摘要:
给出了高峰客流方向严重不均衡定义。调查与分析了纽约地铁7号线皇后区广场站至法拉盛主街站区段三线改造，以及东京都JR常磐线北千住站至取手站区段四线改造的背景与运营情况。相比于四线改造方案，三线改造方案能节省成本，并避免非尖峰方向的运能浪费，但在列车周转上有难度。以上海轨道交通6号线为例，探讨了其三线改造扩能方案的可能性。针对第三线列车的周转难题，提出了单线铁路运营模式与重组非尖峰方向列车两种策略。
Abstracts:
The definition of seriously unbalanced directional passenger flow in peak hour is presented. Then the background and operation situation of the IRT Flushing Line′s triple-track reformation and the Jōban Line′s quadruple-track reformation are investigated and analyzed. Compared with quadruple-track reformation, triple-track reformation can save costs and use transport capacity effectively, while having difficulty in vehicle scheduling. Shanghai Metro Line 6 is taken as an example to discuss the possibility of expanding transport capacity by triple-track reformation. Targeting the vehicle scheduling difficulty for the train on third track, two strategies that single-track operation mode and reorganization of non-peak direction train are proposed.
