Dynamic Modes as Time Representation for Spatiotemporal Forecasting
Menglin Kong, Vincent Zhihao Zheng, Xudong Wang +1
This paper introduces a data-driven time embedding method for modeling long-range seasonal dependencies in spatiotemporal forecasting tasks. The proposed approach employs Dynamic M…
Anti-circulant dynamic mode decomposition with sparsity-promoting for highway traffic dynamics analysis
Xudong Wang, Lijun Sun
Highway traffic states data collected from a network of sensors can be considered a high-dimensional nonlinear dynamical system. In this paper, we develop a novel data-driven metho…
Bayesian calibration of traffic flow fundamental diagrams using Gaussian processes
Zhanhong Cheng, Xudong Wang, Xinyuan Chen +2
Modeling the relationship between vehicle speed and density on the road is a fundamental problem in traffic flow theory. Recent research found that using the least-squares (LS) met…
Securing Signal-free Intersections against Strategic Jamming Attacks: A Macroscopic Approach
Yumeng Bai, Saurabh Amin, Xudong Wang +1
We consider the security-by-design of a signal-free intersection for connected and autonomous vehicles in the face of strategic jamming attacks. We use a fluid model to characteriz…
Hankel-structured Tensor Robust PCA for Multivariate Traffic Time Series Anomaly Detection
Xudong Wang, Luis Miranda-Moreno, Lijun Sun
Spatiotemporal traffic data (e.g., link speed/flow) collected from sensor networks can be organized as multivariate time series with additional spatial attributes. A crucial task i…
Low-Rank Hankel Tensor Completion for Traffic Speed Estimation
Xudong Wang, Yuankai Wu, Dingyi Zhuang +1
This paper studies the traffic state estimation (TSE) problem using sparse observations from mobile sensors. Most existing TSE methods either rely on well-defined physical traffic…
