As a result of the physical quantity measurements in subway stations, high relative humidity in the summer and low air temperatures were recorded. The concentration of particulate matters (PM) and the carbon dioxide satisfied the indoor air quality maintenance criteria for subway stations in South Korea. As a result of the comfort evaluations, most of respondents felt 'neutral' or 'comfortable' for environment in subway stations and there were gender and age differences on the comfort evaluations.
