| Research Abstract |
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.
