abstract="Evacuation time taken by people to escape out of a room with obstacle is investigated by using a small-grid lattice gas model with different maximum velocities. The relationship between the evacuation time and the obstacle size and distance to the exit is investigated. The simulation results show that the evacuation time decreases when the obstacle is set appropriately under various densities. Additionally, the numbers of pedestrians escaping out of the room with and without obstacle at each time step are also compared and discussed in detail.<p />",
