The invention provides a method and device for identifying and repairing abnormal data of time sequence traffic flow, and relates to the technical field of data processing.The method comprises the steps that firstly, the abnormal data are identified from a traffic flow data set based on the traffic flow theory, the time continuity of traffic flow data and the time distribution characteristic of motor vehicle flow; the method comprises the steps of obtaining an initial traffic flow abnormal data set, then correcting the initial traffic flow abnormal data set by combining all traffic event information influencing traffic in a specified time period to obtain a target traffic flow abnormal data set, and finally repairing the motor vehicle flow in the target traffic flow abnormal data by using historical traffic flow data. The method is based on a traffic flow theory and road network traffic flow characteristics, and utilizes potential rules and association in traffic flow data to realize identification and restoration of traffic flow abnormal data, thereby providing complete and accurate data support for road network flow traffic prediction, traffic management, traffic induction and the like.
本发明提供了一种时序交通流的异常数据识别与修复的方法和装置,涉及数据处理的技术领域,该方法首先基于交通流理论、交通流数据的时间连续性和机动车流量的时间分布特征从交通流数据的集合中识别异常数据,得到初始交通流异常数据集合,然后结合指定时间段内影响交通的所有交通事件信息对初始交通流异常数据集合进行校正,得到目标交通流异常数据集合,最后利用历史交通流数据对目标交通流异常数据中的机动车流量进行修复。该方法基于交通流理论和路网交通流特征,利用交通流数据内部潜在规律与关联,实现了交通流异常数据的识别与修复,为路网流量交通预测、交通管理、交通诱导等提供完备、准确的数据支撑。
