METHODS: The Micro-scale Audit of Pedestrian Streetscapes for Safe Routes to School (MAPS-SRTS) was developed from existing audit instruments not designed for school travel environments and modifications for the MAPS-SRTS instrument include the structure of the audit tool sections, the content, the observation route, and addition of new subscales. Subscales were analyzed for inter-rater reliability in a sample of 36 schools in Austin, TX. To assess reliability for each subscale, one-way random effects single-measure intraclass correlation coefficients (ICC) were used.
RESULTS: Compared to the 30 original subscales, the adapted MAPS-SRTS included 26 (86.6%) subscales with revised scoring algorithms. Most MAPS-SRTS subscales had acceptable inter-rater reliability, with an ICC of 0.97 for the revised audit tool.
CONCLUSIONS: The MAPS-SRTS audit tool is a reliable instrument for measuring the school travel environment for research and evaluation purposes, such as assessing human-scale determinants of active commuting to school behavior and documenting built environment changes from infrastructure interventions.
方法:从现有的审计工具中开发了用于学校安全路线的行人街景微观审计(MAPS-SRTS),这些工具不是为学校旅行环境设计的,并且对MAPS-SRTS工具的修改包括审计工具部分的结构,内容,观察路线,并增加了新的分量表。在奥斯汀的36所学校的样本中,对子表进行了评分者间可靠性分析,TX.为了评估每个子量表的可靠性,使用单向随机效应单测量组内相关系数(ICC).
结果:与30个原始分量表相比,经调整的MAPS-SRTS纳入了26个(86.6%)子量表,并采用了修订的评分算法.大多数MAPS-SRTS分量表具有可接受的评分者间可靠性,修订后的审计工具的ICC为0.97。
结论:MAPS-SRTS审核工具是用于测量学校旅行环境以进行研究和评估的可靠工具,例如评估主动通勤到学校行为的人类尺度决定因素,并记录基础设施干预带来的建筑环境变化。
