Analysis of Spot Cooling in an Underground Subway Station

International Journal of Ventilation, 2004
AbstractRailway platform spot cooling has become an increasingly attractive means to improve thermal comfort conditions of existing subway stations. This paper presents a systematic approach to evaluate the effectiveness of platform spot cooling. The subway environment is first analysed by a simple one-dimensional network model, which is able to ...

A review on characteristics and mitigation strategies of indoor air quality in underground subway stations

Science of The Total Environment, 2023
Due to the rapidly increasing ridership and the relatively enclosed underground space, the indoor air quality (IAQ) in underground subway stations (USSs) has attracted more public attention. The air pollutants in USSs, such as particulate matter (PM), CO2 and volatile organic compounds (VOCs), are hazardous to the health of passengers and staves ...

A Spatial Analysis of Underground Public Pedestrian Facilities Connected to Subway Station - Focused on the Underground Shopping Arcade around the Subway Stations in Gyeongin Line -

Crisis and Emergency Management: Theory and Praxis, 2018
Underground public pedestrian facilities were mainly built throughout the 1970s to 1980s. These facilities have been used as an evacuation area in case of emergency and a convenient access road to underground level. Underground shopping arcades were installed to reduce the construction costs and create more available space. However, during this process,

Commuter exposure to particulate matter at underground subway stations in Philadelphia

Building and Environment, 2020
Abstract We present the first report of exposure to particulate matter by commuters at 12 underground subway stations in Philadelphia, Pennsylvania, USA. Particle measurements were taken during two springtime periods: March 4 to 9, 2018 and February 1 to April 12, 2019. Particle concentrations were variable across the subway stations and demonstrated

Underground air quality monitoring in subway stations in Bucharest city

AIP Conference Proceedings, 2020
As a result of the urban development in the cities, the underground transport has become a priority transit route used by the population, due to the fact that it is a faster route and also due to the need to reduce the road traffic from the surface in order to improve the quality of the air (especially degraded from traffic emissions).

BIM Technology Used in Underground Subway Station Planning Simulation

Applied Mechanics and Materials, 2014
This paper studied the underground subway station planning depend on BIM technology. The existing 3D buildings’ information was processed by computer technology. Using the information and planning based on constraints on the space station, the simulation of the actual situation in 3D view way constantly, adjust planning position, compare each project ...

Acoustical design for public address announcements in an underground subway station

Noise Control Engineering Journal, 2014
The public address (PA) is a part of the passenger information system in an underground subway station. A sample station named Xingzhong Road on metro line 9 in Shanghai is considered in this paper. A ray-tracing model for acoustical simulation of the PA system is established.

Seismic performance and effective isolation of a large multilayered underground subway station

Soil Dynamics and Earthquake Engineering, 2021
Abstract In this paper, the seismic performance of a reinforced concrete (RC)-framed underground subway station structure which has three stories and three spans was analyzed firstly under strong earthquakes. It was found that the central columns in the top and the bottom stories were the weakest seismic components in this type of underground ...

Experimental and Numerical Investigation of Bypass Tunnel on Piston Effect of Underground Subway Station

Proceedings of the 6th International Conference on Informatics, Environment, Energy and Applications, 2017
With the rapid growth of the infrastructure constructions in China, more and more metro lines have been built in recent years. The piston wind have a significant influence on the air temperature and the flow field of subway stations and tunnels. The bypass wind tunnel located on both side of the platform, which have great effect of shunt piston wind ...
