Simulation Analysis Of Emergency Evacuation In Changsha South Station Based On The Maximum Agglomeration

With the advancement of the national economy,the people’s living standards have also been improving.The people’s demand for travel has not only arrived safely,but the people are more likely to get a fast,comfortable and convenient travel experience on the basis of pursuing safety.In the rail transportation mode,more and more passengers travel by high-speed railway.With the rapid development of high-speed railways in recent years,many regions and cities have benefited from this.It not only enhances the passenger transportation capacity,but also injects more vitality into the economic development.In recent years,many high-speed railway passenger stations have been built in the country.Among them,many railway passenger stations with large and medium-sized cities have large construction area,many facilities and facilities,and a large amount of passenger flow.If there is an emergency in the station(such as fire,terrorist attacks and other In case of emergency,etc.,the safety of the lives and property of passengers in the station may be threatened.This paper first summarizes the research status of the field of emergency evacuation and the research of the highest number of aggregates.It introduces the calculation method of the highest number of aggregates and compares the advantages and disadvantages.It analyzes the development and application of emergency evacuation research technology.In addition,this paper analyzes the types and characteristics of emergencies,and then introduces various time concepts of emergency evacuation.On this basis,the research of this paper is based on the social force model,using Anylogic software to simulate the emergency evacuation of passengers in the high-speed railway passenger station,setting passenger behavior parameters,perfecting the model,analyzing the classification scheme of pedestrian service level at home and abroad,and formulating A service level grading scheme that meets the research objectives of this paper.Choose the appropriate calculation method to calculate the highest number of people in the research group,and based on the perspective of the vision,appropriately expand the number of passengers set.On the basis of establishing the model and calculating the highest number of people gathered in Changsha South Station,according to the analysis and actual observation,it is known that the passengers starting from the station are basically waiting at the elevated level after entering the station.Therefore,the elevated waiting floor is selected as the research object.The model operation results show that the overall evacuation efficiency of the elevated waiting zone in Changsha South Station is higher under the current situation,but there are certain problems based on the perspective of the prospect.The research in this paper has certain reference value,which can provide reference and reference for the organization manager of Changsha South Railway Station.It can also be used as a reference for the adjustment of the station building.Figure 24,table 30,reference 59.
