摘　　要：目的深入研究多模式交通网络的复杂特性,推动不同交通模式之间的协同发展,以有效缓解城市交通拥堵。方法利用复杂网络的分析方法,以乌鲁木齐市交通为研究对象,构建多模式交通网络模型。对多模式交通网络的静态特性进行对比分析;运用仿真实验,检验多模式交通网络的鲁棒性;针对上述分析结果,提出相关优化建议。结果多模式交通网络平均最短路径长度较大而聚类系数较小,地铁-公交网络和快速公交-公交网络均表现出幂律分布特征,而地铁-快速公交网络呈现出高斯分布特性;多模式交通网络在面对攻击时展现出了优越的鲁棒性。结论乌鲁木齐市多模式交通网络是典型的小世界网络,相较于其他城市,交通规划和设计尚处于相对滞后的阶段,需持续完善和提升;多模式网络的鲁棒性优于对应单模式网络,内部结构的紧密度更高。Purposes—To study thoroughly the complex characteristics of multimodal transportation networks,and promote synergistic development among various transportation modes,with the purpose of effective alleviation of urban traffic congestion.Methods—Analytical techniques in the field of complex networks,with the transportation system in Urumqi as the research object,is used to develop a model of the multimodal transportation network.The static properties of the network undergo comparative analysis,and simulation experiments are utilized to evaluate the robustness of the network.Based on the findings from the said analyses,pertinent recommendations for optimization are proposed.Results—The average shortest path length of Urumqi's multimodal transportation network is relatively large,while the clustering coefficient is small.Both the metro-bus network and the BRT(bus rapid transit)-bus network exhibit the characteristics of power-law distribution,while the metro-BRT network shows the characteristics of Gaussian distribution.Furthermore,Urumqi's multimodal transportation network produces superior robustness against attacks.Conclusions—The multimodal transportation network in Urumqi demonstrates the characteristics of a small-world network.In comparison to other cities,the transportation planning and design in Urumqi are still relatively underdeveloped and require continuous improvement and upgrading.Furthermore,due to its more compact internal structure,the overall robustness of the network surpasses that of corresponding single-mode networks.
