(color online) Snapshots of the simulation test where the parameters value are set as follows: body radius r = 0.3 m, mass m = 80 kg, desired speed v i 0 = 1.5 m / s , characteristic time τ = 0.2 s, constants k = 20000 kg/s2, κ = 30000 kg/s2, A = 2000 N, and B = 0.08 m. This simulation represents that 200 evacuees distributed randomly in the 20 m×20 m room without smoke evacuate from the room through the 2-m exit.
