  • The walkway level of service (LOS) is conceptualized using pedestrian flow rate, speed, and density according to the Korean Highway Capacity Manual (KHCM). However, as it is based on the data of commuters at peak hours, it needs to be reevaluated considering various trip purposes and a pleasant pedestrian environment. Thus, the authors aimed to investigate and analyze the characteristics of each group: pedestrians during the peak hour and those during the non-peak hour. Then they were verified statistically for the walkway evaluation criteria. In this study, the authors investigated pedestrian speed and flow in a complex transit center walkway with diverse trip purposes by peak and non-peak hour. Then the authors statistically verified the differences between the groups. A model was built for estimating pedestrian density by speed and flow; it was used to calculate the walkway capacity (67.3p/m/m) corresponding to LOS E. The authors established new criteria for LOS, applying the LOS from the HCM. These standards can then be used as the design standards for pedestrian walkways.

  • The purpose of in this paper is to estimate the capacity and to suggest the level of service for pedestrian walkway. To estimate the pedestrian walkway capacity, Pedestrian density and speed were collected at the walkways in the subway station and the sidewalks. The simple linear repression of pedestrian density and speed models were developed for the relationships between the pedestrian flow rate and the pedestrian speed. The analysis results are as follow : First. the ranges of capacity for walkway were found minimum 106p/m/m and maximum 126p/m/m. The capacity of walkway was suggested to 106p/m/m for 2001 KHCM. Second, it found that the range of the critical speeds were between 40m/minute and 43m/minute and the range of the critical densities were between 2.65 p/$m^2$ and 2.85 p/$m^2$. Third, the range of level of service are similar to that of the 2,000 US HCM. This study suggests that occupancy, density and speed at Los E use 0.38$m^2$/p, 2.6 p/$m^2$ and 40m/minute respectively.

  • A considerable amount of literature has been published on pedestrian LOS. So far, however, there is a limitation that LOS analysis methodologies has concentrated on quantitative variables such as pedestrian flow rate, speed and space. This paper intended to suggest the accessibility variable which can not be considered on previous study. The factor was defined and quantified using public transport attributes in particular. This study was carried out in three phases: 1. defined accessibility employing public mode location and service information. 2. investigated the relationship between accessibility and pedestrian flow rate 3. developed the model to establish the factors affected to pedestrian LOS. The results showed that accessibility, walkway attribute and land use type affected the pedestrian LOS. Especially, accessibility and commercial area ratio had negative relationship with LOS. Futhermore, pedestrian LOS declined when obstacle of bus station located on the walkway. On the contrary, LOS was upgraded when sufficient effective width or residential area was secured. These results can receive considerable critical attentions related to determination of pedestrian LOS or effective walkway width.

  • In the middle of motorization, the traffic problems become serious social problems in Korea. The walking environment is not only a topic which restores the community spirit of a city or society but also a lever which renovates the future space of the city environment-friendly. Thus, the Purpose of this study is to suggest the new criteria of walkway level of service adopting the concepts of safety. convenience, comfort, environment, security, and continuity in addition to present pedestrian flow rate, and to provide basic data for walkway plan in Korea. In order to analyze the adequacy of the present walkway level of service criteria, the walkways of which service levels were A, C, E according to USHCM were selected as study walkways, and an interview surrey was conducted to compare the three service levels with those that pedestrians evaluate actually. Also, another interview survey was conducted to analyze the service conditions and satisfaction level at the walkways of high service levels(A and B). For the establishment of more reasonable walkway level of service criteria. the survey of pedestrian\`s consciousness for walkway service was conducted. Based on the survey results, the new criteria for the evaluation of walkway service were selected and the six levels of service for each criterion was analyzed: so the comprehensive criteria of walkway level of service were suggested.

