This study quantitatively examines the behavior of pedestrians moving close to a person with a trolley bag or baby stroller. The data will prove useful in estimating how much extra space needs to be allowed for those with such gear, for example in a railroad station or other transport facility. The experiment was conducted on a crowded street in a Tokyo business district during the morning commute. A male assistant hired for the experiment was asked to walk in three directions with respect to pedestrian flow in four conditions for a total of 12 experimental situations. The study revealed how large evasive space is required in each situation.
