一种简单实用的行人模型及其在人群仿真中的应用
A Simple and Realistic Pedestrian Model for Crowd Simulation and Application
摘要：
如何模拟真实的行人人群是研究的一个主要挑战。已经提出了几种人群模拟模型，如细胞自动机模型，基于代理的模型，流体动力学模型等。重要的是要注意，基于代理的模型是能够，比其他方法，提供一个自然的描述系统，然后捕捉复杂的人类行为。在本文中，我们提出了一个多智能体仿真模型，其中行人的位置更新在离散的时间间隔。它考虑到一个简单的行人位于人群中的主要正常条件，如偏好，现实的环境感知等，我们的目标是模拟行人人群逼真的模拟可信的行人行为。模拟了典型的行人现象，包括行人在走廊中的单向和双向运动以及行人通过瓶颈的情况。进行的模拟表明，我们的模型是能够产生现实的行人行为。得到的基本图和瓶颈处的流量与经典结论和实证研究结果吻合得很好。希望本文的研究思路能对促进行人人群的建模与仿真起到抛砖引玉的作用。
英文摘要：
The simulation of pedestrian crowd that reflects reality is a major challenge for researches. Several crowd simulation models have been proposed such as cellular automata model, agent-based model, fluid dynamic model, etc. It is important to note that agent-based model is able, over others approaches, to provide a natural description of the system and then to capture complex human behaviors. In this paper, we propose a multi-agent simulation model in which pedestrian positions are updated at discrete time intervals. It takes into account the major normal conditions of a simple pedestrian situated in a crowd such as preferences, realistic perception of environment, etc. Our objective is to simulate the pedestrian crowd realistically towards a simulation of believable pedestrian behaviors. Typical pedestrian phenomena, including the unidirectional and bidirectional movement in a corridor as well as the flow through bottleneck, are simulated. The conducted simulations show that our model is able to produce realistic pedestrian behaviors. The obtained fundamental diagram and flow rate at bottleneck agree very well with classic conclusions and empirical study results. It is hoped that the idea of this study may be helpful in promoting the modeling and simulation of pedestrian crowd in a simple way.
