Xiaoqing Dai, Han Qiu, Lijun Sun
2021 Sustainability  
Then, based on these mathematical expressions, we develop a simulation system to imitate the spatio-temporal evolution of evacuation demand within the whole network under disruptions.  ...  One general observation we draw from the results is that the most vulnerable stations under disruption, where the locations peak evacuation demand occurs, are mainly turn-back stations, closed stations  ...  Evacuation demand prediction under disruptions can support both proactive emergency plan design and real-time emergency response.  ...
