerner-Frankiel 及其同事制定的方案，在 9 种类型的场所测量距离。这 9 种类型的场所包括超市、药店、银行、百货公司、邮局、医疗办公室、大型超市、俱乐部仓库和五金店。记录了行人通过横道信号的规定的步态速度以及穿过横道的个人的步态速度。还对行人的年龄（65 岁以上；65 岁以下）和性别进行了定性观察。
在 141 个不同的场所测量了距离。最短的平均距离要求在医疗办公室为 65.82（32.28）m。俱乐部仓库的平均距离要求最长，为 676.82（159.36）m。（N = 139）行人使用的平均步速为 1.32（0.31）m/s，而横道信号规定的平均速度为 0.49（0.20）m/s。观察到的所有个体都能够在规定的时间内以足够的速度穿过街道。步态速度符合为年龄和性别制定的规范数据，以及为速度较慢的老年人和一些不完全性脊髓损伤患者报告的数据。
完全社区步行的距离要求可能需要增加到 600 米或更长。在社区测量的横道处的步态速度要求是为了适应试图在受控交叉口穿越的老年行人的步态速度能力。
