It appeared that the thermal environment in concourse isclosely related to passengers comfort. As the result of surveys, it was clarified that thermalenvironment in the concourse was not acceptable enough for passengers. At most place andtime, thermal environment in concourse was easily over 32C in SET*, upper limit ofacceptable range for passengers. In addition, thermal environment in the concourse waswidely distributed. But passengers stayed in relatively uncomfortable place for the reasons ofmeeting people. For improving thermal environment and comfort in the station, it should beconsidered that the detail of thermal environment and occupancy characteristic of passengers.
