基于防范目标导向的居民区光环境现状调查与分析

摘要

A method of Kendall's rank correlation was proposed to investigate and analyze the current situation of the light environment prevention based on goal orientation.The status of light environment prevention based on object oriented was investigated using subjective and objective methods in residential district of Dalian city,then the Kendall's method was used to analyze the survey results of rank correlation.It indicated that there was a significant correlation among the sense of safety and road pavement,the degree of light and dark,clarity of pedestrian recognition difficulty and face deviation degree.It could provide a feasible way to build a safe residential area light environment in the future.%为实现对于基于目标导向的防范光环境现状进行调查与分析,提出一种Kendall,s等级相关的方法分析.该方法首先以大连市居民区为调查对象采用主客观结合的方法对于基于目标导向的防范光环境现状进行调查,然后用Kendall's等级相关的方法分析调查结果,得出安全感与路面亮暗程度、路面清晰度、识别行人难易度和面目表情偏差程度有显著相关性.实验证明该方法简单有效,为以后建设安全的居民区光环境提供了可行的思路.
