Scalable Learning With a Structural Recurrent Neural Network for Short-Term Traffic Prediction

1 code implementation3 Mar 2021 Youngjoo Kim, Peng Wang, Lyudmila Mihaylova

With the real traffic speed data measured in the city of Santander, we demonstrate the proposed SRNN outperforms the image-based approaches using the capsule network (CapsNet) by 14. 1% and the convolutional neural network (CNN) by 5. 87%, respectively, in terms of root mean squared error (RMSE).
