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. The advent of mobile phones, with their wide spatial/temporal coverage and ubiquitous presence in metro areas, offers a new source of data to conduct such studies. In this paper, the collision accident of Metro Line 10 in Shanghai, China on September 27, 2011 is carefully investigated based on data derived from mobile phone records. The evacuation process of the accident was studied, followed by an analysis of the influence of this accident on commuting in the city. After analyzing 7 billion of mobile phone records for a 10-day period, the authors find that the evacuation follows a two-stage pattern. The authors then identified the commuters of Line 10 and studied their commuting patterns in the day of accident and also in the subsequent days. The authors find that most of the Line 10 commuters still chose 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.
