摘要
本文首先建立了高速公路交通控制系统设计和交通系统的计算机仿真所常用的宏观、动态、确定性交通流模型,并在此基础上,结合我国高速公路交通流的特点,提出了低密度区的可变速度控制策略,最后利用计算机仿真的方法模拟了受控交通流和未控交通流,其结果令人满意。
This paper presents a macro, dynamic, deterministic traffic flow model used in design offreeway traffic control system and compnter simulation of traffic system. On the bases of themodel and the characteristics of freeway traffic flow in China, it gives a variable speed con-trol strategy. Finally, the control and out-of-control traffic flow is simulated by using co-muter simulation method. The simulation resultse are very satisfactory.
