The invention discloses a traffic accident occurrence area prediction method and device. The method comprises the steps that a first traffic characteristic graph of a first area in a first time period is acquired, the first traffic characteristic graph is used for representing influence factors influencing traffic accidents in the first area, and the influence factors comprise at least one of the following factors: a vehicle movement track, weather, traffic flow, a road structure and a road image; determining a first feature matrix corresponding to the first traffic feature map; and performing prediction processing on the first feature matrix by using a pre-trained target traffic accident prediction model to obtain a first prediction sub-region in which the traffic accident occurs in the first region. According to the method and the device, the technical problem that the accuracy of a prediction result is relatively poor due to the fact that spatial heterogeneity and temporal heterogeneity among the sub-regions are not considered when the sub-regions in the region are predicted in the prior art is solved.

    本申请公开了一种交通事故发生区域预测方法、装置。其中,该方法包括:获取第一区域在第一时间段内的第一交通特征图,其中,第一交通特征图用于表征影响第一区域内发生交通事故的影响因素,且影响因素包括以下至少之一:车辆运动轨迹、天气、交通流量、道路结构、道路图像;确定第一交通特征图对应的第一特征矩阵;利用预训练的目标交通事故预测模型对第一特征矩阵进行预测处理,得到第一区域内发生交通事故的第一预测子区域。本申请解决了相关技术在预测区域内的子区域时,并未考虑各个子区域之间的空间异质性和时间异质性,导致预测结果准确性较差的技术问题。
