【摘要】：考虑到城市路网中不同路段所处的位置不同,其重要程度亦不同,将体现路段在路网中位置的k-shell值引入城市路网关键路段的识别中,提出了基于度+k-shell值的识别方法;该方法应用复杂网络理论对城市路网进行网络拓扑映射并分析网络特性,利用所提出的方法对网络中节点进行重要性排序,并分析依该排序的路段次序失效后对城市路网连通可靠性的影响;以西安市三环内路网为例,将文中所提出的方法与已有基于度值和介数值的测度方法进行了对比,表明基于度+k-shell值的方法较已有的两种方法能提高网络的连通可靠性。研究结果可为城市道路交通管理部门进行城市道路施工方案的优化、交通应急预案的制定等提供决策及理论支持。
[Abstract]:Considering that different sections of urban road network are located in different positions and their importance degree is also different, the k-shell value which reflects the location of road sections in the road network is introduced into the identification of key sections of urban road network, and a recognition method based on degree k-shell value is proposed.In this method, the complex network theory is used to map the urban network topology and analyze the characteristics of the network, and the proposed method is used to sort the importance of the nodes in the network.This paper also analyzes the influence of the sequence failure of these sections on the connectivity reliability of the urban road network, taking the San Ring Road Network in Xi'an as an example, the proposed method is compared with the existing measurement method based on the degree value and the intermediate value.The results show that the method based on degree k-shell value can improve the connectivity reliability of the network.The results can provide the decision and theoretical support for the urban road traffic management department to optimize the urban road construction plan and to formulate the traffic emergency plan.
