The paper has no problem there at all. Many prior papers have demonstrated that neural network models significantly outperform non-neural network models in transportation forecasting like https://arxiv.org/abs/1707.01926 https://arxiv.org/abs/1707.01926, http://www-scf.usc.edu/~yaguang/papers/aaai19_multi_graph_convolution.pdf http://www-scf.usc.edu/~yaguang/papers/aaai19_multi_graph_co... As this paper has chosen the state-of-the-art neural network models as baselines, it has already done enough and decent jobs on choosing baselines.
