Simulation Research On The Emergency Evacuation Of Large Railway Station

Modern large-scale railway station efficient combination High-speed Rail, railway, long-distance passenger transportation, urban rail, bus, taxi, crossing, pedestrian and so on. Shouldering the conversion within the city, outside the traffic function, its characteristic is building large scale, three-dimensional space layout and combined multifunctional aggregation, similar to these large-scale integrated construction, once completed construction is not easily change. If there is emergency in these large comprehensive buildings, the evacuation difficulty will increase. In this case, how will the large integrated within the building staff quickly evacuated to safe area is the priority among priorities of life in order to guarantee the safety of personnel.Based on this, this article from the transportation planning point of view, the introduction of the late effects of railway station function within the facility layout generated in the planning and design stage, to improve the efficiency of personnel emergency evacuation in the railway station emergencies. This paper based the evacuation trajectory. Using spectral clustering algorithm of railway passenger station functional areas. Taking Shenyang Railway Station elevated waiting room floor as an example, to test the validity of the method to improve the evacuation efficiency. First of all, this article from the large railway station building features, characteristics of evacuation characteristics to analysis the railway station system, as a basis for establishing the evacuation model, and from the evacuation, evacuation traffic organization, interior layout of the three aspects to analysis the influence on safe evacuation; Then, in the case of Shenyang Railway Station, establishment the three dimensional evacuation model Shenyang Railway Station overhead waiting layer, in this paper, with the subdivision of Shenyang Railway Station area overhead waiting layer unit, and based on the unit to establish a regional traffic network, region extraction unit personnel evacuation track traffic data, the establishment of its functional characteristics, spectral clustering algorithms for functional division of the region, according to the flow distribution characteristics of Shenyang Railway Station overhead waiting layer is divided into different functional areas. Finally, according to the different function area division of the re planning of Shenyang Railway Station overhead waiting layer, put forward different planning schemes, and were analyzed and simulated by using simulation software, calculates the evacuation time of evacuation, realize the three-dimensional display, and Shenyang Railway Station overhead waiting layer were compared, to verify the validity of the method to improve the evacuation efficiency.In accordance with the division of functional region of city idea, to re planning of railway station is the key research problem of this paper, the method to improve the evacuation efficiency purpose. In addition, function zoning can obtain many functional hot, such as personnel gathered or personnel demand aggregation, And finding frequent moving pattern of these regional there will be congestion problems will help alleviate the passenger peak, avoid a stampede.
