基于智能体的热点街区游人游憩模拟研究

Research on Recreation Simulation of Tourists in Hot Block Based on Intelligent Agent

近年来,各大热点街区的游人数量日益增多,因为区域人流密度过大导致风险事故发生的概率也随之增大.针对街区内的游人游憩过程模拟和风险评估需求,以北京南锣鼓巷街区为例,实地调研分析街区空间特征和游人属性特征,研究游憩行为规律,基于多智能体模拟方法设计街区游憩模型,并应用MASON开源库、GIS技术和JAVA WEB技术开发南锣鼓巷街区的游人游憩模拟平台,实现了基于各入口激光客流数据模拟整个街区完整游憩过程的实验,同时实时可视化表达模拟过程和结果数据,让管理者可通过平台查看街区内游人区域分布,掌握游人游憩规律.成果对分析街区限流方法的科学性、提高街区安全管理水平具有重要意义.

In recent years,the number of tourists in major hotspot blocks is increasing,and the high density of regional human flow leads to an increase in the probability of risk accidents.Aiming at the needs of simulation and risk assessment of recreational process of tourists in the block,taking Nanluogu Lane block in Beijing as an example,the spatial characteristics and attributes of tourists in the block are investigated and analyse,and the rules of recreational behavior are studied.Based on multi-agent simulation method,and using MASON open source library,GIS technology and JAVA WEB technology the simulation platform for tourists recreation in Nanluogu Lane block is developed.The experiment of simulating the whole recreation process of the block is realized based on the laser passenger flow data of each entrance,and the simulation process and result data in real time are visualized,so that managers can view the distribution of tourists area in the block and master the rules of tourists recreation through the platform.The results are of great significance for analyzing the scientificity of the method of block current limiting and improving the level of safety management in the block.
