Expressway traffic flow model study based on different traffic rules

Junwei Zeng, Xiao Feng, Senbin Yu, Yongsheng Qian,
In this paper, two cellular automata traffic models are proposed to simulate the operation of expressway. The results show that the flow rate and the average velocity are generally equal in the same density which is different among the lanes. The analysis of lane changing times and the velocity total deviation show some characteristics which are difficult to be explained by the phase transitions under the fundamental diagram theory. Therefore, the concept of lane changing probability is introduced, and it is concluded that the speed-limit rule can reduce the motivation of lane changing effectively.
