In view of the rapid large scale development of underground in the central big cities, especially around terminal stations, evacuation experiments have been conducted with 79 subjects using an underground shopping mall near Tokyo Station actually in service after business hours. Four groups of 20 subjects started from different locations and time to “escape” from any of emergency exits was measured for each subject. 12 out of the 79 subjects wore elderly simulator to compare evacuation behavior of elderly and that of younger people. The evacuation behavior was also monitored by video cameras and escape route of each subject was reproduced afterwards. Five experiments were conducted using the lighting conditions and layout of emergency exits as parameters. The starting point was changed from experiment to experiment, not making any subject repeat similar selection of escape route. The shopping mall is composed of grid of passages, and is installed with escape route sign lights on every passage according to Fire Service Law. In every experiment, it was observed that considerable portion of subjects did not select right passage toward nearest exit at intersection nor passed over right exits. These are not compliant with widely accepted assumption for deterministic modeling of evacuation in mall-like facility. Factors dictating the probability to select right passage at intersections and that to recognize emergency exit are analyzed from the experimental data.

This study investigates pedestrian avoidance behaviors in a crowd. In order to appreciate avoidance behaviors in detail, the new graphic illustration method, called “Pedestrian-Perspective Movement Tracking Diagram” was developed in this paper. This illustration method packs a sequence of pedestrian movement from the pedestrian's perspective visually in one picture. The results of our experiment show for example detouring avoidance behavior can be observed after pedestrians reduce their speed. A case study in a real railway station was also carried out applying our new method to observe avoidance behaviors in a more complex pedestrian flow.

This study examines the relationship between activities of users in cafes and spatial factors of the cafes from the viewpoint of user's seat occupation. ’The Third Place’ originally proposed by Ray Oldenburg means the social surroundings apart from two usual social environments, home and workplace. The some of cafes in Japan, however, promotes the use of the cafe for private working spots as the third place. Observational investigation was conducted in cafes of a same group company, six shops and ten floors. Seat occupation and activities of each cafe user were recorded once per hour from 10 a.m. to 6 p.m. on August 2011. A Total of 5401 (person-hour) data was collected in ten days on weekdays. This study reveals activities of cafe users from the aspects of the shop location in Part 1 and from the aspect of the spatial factors in Part 2. Therefore, it is possible to provide the space to fit the user's needs by considering the location aspects and the spatial aspects. In this paper (part. 2), activities in the cafe were classified into three types: A) Output-based working, B) Input-based working, and C) Rest/Conversation. Observation reveals that seat occupation of each type users depends on spatial factors. The relationship between the activity in the cafe and the spatial factor were quantitatively clarified by a multiple logistic regression analysis. As a result of the analysis, it was found that spatial factors such as “Distance from entrance/stairway to the seat”, ”Seat against a wall or not” and ”Types of Tables” are related to the activities in the cafe. While Output-based working type prefers to select multiple floor without the cash register, Rest/communication type prefers to select multiple Floor with the cash register. While Input-based working users prefer to select seats against a wall, Rest/ communication users tend to avoid the seat against a wall. Output-based and Input-based working users tend to select shared tables rather than the large table. The low tables were selected more by Input-based working users than by Output-based working users. Rest/ communication users tend to select large tables, not counters and shared tables.

The purpose of this study is to analyze the patterns of complicated pedestrian flow with visible pedestrian area model. The coordinates of all pedestrians at each frame is calculated.The pedestrian area is defined as the 90cm circle from the coordinates of each pedestrian. The condition of monodirectional pedestrians which forms groups is similar to the distribution of electric field, so Blobs, Meta-ball, with Bezier Clipping method is used to visualize the pedestrian area. (1) The conflict among pedestrians is reduced by the forming group of monodirectional pedestrians; (2) The pedestrian move along the edge of other group's area because he/she can't cross inside the group; (3) The overlap of group's area illustrates the conflict between groups;The condition of pedestrian flow is analyzed with visible pedestrian area model.

