A Hybrid Neural Network for the Traffic Flow Prediction on the Premise of Missing Data

On the basis of a generative adversarial network (GAN) and a convolutional neural network (CNN), this work proposes an ER-GAN-CNN to forecast the traffic flow in the presence of missing data by improving GAN. Due to the occurrence of emergencies and the fault of the relevant equipment, the equipment for passenger flow detection may lose some data, which would have negative impacts on passenger flow prediction. In order to cope with such situations, GAN is introduced to make up for the missing data in this paper. On the basis of complete data and CNN, inception blocks are built thereafter to further predict the passenger flow/traffic flow. The accuracy of the prediction of passenger flow is significantly improved with the help of the ER-GAN-CNN, which is able to provide more accurate and rapid traffic guidance for the drivers.
