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 firstly establishes the macro, dynamic and deterministic traffic flow models which are used in the design of traffic control system and the computer simulation of traffic system. On the basis of this, combined with the characteristics of expressway traffic flow in our country, Variable speed control strategy, and finally simulates the controlled traffic flow and the uncontrolled traffic flow by computer simulation, the result is satisfactory.
