The invention discloses an urban rail transit short-time OD demand prediction method under emergencies. The method comprises the following steps: in a current time period t, obtaining an observed OD demand sequence, real-time pull-in flow data and a rail transit network diagram; and inputting the OD demand sequence, the real-time pull-in flow data and the rail transit network diagram into a trained prediction model, and predicting the OD demand of the rail transit system in the next time period. According to the method, weekly and daily OD demand modes can be effectively integrated to capture long and short time historical OD distribution information, and the prediction precision of the OD demand under an emergency is improved while the real-time requirement of short time OD demand prediction is met.

    本发明公开了一种突发事件下的城市轨道交通短时OD需求预测方法。该方法包括:在当前时间段t,获取观测到的OD需求序列、实时进站流数据和轨道交通网络图;将所述OD需求序列、所述实时进站流数据和所述轨道交通网络图输入到经训练的预测模型,预测下一个时间段的轨道交通系统的OD需求。本发明能够有效整合周时和日时OD需求模式,以捕捉长短时历史OD分布信息,在满足短时OD需求预测实时性要求的同时,提高了突发事件下OD需求的预测精度。
