Inter-vehicle communications

We're interested in fundamental interactions between traffic flow and communication layers in inter-vehicle communications or IntelliDrive systems. We have been working on such topics as multi-hop connectivity of instantaneous information propagation, broadcasting and adjustment of transmission ranges for different traffic conditions, and ns-2 simulations.

Network traffic flow theory

We're interested in formation, propagation, and dissipation of traffic congestion in a road network. Recently we've developed a new framework to analyze kinematic waves arising from various types of network junctions. Earlier we developed an efficient discrete kinematic wave model of network traffic flow, which can be considered as a type of Cell Transmission Model. We also studied on higher-order kinematic wave models, kinematic wave models of lane-changing traffic, First-In-First-Out violation, and so on.

Transportation network analysis

We're interested in fundamental interactions among route choice behaviors, traffic dynamics, and traveler information in transportation networks. We developed a new dynamical system model of static and dynamic traffic assignment problems. We also studied evacuation schemes in a road network.
