中文摘要：

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。

英文摘要：

In order to increase the share ratio of airport rail line,and give consideration to travel demand of airport passengers and passengers along the railway,the express and local train skip-stop mode on airport rail line was adopted. The skip-stop schemes were adopted separately in urban and suburban areas because of the passenger density differences. We established an express and local skip-stop schemes optimization model based on maximum passenger travel time saved. Taking Shanghai Metro Line 2 as a case study,the model is proved efficient because it can save much time for airport passengers,guarantee the full load ratio of trains,and reduce the engineering cost.
