A Concurrent Switching Model for Traffic Congestion Control

no code implementations11 Apr 2022 Hossein Rastgoftar, Xun Liu, Jean-Baptiste Jeannin

We introduce a new conservation-based approach for traffic coordination modeling and control in a network of interconnected roads (NOIR) with switching movement phase rotations at every NOIR junction.

A trained humanoid robot can perform human-like crossmodal social attention and conflict resolution

no code implementations2 Nov 2021 Di Fu, Fares Abawi, Hugo Carneiro, Matthias Kerzel, Ziwei Chen, Erik Strahl, Xun Liu, Stefan Wermter

While the human performance was overall superior, our trained model demonstrates that it can replicate similar attention responses as humans regarding the congruency and incongruency performance.

Boundary Control of Traffic Congestion Modeled as a Non-stationary Stochastic Process

no code implementations26 Mar 2021 Xun Liu, Hossein Rastgoftar

The success of the proposed traffic boundary control is demonstrated by simulation of traffic congestion control in Center City Philadelphia.


Conservation-Based Modeling and Boundary Control of Congestion with an Application to Traffic Management in Center City Philadelphia

no code implementations31 Jan 2021 Xun Liu, Hossein Rastgoftar

By classifying the streets as inlets, outlets, and interior nodes, the model predictive control (MPC) method is applied to alleviate the network traffic congestion by optimizing the traffic inflow and outflow across the boundary of the NOIR with consideration of the inner traffic dynamics as a stochastic process.


Hybrid Low-order and Higher-order Graph Convolutional Networks

no code implementations2 Aug 2019 FangYuan Lei, Xun Liu, Qingyun Dai, Bingo Wing-Kuen Ling, Huimin Zhao, Yan Liu

With higher-order neighborhood information of graph network, the accuracy of graph representation learning classification can be significantly improved.
