【摘要】：传统拓扑网络级联失效可靠性模型,大多忽略路网设施与运输需求的空间分布问题。在复杂分层网络结构模型基础上,提出了城际路网的级联失效可靠性仿真模型,对中国内地城际路网的可靠性进行了实例仿真研究。仿真数据表明:稳定配流状态下,长三角、环渤海、京津唐、珠三角地区OD负载聚集程度最高。当OD总量大于一个临界值时,针对高OD负载区域路段的蓄意攻击,容易引起城际路网系统的级联崩溃,其中长三角地区对蓄意攻击最为敏感。实验结果显示,该模型能够有效仿真分层网络的空间结构特征对路网级联失效可靠性的影响作用。
[Abstract]:The traditional topology network cascade failure reliability model mostly ignores the spatial distribution of road network facilities and transportation demand. Based on the complex hierarchical network structure model, the cascade failure reliability simulation model of intercity network is proposed, and the reliability of intercity network in mainland China is studied by an example. The simulation data show that the OD load concentration is the highest in the Yangtze River Delta, the Bohai Sea, the Beijing-Tianjin-Tangshan and the Pearl River Delta. When the total OD value is greater than a critical value, the intentional attack on the section of high OD load area is liable to cause the cascade collapse of the inter-city network system, especially the Yangtze River Delta region is the most sensitive to deliberate attack. Experimental results show that the model can effectively simulate the effect of spatial structure characteristics of hierarchical network on the reliability of cascade failure of road network.
