摘要:
基于计算机试铺运行图的仿真模拟方法，以广州市域快速轨道交通18号线和22号线为例，以快慢车呈组合周期化开行、快车优先且尽量保证慢车的旅行速度最大、慢车被越行的次数尽量少为原则，研究了限定越行站条件下不同越行地点、不同快慢车开行比例及不同共线交路开行比例对线路通过能力的影响规律，得到了16个不同运营方案下的线路最大通过能力。仿真结果可为线路的开行方案优化及增能措施提供支撑。
Abstracts:
Based on the simulation method of computer test operation diagram, taking Guangzhou urban rapid rail transit Line 18 and Line 22 as examples, according to the principle that the express/local trains are operated in a combined periodic manner; the express train is given priority, the travel speed and the overtaken times of local train is guaranteed to be the maximum and the minimum respectively. Under the condition of limited overtaking station, the influence of different overtaking places, different ratio of express/local trains and different proportion of collinear operation trains on the line passing capacity is studied. The maximum line passing capacity of 16 different operation schemes is obtained. The simulation results can provide support for the optimization of line operation scheme and capacity enhancement measures.
