摘要
为提高城市公交系统的鲁棒性,制定了基于换乘的加边策略。以济南市公交-地铁复合网络为例,研究了网络的特性参数和鲁棒性,并提出基于换乘的加边策略提高网络鲁棒性。研究表明:复合网络具有小世界和无标度网络特性;网络在蓄意攻击下比随机攻击更具脆弱性;在介数攻击下,高度加边策略对网络鲁棒性提升较为显著,使网络瘫痪时被攻击站点比例提升50.46%;在随机攻击和度攻击下,高介数加边策略对网络鲁棒性提升较为显著,使被攻击站点比例分别提升23.35%和39.81%。
To improve the robustness of urban public transport system,an edge adding strategy based on transfer is formulated.Take the bus-subway composite network in Jinan as an example,the characteristic parameters and robustness of the network are studied,and an edge adding strategy based on transfer is proposed to improve the network robustness.The research shows that the composite network has the characteristics of small world and scale-free network;The network is more vulnerable than random attack under intentional attack;The network robustness is improved significantly by the high-degree edge addition strategy under betweenness attacks,which increases the proportion of attacked stations by 50.46%when the network is paralyzed;The network robustness is improved significantly by the high-betweenness edge addition strategy under random attacks and degree attacks,which increases the proportion of attacked stations by 23.35%and 39.81%respectively.
