Potential failures of physics-informed machine learning in traffic flow modeling: theoretical and experimental analysis
Low-resolution traffic detector data, not the MLP's handling of shocks, is the main cause of PIML failure, and ARZ residuals have a provably larger consistency error floor than LWR residuals.
