A two-lane lattice hydrodynamic model with heterogeneous lane changing rates

Capturing lane changing behavior is crucial when developing a traffic flow modeling and optimization algorithm. This paper presents a two-lane lattice hydrodynamic model with consideration of heterogeneous lane changing rates over space. We further derive its linear stability condition for this extended lattice model with heterogeneous lane changing rates. Numerical experiments are carried out to investigate the effect of different values and percentages of lane changing rates on the system stability. This study contributes to the modeling and analytical techniques involving use of inter-vehicle communications.
