Development of Petri Net Simulator as Dynamic Pictorial Representation System and Its Application Studies to aide Transportation and Disaster Prevention Planning

1.基础研究成果(1)背景图像的网络构建及有色表示的加强：通过配置子菜单插入背景图像，可以在真实的规划空间图像上构建PETRI网模型，作为公众参与风格规划的基础；通过改变地点和颜色的形状和大小来扩展图形表示。(2)PETRI网数据库的构建：通过对真实的规划空间图像重建PETRI网，并在其SDATA文件中注释关键字，2.应用研究结果(1)公交优先方案仿真：通过对其背景图像进行网络构造，将实际公交发车道路上设置的公交先行区表示为交通Petri网，并通过可视化仿真，实现了公交优先方案的可视化仿真。(2)防灾规划仿真：构建了有序情况下防火系统的宏观Petri网，并通过增加危险网对其进行了扩展，并进行了对比仿真。(3)区域气候图像模拟：利用地点和颜色的形状、大小和颜色的差异，对建筑物火灾时的疏散进行了描述。(3)区域气候图像模拟：利用空间的形状、大小和颜色的多样性，对建筑物的疏散进行模拟。开发了一种用于模拟桥梁和周围山脉所产生的区域气候的四季图像的Petri网表示法。

1.Results of Fundamental Study(1)Net Construction on Its Background Image and Reinforcement of Colored Representation : By equipping submenu to insert background image, Petri Net model can be constructed on its real planning space image and can be used as basis for public involvement style planning.Also, pictorial representation are expanded by diversifying shape and size of places and colored.(2)Constraction of Petri Net Data Base : By rebuilding Petri nets on their real planning space images and commenting keywords in their Sdata files, develqed Petri nets are stored as data base for user of Petri Net Simulator.This data base is grown by both commenting from original developer and from user who refer to build their own net for their own planning.2.Results of Application Studies(1)Bus Priority Alternative Simulation : By using net construction on its background image, setting "bus advanece area"in real bus departure road is represented as traffic Petri net and by its visual simulation, departure buses are shown to advance to the forefront of setting road area at eveiy signal cycle.Traffic Petri net is also built to describe alternative operation systems for bus priority lane and better one is presented by their comparative simulation.(2)Simulation of Disaster Prevention Planning : Macro Petri net is constructed for fire prevention system during ordinal case and expanded for one during earthquake by adding hazard nets and comparative simulation are demonstrated.Also, evacuation in building at fire breakout is described by Petri net and influence of deviation from scenario is demonstrated by their simulation.(3)Simulation of Regional Climate Image : By using diversity of shape and size of places and colored, Petri net representation is developed to simulate four seasons image of regional climate created by a bridge and surrounding mountains.
