既有大型客运站最高聚集人数仿真计算

Simulative Calculation on Maximum Number of Passengers Gathered in Waiting Room of Existing Large Railway Passenger Station

最高聚集人数是铁路客运站设计的重要指标,它决定了候车站房规模大小、投资多少以及各项相关配套用房的设置。提出旅客集散仿真的基本流程,根据具体列车发车时刻与发送人数建立基于Simio的仿真模型。最后,对沈阳铁路局大连站最高聚集人数进行了仿真计算,该站旅客最高聚集人数[3380,3600]之间,所得到单日旅客聚集高峰时刻为11∶55～12∶00与15∶55～16∶00。通过最坏情景法与聚集系数法同计算结果对比分析证明模型具有较高的可靠性和实用性。

The maximum number of passengers gathered in waiting room is an important index for the design of railway passenger station, which controls the station building＇s size, the investment scale and the outbuilding＇s layout. In the paper, a basic flowchart used for the simulation of passenger gathering and distributing was proposed, and a simulation mode was established based on the Simio according to the actual train-departure time and the passenger number. Finally, the maximum number of passengers gathered in waiting room of Dalian Station of Shenyang Railway Bureau was simulated and calculated. The calculation results show that the maximum number of passengers gathered in waiting room of this station is between 3380 and 3600, and the peak hours of passenger gathering are at 11 ： 55-12 ： 00 and at 15 ： 55-16 ： 00 in a single day. Through comparing the results of calculation with that of worst-case method and convergence factor method, it can be concluded that this simulation mode has higher reliability and practicability.
