轨道交通机场线快慢车停站方案优化方法研究

为了提高轨道交通机场线的满载率，兼顾机场乘客和沿线乘客的出行需求，考虑到机场线市中心区段与郊区区段客流密度相差大的特点，提出市区与郊区分段开行快慢车的停站方案。建立以机场乘客节省时间最大化为目标函数的快慢车优化模型，对机场线郊区区段快车停站位置进行优化。并对连接浦东机场、虹桥机场和市中心的上海地铁2号线进行快慢车停站方案的优化。结果显示，开行快慢车不仅可节省机场乘客的旅行时间，保证列车满载率，还能节省一定的工程成本，具有较大的优化效益。

Optimization Methods Study of Express/Local Stop Mode on Airport Rail Line

In order to increase the share ratio of airport rail line, and give consideration to travel demand both of airport passengers and passengers along the railway, the express/local stop mode on airport rail line was adopted. The stop mode is adopted segmentally on urban and suburb because of the difference on passenger density. The paper established an express/local stop optimization model based on passenger travel time saved most. Taking Shanghai line 2 as a case, the model is proved efficient, which save much time for airport passengers, guarantee the load factor for trains, and reduce the engineering cost.
