The invention provides a traffic flow prediction method and device and a storage medium, and the method comprises the steps: importing a historical traffic flow data set which comprises a time slice data set and an additional factor data set; inputting the time slice data set into an encoder, and performing feature extraction on the time slice data set through the encoder to obtain a plurality of original short-term time feature implicit state vectors and a plurality of long-term time feature implicit state vectors; and inputting the additional factor data set, the plurality of original short-term time feature hidden state vectors and the plurality of long-term periodic time feature hidden state vectors into a decoder together, and performing prediction value analysis to obtain a traffic flow prediction result. According to the method, the time dependence relationship between the traffic flows is obtained, so that accurate real-time traffic flow prediction is realized, and the method has interpretability.

    本发明提供一种交通流预测方法、装置及存储介质,方法包括:导入历史交通流量数据集,历史交通流量数据集包括时间片数据集和额外因素数据集;将时间片数据集输入至编码器中,通过编码器对时间片数据集进行特征提取,得到多个原始短期时间特征隐状态向量和多个长期时间特征隐状态向量;将额外因素数据集、多个原始短期时间特征隐状态向量和多个长期周期性时间特征隐状态向量一并输入解码器中,进行预测值分析,得到交通流预测结果。本发明获取了交通流间的时间依赖关系,从而实现了准确的实时交通流量预测,而且具有可解释性。
