To inspect the suitability of using the ordinary wearing elderly simulator, which is called "INSTANT-SENIOR", instead of senior, the walking time and the behavior of the group with the ordinary and "INSTANT-SENIOR" are compared with those of the ordinary and senior. As the result, we concluded that "INSTANT-SENIOR" is available as the subject to model the walking behavior of the group evacuation from the point that they become obstacles to the ordinary as the senior do and they won't change the speed during the repeated experiments. Therefore, the experiment of the group evacuation using "INSTANT-SENIOR" as subject is shown in this paper.
