Microscopic study of orbital textures
Seungyun Han, Hyun-Woo Lee, Kyoung-Whan Kim
Many interesting spin and orbital transport phenomena originate from orbital textures, referring to -dependent orbital states. Most of previous works are based on symmetry…
Steady state solutions of hydrodynamic traffic models
H. K. Lee, H. -W. Lee, D. Kim
We investigate steady state solutions of hydrodynamic traffic models in the absence of any intrinsic inhomogeneity on roads such as on-ramps. It is shown that typical hydrodynamic…
Macroscopic traffic models from microscopic car-following models
H. K. Lee, H. -W. Lee, D. Kim
We present a method to derive macroscopic fluid-dynamic models from microscopic car-following models via a coarse-graining procedure. The method is first demonstrated for the optim…
Phase diagram of congested traffic flow: an empirical study
H. Y. Lee, H. -W. Lee, D. Kim
We analyze traffic data from a highway section containing one effective on-ramp. Based on two criteria, local velocity variation patterns and expansion (or nonexpansion) of congest…
Dynamic States of a Continuum Traffic Equation with On-Ramp
H. Y. Lee, H. -W. Lee, D. Kim
We study the phase diagram of the continuum traffic flow model of a highway with an on-ramp. Using an open boundary condition, traffic states and metastabilities are investigated n…
Origin of synchronized traffic flow on highways and its dynamic phase transitions
H. Y. Lee, H. -W. Lee, D. Kim
We study the traffic flow on a highway with ramps through numerical simulations of a hydrodynamic traffic flow model. It is found that the presence of the external vehicle flux thr…
