基于复杂网络理论建立高速公路网络演化模型,并对该模型的度和度分布关系进行分析。分析结果表明,该类型网络最终会演化成无标度网络,具有小世界性特征。为了研究该网络在遭受不同性质攻击时网络具有的连通效能性,对江西省高速公路网络分别进行随机性和选择性攻击,结果表明,网络的连通效能性与移除节点的数量有很大的关系,在遭受不同性质攻击时均具有一定的连通效能性,但在遭受选择性攻击时,网络迅速分裂成众多子网络,连通效能性急剧下降为0,网络在短时间内就处于崩溃状态,为高速公路的规划、建设提供依据。
Based on the complex network theory, the evolution model of expressway network is established, and the relationship between degree and degree distribution of the model is analyzed. The analysis results show that this type of network will eventually evolve into a scale-free network with small-world characteristics. In order to study the connectivity efficiency of the network under different kinds of attack, the random and selective attacks on the expressway network in Jiangxi Province are carried out respectively. The results show that the network connectivity and the number of removed nodes are very large However, in the case of selective attack, the network quickly split into many sub-networks, and the connectivity efficiency drops sharply to zero. The network is in a state of collapse in a short time, Provide the basis for the planning and construction of the expressway.
