RTSC presents big data research to President Xi Jinping

Chinese President Xi Jinping visited Imperial College London on the 21st October. As a result of a collaboration between the RTSC, Shanghai Metro, and the Data Science Institute (DSI) of Imperial, the Presidential visit included a presentation on the analysis of smartcard data for the Shanghai Metro network.

Our main research objective was to improve our understanding of demand patterns captured in smartcard data. We visualised passenger flows entering and exiting Shanghai metro stations using the extraordinary visualisation capabilities of the KPMG Data Observatory of DSI. The Data Observatory is the largest of its kind in Europe, featuring an enveloping circular wall of 64 monitors powered by 32 computers facilitating 313 degrees of surround vision.

In the second part of the presentation we visualised a simulation scenario for a hypothetical train service disruption. This allowed us to predict how temporary demand shocks would spread through other parts of the network. Studying disruption scenarios enables operators to prepare for unexpected events and improve the resilience of urban rail networks.

The Presidential visit proved to be an excellent opportunity to showcase the RTSC’s recently developed competences in big data analysis, and the potential of smart card data in cutting edge public transport research.
