【摘要】：特大城市公共交通局部静态拥堵问题日益成为制约公共交通网络运行效率提高的关键。针对这一问题改变线路"同质性"假设,在线路"异质性"假设的基础上,提出了将轴辐式网络设计运用到公共交通领域中来,综合考虑居民采用公共交通方式出行的单位运输可变成本、不变成本、枢纽换乘成本等要素,将枢纽间大型客车干线运输所带来的规模经济效应进行量化,构建了基于单分配、多枢纽、混合式网络结构特征的轴辐式公共交通网络优化模型,旨在多重约束下通过枢纽布局降低网络运输成本,提高公共交通网络站点的可达性。最后根据模拟退火算法对模型进行求解,并通过算例分析与讨论的方式验证了模型的有效性。
[Abstract]:The problem of local static congestion of public transport in mega-cities has become the key to restrict the efficiency of public transport network.Aiming at this problem, the assumption of "homogeneity" of the line is changed, and on the basis of the assumption of "heterogeneity" of the line, it is put forward to apply the axis-radial network design to the field of public transportation.Considering the variable cost of unit transportation, invariable cost, transfer cost of hub and so on, this paper quantifies the scale economy effect brought by the transportation of large bus trunk line between hubs, and constructs a single distribution based on it.The optimization model of axle-spoke public transport network with multi-hub and hybrid network structure is designed to reduce the network transportation cost and improve the accessibility of public transport network sites through the layout of hubs under multiple constraints.Finally, the model is solved according to simulated annealing algorithm, and the validity of the model is verified by example analysis and discussion.
