| With the rapid development of high-speed railway in our country, the condition that carrying capacity of high-speed railway passenger station is limited become more and more universal. The traditional method of calculating carrying capacity of station dose not considering the interaction between throat area and arrival-departure track. The main researching idea of this paper is to analysis the influence factors of carrying capacity of high-speed railway passenger station, on this basis, analyzing the relationship between throat area and arrival-departure track at station. This contribute to solving the problem of the shortage of carrying capacity of station.After an introduction of researching background and significance,this paper analysis the influence factors of carrying capacity of station:station design, transport organization mode, passenger organization mode. The design of throat area and that of arrival-departure track influnce each other. In the transport organization process, throat area connect with arrival-departure track closely.In the passenger transportation organization process,check-in process and passengers boarding process influence the train residence time on arrival-departure track,which affect carrying capacity of station largely. On the basis of analyzing the influence factors of carrying capacity of station, this paper analysis the influence factors of utilization rate of throat area and arrival-departure track. Then this paper analysis the relationship between utilization rate of throat area and utilization rate of arrival-departure track by using queuing theory:one equipment of throat area or arrival-departure track is in the state of leisure as another equipment is too busy.The relationship of size between the average waiting time each train of throat area queuing system Wq1 and that of arrival-departure track queuing system Wq2 depend on the number of trains, the occupied time of arrival-departure track by per train and the number of arrival-departure track. When many trains are received by arrival-departure track one day, the interaction between throat area and arrival-departure track become very obvious, for exampal, in the condition that there are 130 trains can be received by the receiving-departure yard one day, when the occupied time of arrival-departure track by per train is llmin and 17min, the utilization rate of throat area is 40.63% and 89.32% respectively, this is due to the crowded arrival-departure track exaggerate the leisure time of throat area, as a result,the utilization rate of throat area also changed. At last, Comprehensive analysis of the high-speed railway passenger station, considering various influence factors. Set up Petri net simulation model, verifying part of the conclusion of this paper. |
