Evacuation of crawlers and walkers from corridor through an exit

Evacuation processes of walkers (pedestrians) and crawlers are investigated by experiment and simulation. The experiments are performed for walkers and crawlers evacuating from the corridor (channel) with an exit. All students go on all fours in the evacuation experiment of crawlers. The video recordings and measurements of individual escape times are evaluated. The characteristics of evacuation processes are clarified experimentally. The evacuation process of students going on all fours is compared with that of walkers. Both experiments are mimicked by the lattice gas simulation, where each student is simulated by a biased random walker. The simulation results are compared with the experimental results. It is shown that both experiment results are consistent with the simulation results.