&nbsp;Recently, enrollments in nursery schools have become higher and higher. This is largely due to the social progress of women, with the increasing number of working mothers. Additionally, the number of three-generation households is decreasing. Nursery schools are traditionally low-rise structures, with a playground, but deregulation of the law now allows for the placement of nursery schools in middle floors of high-rise buildings. In Japan, the ages of nursery school students are generally from infancy to five-years old, which means that they can't evacuate the premises by themselves during a fire, so we must research ways to evacuate them safely. And the scheme of planning safe evacuations from buildings has not been sufficiently researched, so we have investigated the practice of fire drills and have interviewed teachers and students of nursery schools. The following is what we have learned:<br>&nbsp;(1)Characteristics of evacuation ;drills of nursery schools: Students evacuate in class groups, lead by their teachers, who provide the indications. Time is needed for evacuation preparation (setting up strollers, gathering infants and preparing to carry them out, and giving instructions regarding exiting, etc., ) and before starting evacuation, and time for confirming the numbers of students, and waiting time is needed when they are evacuating, so these times must be considered in the calculation of evacuation time.<br>&nbsp;(2)The characteristics of evacuation abilities of nursery school students : Infants (up to one-year old), and students who can't easily walk by themselves must be carried by a nurse or other adults, which makes evacuation movements and management after evacuation more manageable. Two-year-old students are able to walk alright on their own but cannot sufficiently grasp the situation. It's difficult to follow the teachers' instructions, so a lot of assistances are need. Children aged three and over can, of course, walk even better, and can grasp the severity of a fire. But they tend to walk more slowly as they feel frightened in cases when they are at earlier age, or they have to take an escape route that they are not familiar with. In order to shorten evacuation time, older students should evacuate first, as they can walk faster than younger students, thus their escape time won't be hindered by slower evacuees.<br>&nbsp;(3)Notes of buildings that include a nursery school: Regarding the situation of using stairways for evacuation, there are many points of concern regarding the safety of children. Because there are many dangerous points related to stairways, such as the fact that stairways often arouse fear in younger students during emergency evacuation, and as a result they walk more slowly. Consequently, older students try to pass the younger, slower students. Especially in cases when a nursery school is on a middle floor of a multi-use building, there is a possibility that confusion is caused among the evacuating children who walk slowly, along with their teachers, as evacuating people from other facilities mix with people evacuating from the nursery school. Thus, having a dedicated set of stairs for children is better. In addition, nursery schools that are in existing buildings that were not designed to accommodate nursery schools, have higher handles and the height of steps rise.<br>&nbsp;(4)Decreasing evacuation route length: Due to the fact that nursery school students' bodies and minds are not fully developed, their circumstances during a fire are more severe than those for adults. Thus, nursery schools should be on lower floors of buildings or should have their own buildings. Also the distance from the rooms to the temporary evacuation place should be as short as possible

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.

This case study examines the seat selection at the time of arrival in a small-scale non-territorial office. The questionnaire to the workers reveals that 23% of workers consider that their seat selections affect their business and 67% of workers prefer to change their seats to avoid other worker’s voice. The observation of the seat selection at the office shows that many workers tend to fix their own seats. Even when they miss the seats, they select another seat in the same area (table). Some particular areas are hardly used while the other areas are frequently selected. And the seats at the corner of each area are occupied first. Some workers select the area where the particular worker sit.

The purpose of this research was to explore the influence on user's behavior by conditions of location. The analysis of the cafe user as “The Third Place” can be understood by observation research. The Third Place proposed by Ray Oldenburg means originally the social surroundings separate from the two usual social environments of home and the workplace, but the cafe in Japan advertise as third place meaning private working spots. By grasping the influence on user's behavior in the cafe through not only the Third Place was mainly conversation proposed by Oldenburg but private working in the cafe, it was cleared that the conditions of location and the ratio of property have effect on actions of use as the Third Place.

This study analyzes the pedestrian's avoidance behavior in crossing flow in order to obtain quantitative criteria for evaluating the difficulty of walking in a crowd. The new graphic illustration methods, called Short-Time Pedestrian Path Diagram and Direction Rose Diagram, are developed and proposed in this paper to represent the state of a crowd visually. The result of our experiment suggests that pedestrians descend their walking speed or/and detour to avoid striking other people and each avoidance behavior can be classified into three levels, whose threshold are defined from the speed or the angular velocity of each pedestrian.
