Extending a Pedestrian Simulation Model to Real-world Applications

Although recent advances in sensor technologies draw our attention to indoor spaces, no fully functional indoor 3D models are available as of now. Researchers in 3D modeling field have focused on representing 3D volumes using B-rep method and suggested different theoretical types of topological relationships. However, very few of them are related with explicit implementations for indoor spaces. Pedestrian evacuation simulation has been an active topic that targets scientific investigation of crowd behaviors in indoor areas. However, most simulations found in the related literature have been carried out using experimental settings without being linked to real-world applications. The purpose of our study is to propose a method to extend a pedestrian model to real world applications. First, we suggest a simplified 3D model that can be efficiently applied to indoor simulation and show how to build the model using a spatial DBMS. Then, we show a process to perform a pedestrian simulation using the proposed 3D model of a real campus building.
