The invention discloses a traffic flow prediction method and device, computer equipment and a storage medium, and the method comprises the steps: constructing a real urban traffic road scene through employing a digital twin simulation platform, and carrying out the collection of twin traffic data; the twinborn traffic data and the real traffic data form a mixed data set containing twinborn traffic data and real traffic data according to a mixing proportion alpha, and then multi-time-dimension fusion is carried out to obtain a first fusion feature; performing feature extraction based on the weather data and the traffic light information to obtain weather features and traffic information features; performing feature fusion on the first fusion feature, the weather feature and the traffic information feature to obtain a second fusion feature; and performing traffic prediction according to the second fusion feature to obtain a traffic prediction result. According to the invention, the accuracy of traffic flow prediction in a complex environment is improved.

    本发明公开了一种交通流量预测方法、装置、计算机设备及存储介质,包括:采用数字孪生仿真平台构建真实的城市交通道路场景,并进行孪生交通数据收集;对孪生交通数据和真实交通数据以混合比例α形成一个包含孪生和真实的混合数据集,再进行多时间维度融合,得到第一融合特征;分别基于天气数据和交通灯信息进行特征提取,得到天气特征和交通信息特征;对第一融合特征、天气特征和交通信息特征进行特征融合,得到第二融合特征;根据第二融合特征进行流量预测,得到流量预测结果。采用本发明提高了复杂环境下交通流量预测的准确性。
