## Asymmetric optimal-velocity car-following model

Published in Physica A: Statistical Mechanics and its Applications, 2015

An asymmetric optimal velocity model is proposed for car-following theory, where the asymmetry between the acceleration and the deceleration is represented by the exponential function with an asymmetrical factor, which agrees with published experiments.

## Cluster statistics and quasisoliton dynamics in microscopic optimal-velocity models

Published in Physical Review E, 2016

In this paper, we show that there exists an emergent intrinsic scale that characterizes the interaction strength between multiple clusters appearing in the solutions of optimal-velocity models. The interaction characterizes the dynamics of the localized quasisoliton structures given by the time derivative of the headways, and the intrinsic scale is analogous to the “charge” of the quasisolitons, leading to non-trivial cluster statistics from the random perturbations to the initial steady states of uniform headways. The cluster statistics depend both on the quasisoliton charge and the density of the traffic.

## Optimal load control for frequency regulation under limited control coverage

Published in IREP Symposium, 2017

By framing the problem as an optimization problem and applying saddle-point dynamics, we obtain a control law that rebalances power and asymptotically stabilizes frequency after a disturbance. In this paper, we generalize previous work to partial control over all nodes in the network.
