基于生灭过程理论，重新研究了高速公路交通集结的主方程方法，并对单车道高速公路交通模型中的聚类行为进行了研究。利用Greenshields模型重建了跃迁过程的跃迁概率，并由生灭方程导出了任意时刻t的团簇平均尺寸方程。数值实验表明，聚类行为随时间的变化很好。
We restudy the master-equation approach to aggregation in freeway traffic based on the theory of birth–death process, in which the clustering behaviour in one-lane freeway traffic model is investigated. The transition probabilities for the jump processes are reconstructed by using Greenshields' model, and the equation of the mean size of the cluster at any time t is derived from the birth–death equation. Numerical experiments show the clustering behaviours varying with time very well.
