Understanding Evacuation and Impact of a Metro Collision on Ridership Using Large-scale Mobile Phone Data

- - posted in project

As randomly occurring events, traffic accidents pose serious challenges to the collection of comprehensive data to understand how travelers respond to them and to quantify their impacts. In this work, anonymous mobile phone data is used to investigate the collision accident of Metro Line 10 in Shanghai, China on 27 September 2011. The evacuation process of the accident is studied, followed by an analysis of the impact of this accident on commuting in the city. It is found that most of Line 10 commuters still preferred to use metro to complete their travels during the disruption period of Line 10, and returned to their typical commuting patterns immediately after Line 10 resumed service.
