| 摘 要： | 针对中国城市轨道交通线网规划中线网构架主要采用定性分析的情况,建立了轨道交通线网优化的目标函数和约束条件,并给出了模型的近似优化方法,将OD(起讫点)矩阵中距离过短的出行摒弃后,各交通小区形心按一定的规则连接成网,在这个网中寻求潜在直达客流运输效率最大的子网络作为虚拟轨道交通线网,然后结合规划道路网将虚拟轨道交通线网沿一定的城市道路铺设,形成实际的轨道交通线网规划方案。

| Abstract: | At present,urban rail transit network planning in Chinese cities mainly uses qualitative analysis.After establishing a rail transit network optimization objective function and constraints,the optimization model is developed.In this model,the trips whose trip distance is too short in OD matrix are abandoned.Then,the traffic zone centroids were connected into a network in which a subnetwork with maximizing the potential through passenger flow was regarded as a virtual urban rail transit network.Based on plann... |
