The invention discloses a data processing method, a related device, equipment and a storage medium, which can be applied to the field of traffic. The method comprises the following steps: acquiring M * N space-time slices of a to-be-analyzed region; obtaining vehicle positioning data, event reporting data and influence factor data of each time-space slice; determining an event occurrence characterization value according to the vehicle positioning data and the event reporting data of each time-space slice; based on the influence factor data of each time-space slice, obtaining an event occurrence prediction value through a factor prediction model; according to the event occurrence prediction value and the event occurrence characterization value of each time-space slice, the conditional probability of connecting edges between nodes in the factor prediction model is updated; and determining K influence factors according to the updated factor prediction model. According to the method, the causal association relationship among the influence factors is explained through the factor prediction model, and the target influence factor for the target event is mined, so that strong dependence on accident record data is effectively avoided.
本申请公开了一种数据处理的方法、相关装置、设备以及存储介质,可应用于交通领域。本申请包括:获取待分析区域的M×N个时空切片;获取每个时空切片的车辆定位数据、事件上报数据和影响因素数据;根据每个时空切片的车辆定位数据和事件上报数据确定事件发生表征值;基于每个时空切片的影响因素数据,通过因素预测模型获取事件发生预测值;根据每个时空切片的事件发生预测值和事件发生表征值,对因素预测模型中节点之间连边的条件概率进行更新;根据更新后的因素预测模型确定K个影响因素。本申请通过因素预测模型解释各个影响因素之间的因果关联关系,挖掘出针对目标事件的目标影响因素,从而有效地避免了对事故记录数据的强依赖。
