The invention provides a method and system for predicting road traffic flow, the method uses a road traffic flow simulation model to predict the road traffic flow, the road traffic flow simulation model comprises multiple attention layers and a space-time processing layer based on LSTM, the multiple attention layers are used for integrating hidden layer state information of other road sections in space, and the multiple attention layers are used for integrating hidden layer state information of other road sections. The LSTM-based time-space processing layer is used for effectively understanding the time-space state of the current traffic flow so as to accurately reflect the traffic state in the current space. By using the method and the system provided by the invention, the traffic flow change can be accurately predicted.

    本发明提供了一种预测道路交通流量的方法和系统,该方法利用道路交通流量仿真模型预测道路交通流量,道路交通流量仿真模型包括多头注意力层和基于LSTM的时空处理层,其中多头注意力层用于整合空间上其他路段的隐层状态信息,基于LSTM的时空处理层用于有效的理解当前交通流的时空间状态以准确地反映出目前空间上的交通状态。通过使用本发明的方法和系统能够对交通流变化做出准确预测。
