Visualisierung und Aufbereitung von Gebäudestrukturen für Personenstromsimulationen

Abstract

Within the scope of this bachelor thesis a program was developed for designing and subsequently editing two-dimensional scenarios for a simulation of critical crowd. With the aid of this so-called SinoGen generator and itsgraphical interface a user can create new topography files and save them in the required file format XML for a subsequent simulation. Special attention was paid to the possibility of importing and analyzing an existing CAD geometry in the DXF file format by the SinoGen tool. For this purpose a DXF parser was developed for picking simple two-dimensional geometric elements from a CAD drawing and for using them true to scale in a simulation of crowds.
Besides the reading of existing information on simulating an environment, the program should provide the opportunity to add new elements. Needed for a simulation are inter alia sources, to generate new pedestrian and targets, to remove persons from the topograhy again, after a fully simulated sidewalk. In addition, there was a need for obstacles and so-called pedestrian blocks representing a large number of crowded people at the beginning of a simulation.
