Discussion

Online approach enhances density estimate robustness amid noisy data, improving traffic management techniques.

Real-time traffic density estimates improve accuracy despite noise, enhancing overall traffic data reliability.
Key findings note that employing adaptive weights leads to more precise density estimates under variability.
Methodological approach utilizes physics-informed neural networks for continuous model identification and update.
May support more effective traffic management strategies by producing reliable density estimates during fluctuations.

Wilkman et al. (2025) studied this question.
