The management of particulate matters (PM) concentration is very important in managing indoor air quality of subway stations. In this study, the effect of track type and nearby road traffic was investigated. PM concentration of subway stations with concrete only track was lower than that of stations with some ballast track. Among the subway stations with ballast track, PM concentration was higher at the stations with smaller portion of ballast track. PM concentration of outdoor air was proportional to the amount of road traffic. However, any direct relationships between traffic and PM concentration of subway stations was not observed.
