摘要
应用复杂网络理论研究城市道路网的网络特性。选择三亚市的道路网作为案例,建立道路网络模型,定义参数,研究其拓扑特性;在此基础上,研究三亚市道路网的鲁棒性。研究结果表明,三亚市路网具有明显的复杂网络的特性,此网络对随机攻击具有一定的抵御能力,择优攻击对此网络具有很强的破坏力。
On the basis of study results of complex network theory and other related sciences,this paper analyzes the characteristics of urban road networks,which proceeds from modeling,calibration to obtaining relevant data concerning the topological characteristics of the road networks of Sanya.Based on the above results,it investigates the robustness of urban road networks of Sanya.It is found that Sanya urban road networks show obvious characteristics of complex networks,and it is strong against random attack,but weak against selective attack.
