| 摘 要： | 区域交通拥堵是通过排队链环逐级传播的,其结构类似于树结构分岔。如果不能实施及时有效的疏散控制策略,极有可能造成拥堵闭环。运用改进的中观交通仿真模型模拟基于事故的理想格子网络的交通拥堵形成和消散过程。依据交通拥堵传播的空间结构特征,利用禁止转弯(转弯禁限)与车辆途中更换路径的交通管制和诱导措施,首次提出了"树控制"策略缓解交通拥堵。仿真结果表明,合理应用提出的拥堵消散控制策略可以有效缓解交通拥堵的传播。 |

| Abstract: | Area-wide traffic jams mainly are caused by the propagation of vehicle queues from link to link,which is similar to the tree branches.If a timely and effective evacuation control strategy can not be implemented,a gridlock will be generated.The improved mesoscopic traffic simulation model was proposed to simulate the processes of traffic jam incident-induced formation and dissipation in a two-way rectangular grid network.According to the spatial structure of traffic jam propagation,vehicle movement bans and real time select path as traffic management measures were used to develop ’tree control’ strategies for the first time to disperse traffic jams.Simulation results show that the proposed strategies with appropriate application can be used to control the jam propagation effectively. |
