The effect of ventilation system with and without under-platform exhaust on the concentration of braking micro-particles inside the subway system

, 2022
Thermal comfort has been the main target of the ventilation in subway systems. However, pollutant concen-tration and aerosol dispersion could be the leading health issues in underground metro stations.

Application of Sensor Networks to the Measurement of Subway-Induced Ground-Borne Vibration Near the Station

International Journal of Distributed Sensor Networks, 2014
The subway-induced ground-borne vibration poses great challenge to the environment in the nearby districts. This problem is more prominent for near-station sections of subways since more buildings and human activities are influenced.
