摘　　要：研究基于元胞传输关系的高速公路节点耦合仿真模型的建立问题。从高速公路复杂网络系统综合仿真模型建立需要出发,基于各路段传输关系,定义不同类型节点并建立其流量动力学模型;按照节点传输关系建立高速公路节点耦合仿真模型。结合具体例子对所建立的节点动力学模型、节点耦合模型通过流量比较、宏观基本图比较予以验证,在此基础上进行拥堵下基于复杂网络牵制同步的高速公路多匝道协调控制实验研究。结果表明:所建立的交通流节点耦合仿真模型能够从不同尺度映射高速公路节点及其关系,可用于基于复杂网络理论方法的高速公路管理控制中。The establishment of freeway node coupling simulation model based on cell transmission was studied. The freeway system was studied from the perspective of complex network theory. From the comprehensive of freeway complex network system simulation model based on the transmission relationship of each section,different types of nodes of freeway were defined and their flow dynamics model was established. The node coupling simulation model of freeway was established based on the transmission relationship of nodes. Combined with the specific freeway network,the node dynamics model and the node coupling model were verified by comparing the flux and the macroscopic fundamental diagram( MFD). Based on the calibrated model and the pinning synchronization of complex network,the multi-ramp coordinated control of freeway under congestion was carried out.The results show that the freeway nodes and their relationships can be mapped from different scales by the traffic flow node coupling simulation model,which can be used in freeway management and control based on complex network theory.
