The use of traditional positioning technologies relies on the underlying infrastructures. However, for the subway environment, such positioning systems may not be available for the positioning tasks, such as the detection of the train arrivals for the passengers in the train. An alternative way is to exploit the contextual information available in the mobile devices of subway riders. To this en...

Subway systems worldwide transport more than 100 million people daily; therefore, air quality on station platforms and inside trains is an important urban air pollution issue. We examined the microbiological composition and abundance in space and time of bioaerosols collected in the Barcelona subway system during a cold period. Quantitative PCR was used to quantify total bacteria, Aspergillus f...

The safety of underground structure under seismic load is an important basis the normal operation rail transit system. Structural vulnerability assessment based on incremental dynamic analysis method can evaluate probability exceeding a certain limit state specific intensity in terms probability. In this paper, multi-storey subway station evaluated using method, and two-dimensional finite eleme...
