| 摘 要： | 基于元胞传输模型(Link-Node Cell Transmission Model)给出了路网交通流仿真流程.在Matlab环境下使用该流程对单向4车道高速公路上交通流进行仿真,并分析了其交通拥挤波的形成过程和消散过程.仿真结果表明:元胞传输模型能够很好地描述车辆排队形成和消散过程.因此,主干道宏观参数、交通事件的管理策略等对车辆的通行能力也有很大的影响.

| Abstract: | The paper devises the process of traffic flow simulation based on link-node cell transmission model.Then,flow and density of the single-direction of a highway with four lanes is simulated with Matlab,and the formation and dissipation of crowded waves of the highway is analyzed.The result shows that cell transmission model can well describe the formation and the dissipation of vehicles' queues.Therefore,highways' macro parameters and traffic incident management strategies have a great impact on the ability o... |
