Factors that were supposed to influence the model evaluating natural surveillance, 1) the transparency ratio of fences, 2) the types of fence frame, 3) the distance to the target, and 4) the angle toward fences, were verified by the trials through the full-size model. As the result, 3 consequences are found; 1) the larger the distance becomes and the smaller the transparency rate becomes, the worse the visibility becomes, 2) there are some points that the visibility does not become better even if the conditions get better, and 3) the visibility cannot be expected when the transparency ratio and the distance meet certain conditions.
