Study On The Bottlenecks Identification Methods Of Distributed Network In Comprehensive Passenger Hub

Bottlenecks identification methods internal the Large-Scale Comprehensive Passenger Hub is one of most important things about the Hub planning and designs, and so is an important problem that needs to be solved about the Hub construction and operation management practical. This paper mainly studies the Bottlenecks of distributed network identification Methods inter the Hub based on facilities layout and passenger streamlines analysis. The main context as following;Firstly, adopted means investigated the speed of passengers'walking at the channel facilities, then set the parameters reasonable according to practical situation to analyze the distributed capacity of the channel facilities by simulation, the analysis models on distributed capacity of the channel facilities were built by simulation data fitting.Secondly, adopted simulation means to explain the bottlenecks formation mechanism by the basic facilities layout and passenger streamlines analysis, quantitative analyses the bottlenecks identification which caused by streamlines interleaving and streamlines conflict.Thirdly, taken optimized layout of facilities as the bottlenecks identification basis; set discrimination standard on bottlenecks identification combining simulation data base on the bottlenecks formation mechanism classification, classed the bottlenecks grade by restriction of bottlenecks. Then, the paper proposed the relative mitigation measures.Finally, this paper takes Beijing South Railway Station as the study background, combining with the method of dynamic simulation and dynamic evaluation the distributed process underground first story in coming future, identifies the bottlenecks during the distributed process underground first story, puts forward the improvement measures relieving bottlenecks.
