Modeling Stochastic Microscopic Traffic Behaviors: a Physics Regularized Gaussian Process Approach

no code implementations17 Jul 2020 Yun Yuan, Qinzheng Wang, Xianfeng Terry Yang

Leveraging a recently developed theory named physics regularized Gaussian process (PRGP), this study presents a stochastic microscopic traffic model that can capture the randomness and measure errors in the real world.

Macroscopic Traffic Flow Modeling with Physics Regularized Gaussian Process: A New Insight into Machine Learning Applications

no code implementations6 Feb 2020 Yun Yuan, Xianfeng Terry Yang, Zhao Zhang, Shandian Zhe

To address this issue, this study presents a new modeling framework, named physics regularized machine learning (PRML), to encode classical traffic flow models (referred as physical models) into the ML architecture and to regularize the ML training process.
