The purpose of research is to clarify the behavioral characteristics of the visually impaired in model courses. Experimental courses were a straight course without any obstructions, and 6 kinds of bent course. Subjects were 5 totally blind pedestrians, 5 eye-masked pedestrians and 5 normal sighted pedestrians. The results were that, in bent course, walking time of the totally blind was twice as much as that of the normal sighted, while that of the eye-masked, 5 times as much as that of the normal sighted. The totally blind walked at a speed of 62% of the normal sighted in bent course, while the eye-masked, at a speed of 25% of the normal sighted. The number of stops of the eye-masked was 2.4 times as many as that of the totally blind in the bent course. The time of stops of the eye-masked was 2.5 times as much as that of the totally blind in the bent course.
