In order to enhance the authenticity and accuracy simulation of pedestrians’ evacuation, a new multi-grid model is proposed. In the new model finer lattice is used, more chosen directions are offered and interaction forces including extrusion, repulsion and friction among pedestrians or pedestrians and construction are considered. A simple situation is studied in which pedestrians try to evacuate from a large room with single exit. In the process of simulation the multi-grid model realizes the dislocation distribution of pedestrians and overlap of partial track due to congestion by finer lattice. The influences of every parameter on evacuation time are also analyzed.
