Researchers have developed a new framework called Adaptive Domain Decomposition Physics-Informed Neural Networks (ADD-PINN) to improve traffic state estimation from limited sensor data. This method addresses the tendency of traditional Physics-Informed Neural Networks (PINNs) to smooth out critical traffic flow dynamics. ADD-PINN uses a two-stage approach that first trains a general model and then refines it by creating specialized sub-networks in areas with significant traffic changes, outperforming existing methods in accuracy and training speed.
