Research On The Method Of Passenger Flow Evacuation Simulation For The Emergencies In Large Passenger Station

Railway large passenger station is an important city infrastructure, it is a large public service place with a large passenger distribution activities. Along with the rapid development of high speed railway, the railway in the great cities of the large passenger station has become set any mode of transport in the integration of urban comprehensive transportation hub. Because of modern large passenger station have building structure is complex, customer service equipment is numerous, passenger flow distribution, involving a variety of travel mode transfer characteristics, so once the accidents, it may cause serious personal casualty and property loss and serious accidents. Therefore, how to aiming at the characteristics of the large passenger station, through the emergency evacuation rules under the passenger flow are analyzed, and on the basis of the science develop emergency passenger safety evacuation plan, improve its security emergency ability, to ensure the normal operation of large passenger station and the passenger’s life and property safety, have important practical significance.In view of the large passenger depot is a complex queuing service system, emergency evacuation of passengers, not only should consider emergencies in the passenger station activities of complex behavior, will also involves various streamline and numerous customer service equipment using the configuration and the influence of complex environmental factors. So, in view of the large passenger depot emergency passenger evacuation organization complexity, with the characteristics of advanced computer simulation technology of passenger evacuation law research, is the current situation in the field of a major issue.In this paper, to participate in the work of the Ministry of Railways key projects large passenger terminal operations management and intelligent service technology and deepening of scientific research, the topics of study on a Large-scale passenger station terminal emergencies passenger evacuation simulation method. Based on the analysis of present situation home and abroad, this paper made deep analysis and researches on characteristics of large-scale passenger station and emergency within it, the behavior rules of pedestrian traffic, the pedestrian movement simulation models and methods and the realization of large passenger safely evacuate simulation. Based on the theory research above, this paper made simulation on passenger flow emergency evacuation in Beijing south station, and then analyzed and evaluated the results. Using theory and method of system analysis, based on the emergency evacuation environment and pedestrian theory under emergency, this paper made deep analysis on the behavior rules of pedestrian traffic on the special condition of large-scale passenger station emergency evacuation, and the main factors affecting their behaviors when emergency occurs; This paper discussed the characteristics of simulation models used widely like cellular automata, magnetic field force and social force model, and simulation software like STEPS、SimWalk、Legion and AnyLogic, finally chose social force model and AnyLogic software to establish large-scale passenger station emergency evacuation model; Using simulation case got the service level of the classification standard; summed up simulation method and procedure of emergency evacuation streamline in large-scale passenger station, and combining with the actual Beijing south station elevated layer, using the Anylogic platform simulation technology, made dynamic simulation test and evaluation on emergency safe evacuation, got time, proportion of the successful evacuation and bottleneck of safe evacuation under different evacuation plans, and provide optimization suggestions for emergency safety management of Beijing south station。Provide decision basis for passenger flow safe evacuation of large-scale passenger station.
