城市应急漫游系统若干关键技术研究

STUDY ON SOME KEY TECHNIQUES IN CITY EMERGENCY ROAMING SYSTEM

提出一种建立城市应急漫游系统的虚拟现实技术解决方案。重点研究在3DMax中利用粒子系统和蚁群算法实现漫游场景中突发公共事件和人群疏散的模拟方法;提出一种基于节点分散度和伪随机比率路径选择规则,建立自适应蚁群算法模拟突发公共事件时人群疏散行为模型,给出在人群疏散行为模型中用到的节点分散度和伪随机比率的计算方法。

A solution using virtual reality technology for city emergency roaming system is studied and proposed in this paper. Study em- phasis is put on the simulation approach of public accidents and crowd evacuation in a roaming scene realised with particle system and ant col- ony algorithm in 3DMax. We present a path selection regulation, which is based on node dispersion degree and pseudo-random ratio, and build a crowd evacuation behaviour model in public emergency occurrence simulated by the adaptive-self ant colony optimisation, and provide the calculation method for the node dispersion degree and the pseudo-random ratio used in crowd evacuation behaviour model.
