| Abstract: | With the high-speed development of urban rail transit,the target maximum train velocity has exceeded the velocity range specified in the current metro design codes.Some aerodynamic phenomena which could be ignored under the lower velocities have become very prominent under the high speed.This paper presents relative aerodynamic phenomena concerned with the blockage ratio and qualitatively analyzes some alleviation measures accounting for the specialties of subway. |

| Keywords: | urban rapid rail transit aerodynamics blockage ratio alleviation measures |
