The invention provides a traffic track flow type big data real-time processing method. The method comprises steps of obtaining N kinds of source data collected in a first time period; performing trajectory modeling of each time coordinate data sequence in the first M kinds of source data to obtain a corresponding trajectory model; according to the track model corresponding to each time coordinatedata sequence in the ith kind of source data and each time coordinate data sequence in the jth kind of source data, respectively calculating a difference index; determining a temporary association relationship between the time coordinate data sequence in the ith source data and the time coordinate data sequence in the jth source data according to the difference index; and determining a time coordinate data sequence representing the same target moving track in all the source data according to the temporary association relationship. The method provided by the invention is advantaged in that under the condition that the time coordinate data sequences of the targets in different source data cannot be directly associated through the existing information, the time coordinate data sequence representing the same target moving track can be determined.

    本说明书提供一种交通轨迹流式大数据实时处理方法,包括:获取第一时间段内采集的N种源数据;对前M种源数据中的各个时间坐标数据序列进行轨迹建模,得到对应的轨迹模型;根据第i种源数据中各个时间坐标数据序列对应的轨迹模型和第j种源数据中各个时间坐标数据序列,分别计算差异度指标;根据差异度指标确定第i种源数据中的时间坐标数据序列与第j种源数据中的时间坐标数据序列间临时关联关系;根据临时关联关系确定所有源数据中表示同一目标运行轨迹的时间坐标数据序列。本说明书提供的方法,在无法通过已有的信息将不同源数据中的目标的时间坐标数据序列进行直接关联的情况下,可以确定表示同一目标运行轨迹的时间坐标数据序列。
