摘要
We use the car-following model （Phys. Rev. E 72 （2005） 066124） to further analyse the two-lane traffic waves. Our numerical results show that in the two-lane traffic, there exist triangular shock, soliton wave and kink wave which appear in the stable, mestastable and unstable regions of headway-sensitivity space, respectively. Compared with the single-lane traffic, it is found that the lateral distance has little effect on the formation of triangular shock and soliton wave although the lateral distance can enlarge the stable region and can reduce the mestastable and unstable regions.
