Urban Rail Train Operation Scheduling Under Emergency Conditions

摘要

In the event of natural disasters and other modes of transport failures, resulting in a sudden surging passenger flow in transportation hub, aimed at the minimum of passenger evacuation time and the lowest cost of the operating company, the combination of minimization model is established, the operating frequency, the length of train classification, the configuration number and the full load rate taken as constraints. In the model, the weights of the two optimization targets are coordinated by the decision-maker's intention to get more benefiting results. The Nanjing Metro Line 1 is taken as an example to get train operating frequency and the urban rail train operation schedule under emergency conditions is worked out. The results show that the model designed in this paper can satisfy the need of passenger evacuation under emergency conditions.
