The invention discloses a traffic safety early warning system and method for an expressway. The method comprises the following steps: firstly, acquiring a real-time expressway road image of a road section to be analyzed, which is acquired by an unmanned aerial vehicle, then, carrying out data preprocessing on the real-time expressway road image to obtain a sequence of real-time expressway road image blocks; secondly, extracting local real-time road state features of the sequence of the real-time road image blocks of the expressway to obtain a sequence of a real-time road state feature matrix of the expressway; and extracting road state association features between the road sections among the sequences of the highway real-time road state feature matrix to obtain a highway road state association feature map, and finally, determining whether to generate highway traffic safety early warning based on the highway road state association feature map. Therefore, whether the highway traffic safety early warning needs to be generated or not can be automatically judged.

    公开了一种用于高速公路的交通安全预警系统及方法。其首先获取由无人机采集的待分析道路路段的高速公路实时道路图像,接着,将所述高速公路实时道路图像进行数据预处理以得到高速公路实时道路图像块的序列,然后,提取所述高速公路实时道路图像块的序列的局部实时道路状态特征以得到高速公路实时道路状态特征矩阵的序列,接着,提取所述高速公路实时道路状态特征矩阵的序列之间的路段间道路状态关联特征以得到高速公路路段间道路状态关联特征图,最后,基于所述高速公路路段间道路状态关联特征图,确定是否生成高速公路交通安全预警。这样,可以自动化地判断是否需要生成高速公路交通安全预警。
