In autumn of 2006, at the Vienna University of Technology the project TU Univercity 2015 was launched, which includes the modernization of the buildings and the concentration from the faculties of maximum two locations. In the context of this project, the Institute for Analysis and Scientific Computing intended to create a model to optimize the classroom assignment and simulate the processes in place at the university. This model, which is called MoreSpace, was realized mostly in the simulation language Enterprise Dynamics (ED), with exception of the part which calculates the times which the students need to change the lecture rooms. This outsourced part of the imulation is now the topic of this paper. The simulator is implemented in object-oriented programming language Java and connected via TCP / IP with Enterprise Dynamics. To model the dynamic behavior of single individuals an Agent-based system was chosen in which the individuals move on a discrete grid. The cell size is 0.125 x 0.125m, so that 1m2 consists of 64 cells. Each student takes 4 x 4 cells, or 0.5m x 0.5m. The move forward of people in a building is depending on several related factors. Some of these items are the density of the people in a group, the maximum speed which varies for each individual. These factors of course are in strong relation to the environment. In this case the difference in moving forward
in a roomily area or a staircase will be mentioned. It is also of crucial importance, whether a person is facing multiple other individuals. All this is relevant for the speed and thus for the required time which the students need to switch from location A to another location B, in our case.
