At present, different viewpoints and theories are put forward on divisions and transitions of traffic states in highway, for which decide the fundamental properties of traffic flow. Coherent-moving state, among these states, was firstly proposed in Helbing's paper [1] to discuss the hypothetical steady states in mixed traffic flow in highway traffic. Since then, possible explanations on existence, stability and transition of coherent-moving state have been proposed in other research. In the paper, fast simulation and scenario reproduction in cellular automaton model are taken to test and verify those assumptions. A two-lane highway scenario with variety of vehicle parameters is built to reproduce the situation where coherent-moving phenomenon is likely to occur. At last, according to the simulation results, we bring forward our explanations on coherent-moving state which may be helpful on further study.
