Traffic flow prediction in spatio-temporal networks is a crucial aspect of Intelligent Transportation Systems (ITS). Existing traffic forecasting methods, particularly those utilizing graph neural networks, encounter limitations. When processing large-scale data, the depth these models can restrict their ability to effectively capture complex relationships and patterns. Additionally, methods often focus mainly on local neighborhood information, which limit capability recognize analyze global...

The predictive cruise control (PCC) is a promising method to optimize energy consumption of vehicles, especially the heavy-duty vehicles (HDV). Due limited sensing range and computational capabilities available on-board, conventional PCC system can only obtain sub-optimal speed trajectory based on shorter prediction horizon. recently emerging information communication technologies such as vehicular communication, cloud computing, Internet Things provide huge potentials improve traditional...
