Adaptive Traffic Speed Estimation
Procedia Computer Science, 2014 AbstractActive traffic management aims to dynamically manage congestion based on existing and predicted traffic conditions. A challenge in this is that it is not usually possible to process data in real-time and use the output in control algorithms or in traveler information systems.

Traffic Regulation via Controlled Speed Limit [PDF]
SIAM Journal on Control and Optimization, 2017 We study an optimal control problem for traffic regulation via variable speed limit. The traffic flow dynamics is described with the Lighthill-Whitham-Richards (LWR) model with Newell-Daganzo flux function. We aim at minimizing the $L^2$ quadratic error to a desired outflow, given an inflow on a single road.

Mechanism of Traffic Jams at Speed Bottlenecks
Procedia Computer Science, 2014 AbstractIn the past 20 years of complexity science, traffic has been studied as a complex system with a large amount of interacting agents. Since traffic has become an important aspect of our lives, understanding traffic system and how it interacts with various factors is essential. In this paper, the interactions between traffic flow and road topology
