Pedestrians are vulnerable in emergency evacuation situations, so evacuation planning is an important issue. Pedestrians are usually hurt due to disasters and congestion in the actual emergency evacuation. Therefore, an evacuation guidance that is adaptive to the real-time situation is necessary. This research proposes a method to create a dynamic emergency evacuation guidance system in buildings. The system considers the disaster factors and pedestrian factors to support the evacuation and to reduce the damage caused by disasters. The method consists of three steps for solving this problem. First, a shortest path tree is created according to evacuation signs. Second, based on the shortest path tree, a static floor field is created, which can be used in the Cellular Automata pedestrian simulation. And the last, a method for generating dynamic evacuation guidance considering disaster and congestion factors is developed. The proposed method has two benefits. First, adjusting the guidance by dynamic factors can help the pedestrians to avoid the disaster. Second, the computation time is short, which meets the requirement for emergency evacuation. In the case study, multiple exits and multi-area floor plan are used as an example to demonstrate the research method. The result of the research shows that the method is effective, and also has potential for the planning of dynamic emergency evacuation guidance.
