| The rapid development of China's high-speed railway has promoted the convenience,speed and accessibility of people's travel,at the same time,it has played a role in promoting the comprehensive service quality of passenger transport across the whole society.High-speed rail station is not only the node of passenger distributing in high-speed railway network,but also under the guidance of the idea of "humanization" and"zero transfer",the high-speed rail station has become a public place for various modes of transport to connect seamlessly,which is playing an increasingly important role in urban traffic.In a word,the high-speed rail station has the characteristics of centralized flow,complex structure,fast flow,complex layout,multiple management(different transportation modes)and diversified services,etc.In the event of an emergency,how to evacuate passenger flow quickly and choose the appropriate evacuation plan under the condition of ensuring safety is an important and urgent problem.Based on the analysis of the emergency evacuation characteristics of HSR(high-speed rail)station,in this paper,we will construct a multi-exit evacuation model combined the Social Force Model and use Anylogic model to simulate the evacuation process of passengers,which can provide some supports for management decision making.The main research contents are as follows:1.The theoretical problems of emergency evacuation in HSR station are analyzed systematically.Based on the theory in transport histology,psychology and behaviorology of passengers,his paper analyzes the characteristics of passenger flow in HSR stations,the factors that affect the spontaneous escape and evacuation of passengers in emergencies,the general method of passenger flow emergency evacuation in passenger station,the common evacuation model of passenger and other basic problems.2.The calculation method of emergency evacuation capability of HSR station is studied.This paper analyzes various behavior choices of passengers in emergency and quantifies the delay behavior and panic behavior of passengers.Equipment capability of exit passageway is the key factor in determining the efficiency and safety of evacuation.This paper analyzes the different connections of station facilities from the station spatial structure and the flow of passengers,and puts forward the calculation method of the evacuation capacity under the single facility of HSR station and the different connection ways during evacuation.3.Constructing a evacuation model of passenger under multi-exit selection.Considering the influence of the field of view,people's conformity and panic psychology,the visual impact factors and the coefficient of conformity can be referenced to assess impact the psychological force among pedestrians and improve the social force model.Based on the objective function of export and the congestion effect,a multi-exit options model,which is combined with the improved social force model to construct a passenger evacuation model with multiple export options,can be proposed by using the export utility function.4.Example calculation.On the basis of systematically analysing the problems existing in the emergency evacuation of HSR stations at this stage,taking the Hangzhou East Rail Station Waiting Hall as a background,on the basis of collecting data of related equipment and passenger flow.All is to achieve:(1)Using Anylogic simulation software to build evacuation scenarios and evacuation processes;(2)Setting relevant parameters of emergency evacuation model of Hangzhou East Rail Station;(3)Simulating the emergency evacuation behavior of the passengers in Hangzhou East Railway Station Waiting Hall and the simulation of passenger group movement in the waiting hall under multi-exit options is realized to verify the validity of the model;(4)The simulation results are analyzed from the aspects of passenger flow,passengers' panic behavior,suitability of carrying luggage and the ability of evacuating equipment,and some related suggestions are put forward. |
