The invention belongs to the technical field of traffic flow prediction, and particularly relates to an event-oriented traffic flow prediction method and device. The method comprises the steps of firstly obtaining reference traffic flow data and target historical traffic flow in traffic flow data related to a trigger event, taking data of historical traffic flow in a preset time as reference data, then obtaining the target historical traffic flow according to a target event type, and obtaining the target historical traffic flow according to the target historical traffic flow. And finally, the increase and decrease value of the historical flow and the target historical flow is obtained, and a prediction result is obtained. According to the method, the prediction coverage range and the prediction accuracy are expanded, low accuracy possibly brought by a single prediction method is avoided, meanwhile, the vehicle flow increase and decrease value is calculated by calculating the total vehicle flow and the standard deviation in the confidence interval and selecting the similar vehicle flow increase and decrease interval, and the accuracy of the vehicle flow increase and decrease value is improved.
本发明属于交通流量预测技术领域,具体的说是涉及一种面向事件的交通流量预测方法和装置。本发明的方法是先获取触发事件相关的交通流量数据中参考交通流量数据、目标历史车流量,将处于预设时间内的历史车流量的数据作为参考数据,然后根据目标事件类型,获得目标历史车流量,从而计算出与采集时刻内的车流量的标准差,最后获得历史流量与目标历史流量的增减值,获得预测结果。本发明扩大了预测的覆盖范围和预测的准确性,避免了单一预测方法可能带来的较低的准确性,同时通过计算置信区间内的总车流量和标准差,选取相似的车流量增减区间来计算车流量增减值,提高了车流量增减值的准确性。
