基于语境特征注入的交通流速度预测模型
Traffic flow speed prediction based on context feature injection and fusion
摘要
Abstract
A traffic flow speed prediction model based on context feature injection is proposed.The time series features and context features of traffic flow speed data are learned and extracted through recurrent neural networks and deep belief networks,respectively.The vector fusion mechanism is used to inject the extracted context features into the time series features to generate new fusion features,which are used for traffic flow speed prediction.The experimental results show that the proposed model can reflect the real state of the traffic flow speed and accurately capture the stochastic changes of traffic speed,and has good predic-tive performance.On six time scales,such as 5 min and 10 min,the prediction error of the model is better than that of other comparison models.关键词
