Abstract To reduce passenger waiting time and driver search friction, ride‐hailing companies need to accurately forecast spatio‐temporal demand and supply‐demand gap. However, due to spatio‐temporal dependencies pertaining to demand and supply‐demand gap in a ride‐hailing system, making accurate forecasts for both demand and supply‐demand gap is a difficult task. Furthermore, due to confidentiality and privacy issues, ride‐hailing data are sometimes released to the researchers by removing spatial adjacency information of the zones, which hinders the detection of spatio‐temporal dependencies. To that end, a novel spatio‐temporal deep learning architecture is proposed in this paper for forecasting demand and supply‐demand gap in a ride‐hailing system with anonymised spatial adjacency information, which integrates feature importance layer with a spatio‐temporal deep learning architecture containing 1D convolutional neural network (CNN) and zone‐distributed independently recurrent neural network (IndRNN). The developed architecture is tested with real‐world datasets of Didi Chuxing, which shows that the models based on the proposed architecture can outperform conventional time‐series models (e.g. ARIMA) and machine learning models (e.g. gradient boosting machine, distributed random forest, generalized linear model, artificial neural network). Additionally, the feature importance layer provides an interpretation of the model by revealing the contribution of the input features utilized in prediction.
