Safety Evacuation Of Weighted Crowd Under Emergencies In High-Speed Rail Station

With the development of high-speed railway in China, high-speed rail has been connected into a network, more and more people choose high-speed rail to travel. High-speed rail hub of high-speed internet line as a fulcrum, with high traffic, crowds and high density, in case of fire or other emergencies, it is easy to cause heavy casualties. At present, the emergency passenger on this kind of large public places of evacuation in many documents, most of them are the use of advanced computer simulation technology for their emergency evacuation, however, these documents do not consider the basic process of evacuation baggage problems.Based on this, in order to study the safety of emergency evacuation of people under a heavy burden at high-speed rail station. This paper first analyzed the characteristics and flow characteristics of the high speed rail station, and in-depth research on traffic behavior of pedestrian on the basis of it. Through comparative analysis of the various evacuation simulation software platform, and ultimately select Anylogic pedestrian evacuation simulation software to simulate emergencies under the emergency evacuation of passengers, due to the current evacuation simulation model most cases were not considered pedestrian carrying luggage, but in reality, the evacuation of the personnel evacuation speed and space utilization because of evacuees carried luggage sizes, ranging from weight and there were certain differences. Therefore, this article first through questionnaires, used contingency table analysis, qualitative analyzed of individual characteristics of pedestrians under emergency evacuation, and the correlation with the evacuation of luggage type and evacuation behavior choice. Then, evacuation experiments, paired samples t test based on the quantitative study of the effect of carrying small bags, rod boxes, backpacks, handbags (large), luggage on evacuation behavior, and by independent samples t-test method for the quantitative study of age, gender effects on pedestrian evacuation behavior.At the same time, used experimental data, considered a variety of mixed pedestrians’ personnel evacuation speed and luggage space occupancy rate, the model parameters of the existing pedestrian evacuation was modified, and used the station hall layer of the Chengdu East Railway Station as an example to carry out emergency evacuation simulation analysis. According to the simulation results, Obtain under various contingency plans for the corresponding passenger evacuation simulation average time to complete, and the experiment clearly demonstrated Chengdu East Railway Station and the mobility of the whole process of real-time distribution of the population, identify sensitive areas and evacuation bottlenecks. The results of the study can provide help and reference for the development of the Chengdu East Railway Station emergency evacuation.
