To explore the thermal environment and thermal comfort of five typical elevated subway stations in Wuhan during winter,this study obtained the physical environmental parameters of the stations through field measurements and calculated the Standard Effective Temperature(SET*)index.In conjunction with a thermal comfort survey of passengers,the neutral thermal temperature and comfortable thermal range for passengers were established,forming the basis for a thermal comfort evaluation model tailored for elevated subway stations in Wuhan during the winter season.The results indicate that the thermal environment of elevated stations in winter does not meet the requirements set forth in"Code for design of metro"(GB 50157-2013).The air temperature in the stations is excessively low,the relative humidity is severely affected by weather conditions,and some stations experience excessively high air velocities.By fitting SET*with Predicted Thermal Sensation(PTS),this study assessed the passengers'thermal adaptability in winter.Moreover,by tracking the environmental and physiological changes of passengers from entry to carriage,the Heat Deficit Rate(HDR)at various nodes of entry was calculated,revealing a significant correlation between passengers'cold adaptability and the architectural form of the stations.
