In this study, we classified 16 kinds of arrows which are frequently found at the station as "straight arrows" and "polygonal arrows". Then we conducted a fundamental experiment using arrows as the sole experiment elements of the space. In this experiment, subjects made a direction judgment and wrote a progress route intuitively. In this way, we investigated the factors of causes that made people get lost at the station. The results we got from the experiment are summarized below. 1) As for all the 8 types of "straight arrows", subjects are apt to judge the direction as a plan indication rather than an elevation one. 2) The downward "straight arrows" may cause misunderstandings in the direction judgment. 3) In case of "straight arrows", except of rightward and leftward arrows, "It is difficult to do the judgment between the plan and the elevation indications." became the most important reason why the subjects got lost in the direction judgment. 4) Based on the experiment of "polygonal arrows", we found that some upward arrows worked particularly better indicating the direction and progressing the route. Also, subjects can easily understand these signs. 5) The downward "polygonal arrows" may cause misunderstandings in the direction judgment. 6) As for all of these 8 types of "polygonal arrows", "It is difficult to know the distance to the turning point." became the most important reason why the subjects get lost in the direction judgment. 7) In some cases of "polygonal arrows", the users may interpret them as elevation indications which the railway company does not expect. 8) It is possible that the U-turn arrows of "backward progress" indications are not working properly. In both of the "straight arrows" and the "polygonal arrows", the force of indications of the downward arrows is weaker than the upward ones. And the downward arrows are difficult to understand. It is necessary to investigate the causes in detail in the future. In addition, as for the "straight arrows", it was obvious that the users may confuse the direction of plan indications with the elevation ones. This became a factor which made people get lost at the station. According to "The Ecological Approach To Visual Perception", we think that the force of the indication will be increased by incorporating the linear perspective and the texture gradient in the signboard. However, this idea needs to be examined by more experiments in the future. Otherwise, when applying to the real situation of the space, there are more factors other than the arrow signs in the view range of the direction judgment, so we need to consider this influence multifaceted.

In this research, we conducted an interview survey using the evaluation grid method with elements of additional signs posted at the station as elements. As a result, we clarified the evaluation structure of preferable additional signs for users in the station and extracted considerations to be addressed for a better sign plan. The findings obtained are summarized below. · From the perspective of evaluating the additional sign of the station user, the four perspectives of "time reduction", "sense of security", "fatigue reduction" and "reliability" came up in this survey, and we found that these four factors are important. ·In order to raise the credibility of additional signs it is important to make it permanent rather than handwritten or handmade. ·In order to realize the movement smoothness contributing to above the three high-level concepts of "time reduction", "feeling of security", and "feeling of fatigue", “ease of finding" and "ease of judging the direction to the destination" is important. ·In order to achieve "ease of finding", "expression on the board surface itself and contents in the board" and "proper sign arrangement within the view" are important. ·The contents and directions drawn on the additional sign are easy to understand, making it easier to understand intuitively, and as a result it is easier to judge the direction of the destination. As a concrete design method of the "easy to understand contents and directions", " expression about contents in the board " and "proper sign arrangement on the plan of the station." are important. Compiling also the knowledge obtained in the past research, there were things that could be useful knowledge not only for additional sign but also for official sign , as described below. ·It is important to show the information that we want to emphasize in the sign beyond the height of the line of sight. ·The size of letters on the signboard surface and the posting height of the sign influence "attractiveness". ·"Enhancing movement smoothness" by the additional sign leads to an increase in the comfort of stations such as spiritual clearance and convenience as a result. We are considering "preference" from the results of an interview survey using elements of additional signs in this research. But from now on, based on the fact that differences in purpose affect the evaluation on the same sign, we want to explore better information provision methods for station users by considering the design and planning method each use purpose of the signs, such as assuming the situations at the time of using the station or conducting experiments using different elements.
