The old city centers of local metropolitans have lost their functions as CBD in korea. Those old city centers have an only role as a gate connected to the new CBD. This study aims to present regeneration stratigies of old city centers through Osaka case study. This research has been focused on the physical and environmental factors in urban regeneration. There are 4 strategies for old city centers. First, the strategy to attract people to the old city centers is high-density and mixed-use development having functions like shopping, entertainment, residence. This kind of development makes local metropolitan cities compact cities to protect urban sprawl. Second, strategy to give old city centers an identity is to conserve traditional culture and structures and to revitalize retail market. Third is to make pedestrian-friendly street system. Osaka ism't pedestrian friendly but remodelling the connect the pedestrian path to the culture facilities. Fourth is to have water and green environment. Green space is the strong factor that pull people to old city centers.

Currently, big data and open data, together with traditional measured data, have come to constitute a new data environment, expanding new technical paths for quantitative analysis of the street environment. Streets provide precious linear public space in high-density residential areas. Pedestrian activities are the main body of street vitality. In this paper, 441 street segments were selected from 21 residential districts in high-density downtown area of Shanghai as cases, to quantitatively evaluate the influencing factors of pedestrian activities. Bivariate analysis was performed, and the results showed that street vitality was not only correlated with a highly populated environment, but also with other factors. In particular, the density of entrances and exits of residential properties, the proportion of walkable areas, and the density of retail and service facilities, were correlated with the vitality of street segments. The magnitudes of correlation between the street environmental factors and the pedestrian traffic differed across various trip purposes. Segment connectivity factors were more correlated with walking for leisure than for transportation. While public transportation factors were mainly correlated with walking for transportation, vehicular traffic factors were negatively correlated with walking for leisure.

Despite the legal and institutional measures that have been enacted for the safety management of school facilities, the number of school accidents has continued to rise, particularly in regards to the number of accidents related to schools. However, school facilities have had a difficult time creating safe school environments for the school administration and local governments. This is due to the fact that the Office of Education and the Ministry of Education, not the school or educational offices, have insufficient institutional devices such as standards and systems for the promotion of safe school environments. This study attempted to confirm the direction of the improvement of the safety of school facilities. To this end, four safety assessment topics (separation of pedestrians, pedestrian path management, pedestrian visibility, and surrounding risk factors) were derived based on the surveyed data for the safety of the external environment of domestic and international school facilities. 179 school facilities nationwide (kindergartens, elementary schools, middle schools, high schools, and special schools) were analyzed for current cases of accidents that occurred mainly on school roads. Roughly 50% of the analyzed evaluation scores showed that it is necessary to improve the external environment of school facilities.

The purpose of this study is to suggest a scheme to provide children safer and more comfortable walking circumstances by survey current walking circumstances of schoolzone ways. A scheme suggested in this study was based on the analysis of survey to elementary school in 3 Newtowns(Dongtan, Dongbaek and Gumdan City) and actually surveyed data on school zone, the scheme can be summed up as follows; First, to avoid pedestrian roads being interrupted and to expend waiting space near schoolzone ways, several measures are needed including fixing roads and building additional gateway. Second, pedestrian crossings in front of school gate should be located at least 30m away from the left side of the gate. Third, to secure pedestrians' safety in school zone ways should be planed and established more security concepts und facilities.

Roundabouts have been operated in Europe, America and Australia since the 1970s, and many relevant researches continually was carried out. Though many studies regarding roundabout have been recently conducted in korea, most of them have focused on its operational safety and efficiency. Moreover, roundabout design guideline did not define a clear criteria related to pedestrian in roundabout, but seldom investigate the influences of pedestrian on crosswalk. In this study, we seek ways to operate the pedestrian crosswalk signal on roundabout maximizing their operational effects in exceptional case such as rush hour or intersection near the special facilities. We proved that roundabout signal operation is effective under certain circumstances in according to the number of pedestrian, and suggested the optimal signal timing plan for signalized roundabouts. For pursuing the above, we conducted the simulation test using the VISSIM model. The results show that the operational effectiveness of signalized roundabout was evaluated to be better than non-signalized roundabout in specific pedestrian volume condition. In addition, those results are confirmed using simulation analysis conducted on the real roundabout.

South Korea has achieved economic development rapidly during last 50 years. However, such fast economic development with industrialization caused skyrocketing increase of automobiles. The increase of automobile has created various problems in the cities. Problems like traffic congestion and accident, environmental pollution, noise, and vibration have done human beings, who are the principal agents harm. They have made citizens understand how important Green transportation, especially pedestrian movement, is. Recently, installation of pedestrian facilities has been expanded. If walking facilities are incorrectly designed, they can create inconvenience, danger and the state of emergency due to the lack of safety and pleasant feelings. However, since the importance of the facility designs has been neglected due to the lack of understanding, it is hard to improve the facilities. Therefore, we need various studies of walking simulation in order to research the designs for pedestrians' safety and convenience. The objective of this study is to analyze the pedestrians' behavior and movement in a transfer subway station. The improvement of walking environment was made after chasing and analyzing the pedestrians' movement which is investigated in the actual field using SimWalk simulation program.

This article analyzes the obtained data on consciousness survey of disabled and non-disabled pedestrians, and proposes fundamental data for public strategy in order to enhance facilities in subway stations in advance. This paper conduct literature review, new listing survey related to 'The Code for Improvement of Convenience for Moving Vulnerable Pedestrians', and Modified-Importance-Performance Analysis (M-IPA). The results show that disabled pedestrians want enhancement in information facilities as a whole. In addition, the results show that several improvements needs to be applied to accessible sidewalk, to informative notification, to alarm and evacuation system and to toilet for disabled pedestrians. This indicates that disabled pedestrians heavily concentrate on accessibility to subway station and provided information compared with disabled pedestrians.

Cityschumers experience the urban with the visual perception while walking an average speed of 4km per hour. At this time, recognition of the color field accounts for more than 70%. Therefore, in this paper the environmental color of urban street is examined by dividing the pedestrian visual field area. In the urban street, the area of the visual field area of the pedestrian is divided into Ground Plane, Roadside, Canopy and Building Wall. In addition, we observe and color survey the environmental color of Exhibition Road, which is the northern side space of South Kensington in London, which adopted the world's first shared space. The color of the visual filed area was dominated as YR, GY, Y, PB. The Ground Pland was dominated by the YR. The reason for this is that the color of the floor has changed due to the shadows of surrounding architecture and facilities. Roadside was dominated in various ways such as GY, BG, PB, B and P. Canopy was mainly composed of PB, GY, etc. It was found that the material color of the lower part of the architecture was reflected. The architecture wall was affected by the reflectance and absorption rate of the transparent material. The first image that comes to mind when thinking about the urban is the street where pedestrians walk, feel and enjoy themselves. Therefore, it is suggested that various policy frameworks for managing and managing urban planning professionals may be different from the perceptions of pedestrians active in mega cities.
