Walking simulation experiments were conducted, and the resulting data of route memorizing mechanism was quantitatively analyzed. Based on the post-experiment interviews, the memorizing units are identified as turning corners in the walking routes. Using a quantitative method newly developed by authors, the memory loads are derived. It is shown among others that a subject on average can proceed two turnings per one map consultation, and that the least memory capacity person memorizes half of the average person, whereas the most can three times of the average person.
