Finite element analysis on traffic flow problem (III)

Two influential traffic flow models formulated by Zhang, H. M. and Wu, Zheng are improved to include the lane-change problem, and the relations between the two models and the traditional speed-density hypothesis model are discussed. Runge–Kutta Discontinuous Galerkin Finite Element Method is generalized and applied to these three models for numerical solutions through which the traffic signal problem, lane-change problem and non-equilibrium traffic flow phenomena are well simulated.
