A deep learning model that uses spatio-temporal periodic patterns to forecast crowd density way ahead of time
In the normal Spatio-temporal forecasting, the models used often do not explicitly considered periodic patterns. Our proposed Periodic-Convolutional Recurrent Network (PCRN) is the first deep learning based model that uses periodic patterns in a CRN architecture for accurate spatio-temporal forecasting.
PCRN outperforms commonly used models ARIMA, ST-ResNet (deep learning) model and 4 other baselines consistently with the lowest error rate in the prediction of crowd density.
In the Multi-step Ahead prediction for predicting the next 6 steps ahead, PCRN shows the lowest rate of error increase as compared with the other 6 baselines.
This model could be utilized to assist in optimising traffic management and crowd control more accurately.
