The invention discloses a traffic scheduling method and device, and the method comprises the following steps: S1, inputting traffic flow data, and extracting the global spatial features and local spatial features of the traffic flow data through a multi-graph convolution module based on a graph self-attention mechanism; s2, fusing the global spatial features and the local spatial features; s3, inputting the fused spatial features into a time sequence prediction module, and outputting a traffic flow prediction result; s4, formulating a scheduling strategy according to the traffic flow prediction result; according to the method, extraction of global spatial features and extraction of local spatial features can be taken into consideration through the multi-graph convolution module, a receptive field of a time dimension can be increased through the time sequence prediction module, interaction between the spatial features and time sequence features can be improved, the traffic flow prediction precision is effectively improved, and then a traffic scheduling strategy is optimized.

    本发明公开了一种交通调度方法与设备,包括如下步骤:S1、输入交通流数据,并使用基于图自注意力机制的多图卷积模块提取交通流数据的全局空间特征和局部空间特征;S2、融合所述全局空间特征和局部空间特征;S3、将所述融合后的空间特征输入时序预测模块,输出交通流预测结果;S4、根据所述交通流预测结果制定调度策略;本发明能够实现通过多图卷积模块兼顾全局空间特征的提取和局部空间特征的提取,能够实现通过时序预测模块增加时间维度的感受野并提升空间特征和时序特征的交互,从而有效提升交通流预测精度,进而优化交通调度策略。
