Building Information Model Based Fire Evacuation Simulation (YBIMS)
The aim of the "Building Information Model Based Fire Evacuation Simulation (YBIMS)" project numbered 121Y099 is to create a geographical information-based simulation platform where fire evacuation scenarios can be dynamically analyzed by ensuring interdisciplinary interaction.

IN PROJECT SCOPE
ABOUT PROJECT MANAGEMENT
By integrating data from different sources into the international standard three-dimensional Building Information Model (BIM), fire simulation, three-dimensional risk maps and agent-based modeling will be brought together in an innovative way on the same platform.
The aim of the project is to provide decision makers with the opportunity to make effective decisions for very high-risk and conceptually complex fire evacuation scenarios by virtualizing human behavior, environment and process steps during fire evacuation. The project will be carried out between 2022 and 2024.
EVACUATION SCENARIO
CREATION OF THE BUILDING INFORMATION MODEL
Within the scope of the project, ITU, Faculty of Civil Engineering and Annex Building were modeled at LoD 300 - 350 detail level in accordance with examining the required fire resistance periods and observing the scenarios involving the actors.
TEST RESULTS OF OBJECT EXTRACTION ALGORITHMS
Photogrammetric techniques were also used during the creation of BIM. Scanning studies were carried out in the selected test area with Leica C10 laser scanner equipment.
STATISTICAL ANALYSIS OF INDOOR OBJECT EXTRACTION SUCCESSES WITH DEEP LEARNING
Three-dimensional object detection algorithms using YOLO architecture were used to extract information from the project point cloud.
DYNAMIC FLAME AND SMOKE SIMULATION
The YBM model was transferred to the PyroSim environment, and a fire simulation was carried out by selecting a fire source of 1000 Kw/m2 in the new environmental building, which is the test area.
STATIC RISK MAPS INCLUDING STRUCTURAL RISKS
Within the scope of the project, it was aimed to create static risk maps by creating a "Building Risk Index" that includes all risk parameters and by making a holistic static risk assessment within the building.
MAPS OF INDOOR NAVIGATION NETWORKS
Indoor navigation networks have been created on YBM using various tools and methods.
The project number 121Y099 named Building Information Model Based Fire Evacuation Simulation (YBIMS) is supported by TUBITAK-1001 ARDEB.
