... Regarding the particular techniques exploited for traffic prediction, Tab. 1 highlights a rising utilization of DL models, also in a multitask configuration [9,11,22]. Particularly, related works mostly employ CNN of different dimensions [9,15], LSTM [9,15,17,18,19,21,23], GRU [9,17,23], SAE [13], GNN [24], and hybrid architectures obtained via their combinations [9,15,20]. Fewer works leverage Markov models (e.g., MC, HMM, and MMG) [11,14,16,22], traditional ML models (e.g., LR, SVR, k-NNR, or RFR) [9,16,18,22], and statistical techniques (e.g., ARIMA or FARIMA) [12,15,17,18], usually as performance baselines to evaluate DL models, with the latter commonly showing better prediction performance. ...
