摘要/Abstract

摘要： 公共建筑内的行人交通是一个群聚密度不确定、个体之间相互作用的非线性随机动态问题．计算机动态仿真是目前研究公共建筑物内行人交通流动力学特性的有效方法之一．文中针对主流仿真软件在模拟相同场景下行人疏散结果时存在差异的问题，分析仿真软件在模型性能上的差异，解释离散空间引致仿真误差的原因，同时引入保真度来评价仿真模型的精确程度．通过对比地铁站通道的实验数据和仿真结果，得出行人交通仿真性能与建筑物内环境密切相关的结论，验证保真度对仿真模型的重要性．案例结果表明，连续矢量空间多智能体仿真模型对再现公共建筑内行人交通的保真度高达87%．

Abstract:

The pedestrian traffic system in public buildings is a nonlinear stochastic dynamic system with uncertain cluster density and interactive individuals. At present,computer dynamic simulation is one of the effective methods to investigate the dynamic characteristics of pedestrian traffic flow in public buildings. In this paper,aiming at the difference in simulation results of pedestrian evacuation obtained by several major simulation softwares in the same scene,the performance differences of the simulation software models are discussed,the simulation error due to the discrete space is analyzed,and the accuracy of the simulation models is evaluated by means of fidelity analysis. By comparing the simulated results of the travel time in the channels of the metro station with the experimental ones,it is found that the simulation performance of pedestrian traffic is closely related to the building environment,and that fidelity is important to the simulation model. Moreover,case study indicates that the multi-agent simulation model based on continuous vector space is of a fidelity up to 87% for reproducing the pedestrian behaviors in complex public buildings.

Key words: public building, pedestrian traffic, simulation model, fidelity
