The invention discloses an expressway flow prediction method and system. The method comprises the following steps: obtaining traffic historical data of different vehicle types on different lanes; performing model training based on an LSTM model according to the historical data to obtain an LSTM prediction model; and the LSTM prediction model is used for prediction and a predicted traffic flow is obtained. According to the method, the LSTM model is trained through historical data, then subsequent prediction is carried out based on the prediction function of the LSTM model, good adaptability is achieved, finally, the simulation accuracy of the traffic flow on the toll station of the expressway is high, and good reference is achieved.

    一种高速公路流量预测方法及系统,包括如下步骤:获取不同车道上不同车型的通行历史数据;根据该历史数据基于LSTM模型进行模型训练得到LSTM预测模型;将LSTM预测模型用于预测并得到预测车流。本申请通过历史数据训练LSTM模型,然后基于其自身所具有的预测功能来进行后续预测,具有较好的适应性,最终对于高速公路的收费站上的车流量的模拟准确性较高,具有较好的参考性。
