地铁乘客夏季热感觉影响因素的双变量相关分析

Bivariate correlation analysis of influencing factors of metro passenger thermal sensation in summer

在问卷调查和现场测试的基础上,运用双变量相关分析法分析了地铁乘客夏季热感觉投票值与各影响因素之间的直线相关性.结果表明,各因素与影响乘客热感觉相关性按显著程度的排序为:温度>相对湿度>性别>乘坐频率>年龄层>单程乘坐时长>乘坐状态>服装热阻.温湿度仍然是影响乘客热感觉的主要因素,同时性别和乘坐频率也与乘客热感觉显著相关,水平为0.05(双侧).结合问卷情况对典型因素进行了分析.

Based on a questionnaire and field test, correlation between thermal sensation vote of metro passenger in summer and its influencing factors is analyzed by bivariate correlation.By the analysis result, factors are sorted in the correlation significance’ s descending order, and they are temperature,relative humidity, gender,ride frequency, age,oneway time, ride condition and clothing. Temperature and relative humidity are still the main factors that influence the thermal sensation, besides, therere two factors also show correlation signifi-cant at 0. 05 level, gender and ride frequency. Typical factors are analyzed according to the questionnaire.
