| There are many temples in Tibet.At the same time,with the rapid development of tourism,the density of people in scenic spots is increasing,this is followed by the danger of crowds of crowds and trampling,and evacuation of the crowd after the accident.Therefore,the law of movement and evacuation of crowds is studied using simulation software model,taking appropriate emergency measures and evacuation plans,it is important to reduce the possibility of accidents and casualties.For the commonly used crowd evacuation model theory,we generally study pedestrian movement path from macroscopic and microscopic aspects.The evacuation theory of the macro model is mainly applicable to places with small crowd density,while the microscopic model has a good simulation effect for the crowd with large density.According to the characteristics of the simulation case scenario,we select the social force model in the microscopic model as the evacuation theory in this paper.Taking Jokhang Temple as a simulation case,pedestrian evacuation simulation based on social force model is applied to pedestrian evacuation simulation software Anylogic,The simulation of computer simulation can not only simulate the evacuation of various scenes,through the adjustment of the corresponding parameters,repeated operations,more comprehensive control of the law of evacuation behavior,and put forward a reasonable evacuation plan.The main research work and conclusion of this paper are as follows:1.The commonly used evacuation models,such as fluid mechanics model,cellular automata model,lattice gas model and social force model,are summarized and compared.Social force model is selected by combining the environment characteristics of simulation cases,and the simulation research is carried out by the pedestrian simulation software Anylogic based on the social force model.2.The Jokhang Temple is selected as a simulation platform to build a simulation platform.The factors such as sex,age,speed and shoulder width of pedestrians are investigated.The simulation environment is perfected and the simulation results are more reliable and true.3.According to the crowded areas where people gather in different situations,the causes of congestion in this area are analyzed,and the corresponding evacuation plans are put forward,and the evacuation results are carried out by using the simulation software to observe the evacuation measures,and the evacuation measures are demonstrated. |
