. With the improved multi-grid model, we simulate the evacuation process and compare the simulation results with the … variable velocity, dislocable queuing, monopolizing exit and so on. Based on the experimental observation, we improve the multi-grid … model by considering the pre-movement time of each pedestrian, adopting variable velocity and using a new update procedure …

evacuation results, we studied the evacuation process using a multi-grid egress model. In the multi-grid model, a finer grid is … complex changes. The differences between the single-grid model and multi-grid model may be due to two main reasons. First, in … the multi-grid model, the pedestrians are out of alignment so that there are patches of unusable empty spaces as they are …

entitled “multi-grid model” is composed. In the new model, finer lattice is used; thus each pedestrian occupies multiple grids …
