摘要
为研究多式轨道交通子网络系统之间的耦合关系,基于复杂网络理论计算其拓扑指标值及耦合协调度,构建了多式复合网络拓扑模型。分析了复合网络的拓扑指标值变化,提出了结合网络规模、拓扑结构、鲁棒性、运输能力、换乘比例和功能造价等因素的多式轨道交通网络耦合协调度计算方法,并运用重庆2019年10月的轨道交通网络进行了实例分析。结果表明:复合后的网络具有更大的平均度、更小的最短路径长度,这一时期复合网络的耦合度为0.988,协调度为0.678,耦合程度较高,协调程度一般;4个子系统各指标下的耦合度和协调度数值上差异较大,但都随着系统数量的增多,整体的耦合性和协调性大多呈下降趋势。
To study the coupling relationship between multi-standard rail transit sub-network systems, the topological index value and the coupling coordination degree are calculated based on the complex network theory, and then the multi-standard composite network is constructed. The change of the topological index value of the composite network is studied. The calculation method for the coupling coordination degree of the multi-standard rail transit network is proposed combining factors such as network scale, topology,robustness, transportation capacity, transfer ratio and functional cost. The Chongqing rail transit network(in October 2019) is finally used to do case analysis. The results show that the composite network has a greater average degree and a smaller shortest path length. The coupling degree of the composite network is 0.988, the coordination degree is 0.678, the degree of coupling is high, and the degree of coordination is average. The values of the coupling degree and coordination degree of each index of the four subsystems are quite different, but as the number of systems increases, the overall coupling and coordination degree tends to decrease.
