On the Role of Non-Localities in Fundamental Diagram Estimation
Jing Liu, Fangfang Zheng, Boxi Yu +1
We consider the role of non-localities in speed-density data used to fit fundamental diagrams from vehicle trajectories. We demonstrate that the use of anticipated densities result…

Traffic state estimation using stochastic Lagrangian dynamics
Fangfang Zheng, Saif Eddin Jabari, Henry X. Liu +1
This paper proposes a new stochastic model of traffic dynamics in Lagrangian coordinates. The source of uncertainty is heterogeneity in driving behavior, captured using driver-spec…
