Tensor-based modeling and computation emerge prominently with urgent demands from practical applications in the big data era. With the intrinsic sparsity in real data sets and the dimensionality reduc...
Influence of Traffic Flow Patterns on Air Quality inside the Longest Tunnel in Asia
Hsueh-shan Tunnel Air pollutants Traffic flow Piston effect
2016/3/28
The long tunnel is a fixed, semi-closed environment where excessive concentrations of air pollutants are easily
accumulated. This can potentially have a serious affect on drivers' health, especially ...
Analysis of kinematic waves arising in diverging traffic flow models
Kinematic wave models diverging traffic Riemann problem supply-demand space
2010/12/13
Diverging junctions are important network bottlenecks, and a better understanding of diverging
traffic dynamics has both theoretical and practical implications. In this paper, we first
introduce a c...
Fokker-Planck Asymptotics for Traffic Flow Models
Traffic Flow Modeling Fokker–Planck Equations
2010/12/6
Starting from microscopic interaction rules we derive kinetic models of Fokker–Planck type for vehicular traffic flow. The derivation is based on taking a suitable asymptotic limit of the correspondin...
Calibration of the Particle Density in Cellular-Automaton Models for Traffic Flow
Particle Density Traffic Flow Cellular-Automaton Models
2010/4/2
We introduce density dependence of the cell size in cellular-automaton models for traffic flow, which allows a more precise correspondence between real-world phenomena and what observed in simulation....
