Abstract
This report has examined the effects of an intensive method of learning evacuation routes by a human behavior experiment under the assumption that there were four kinds of walking routes and the field of human vision was limited only to the downward direction to simplify the conditions in the field of vision. As a result, following findings have been obtained. (1) The more trials of evacuation are carried out, the less errors occur. But the crossings where errors occur are almost identical, and around the 5th crossing are observed the most errors. If there are 4 or less crossings where one must turn to the left or the right, at the 3rd trial almost all of the participants of about 90% or more can return correctly to the starting point. (2) At every trial there is found an tendency that the participants prefer to learn the direction at a crossing rather than the distance between crossings. Noticeably there are only a few people with whom almost no learning effects of the distance between crossings have been found even after 10 or more trials.