  • This study seeks to identify elements of spatial planning for areas surrounding children's parks in order to improve child safety. It will identify different aspects of child safety and extract elements of safety planning for the areas surrounding children's parks from a literature review of both domestic and international research. The study classifies the space between one's residence and the children's park as either a "means of access", such as pedestrian walkways and streets, or a "boundary", which consists of the entrance, exit, and fences; then, the derived safety planning elements were categorized in accordance with this classification. In order to ensure the validity of the planning elements, an expert survey was conducted of environment planners who specialize in the palnning and designing of residential area as well as government employees who are in direct charge of managing children's parks. The survey findings were as follow. First, the pedestrian walkway(means of access) near the park is the most crucial factor in regards to the safety of children, followed by the entrance and exit(boundary), fency(boundary), and streets (means of access), in descending order of importance. Thus, improving the safety of the pedestrian walkway should be considered first and foremost, and it should precede improving the surrounding streets. Second, an investigation of the need for safety devices near the children's park showed that securing visibility, through the installation of an illegal parking prevention device, is imperative. Illegal parking near children's parks poses a grave risk to pedestrian safety and demands immediate action. Furthermore, a section of streets within 300m of the park entrance should be designated as a children protection zone, in addition to the designation of school zones near elementary schools.

  • Campus core is an essential element in a university's physical environment for symbolic importance of high educational philosophy as well as hierarchical significance of campus structure. Yet, as modern expansion develops into and out of campus core, a challenging design and planning problem for a growing university is how to integrate a new development into the existing core structure and how to expand the fast-growing development beyond the core while maintaining a symbiotic harmony between the campus core and the modern expansion. Such challenge addresses four design frameworks for symbiotic development of the campus core and the modern expansion: (1) building grouping with territorial proximity; (2) building design rules for form and texture; (3) open space network with pedestrian walkway; (4) use-programming for on-campus student community. This study aims to explore these issues with in-depth case study of the Princeton University campus in Princeton, New Jersey in the United States. The study concludes that the Princeton campus is a result from successful synthesis of all the complex design elements, especially in relationship between the old and the new; and adds further that the development of a modern university campus requires a comprehensive plan that takes into account the older buildings when conceiving the new in symbiotic relationship along with open space network as well as functional program distribution.

  • Unsatisfactory urban walking environment stresses urban residents, and may cause mental illness and chronic diseases by reducing walking activities. Therefore, establishing a high-quality walking environment that can promote walking activities in urban residents has emerged as an important issue. The walking environment consists of various components, such as trees, stairs, streetlights, benches, signs, fences, and facilities, and it is essential to understand which components and their settings act as satisfiers or dissatisfiers for pedestrians, to create a better quality walking environment. Therefore, this study investigated pedestrian satisfaction and dissatisfaction as a function of various environmental components through a survey using walking environment images. The results revealed that most of the walking environment components except the braille block and treezone exhibited significant correlations with pedestrian satisfaction. Particularly, safety-related component (e.g., adjacent roads, parked cars, traffic cushions, and car separation), and landscape-related components (e.g., trees and green), as well as the material settings of landscape facilities (e.g., wooden fences, benches, stairs, and walkway surfaces) correlated with pedestrian satisfaction. The results of this study can contribute to the extraction of useful features to evaluate pedestrian satisfaction as a function of the walking environment. The research outcome is expected to assist in the effective arrangement of walking environment components and their settings, which will ultimately contribute to significantly satisfactory walking environment and encourage walking activities.

  • This study describes an improved model for estimating pedestrian LOS (Level of Service) by utilizing the space occupied by pedestrians. The method introduced the concept of conflict along the bi-directional pedestrian flow which enables calculating conflict area and average travel time in walking. Especially, the method incorporates the idea of generalized density concept which can consider effective walking area and pedestrian flow rates that might vary during the analysis period. After establishing methodology, adjustments of pedestrian LOS criteria in term of walking space occupied by pedestrians were performed. As a result, walking-occupied space at capacity level is 0.68 and corresponding pedestrian flow rate was calculated as 80 persons/min/m, while different pedestrian-occupied spaces were ordered to classify LOS at the points where the gradient changes. Furthermore, the statistical verification of service levels has shown that there is significant difference among all LOS categories at 5% significance level.

  • The paper analyzes factors to affect pedestrian volumes by land-use type using 2012 Seoul Pedestrian Survey. First of all, five groups were classified based on land-use types around survey points such as residential, commercial, industrial and green uses, using k-average cluster analysis. Then, differences in average pedestrian volumes by group were compared for a day and time of day. In addition, multiple regression analysis was employed to identify factors to affect pedestrian volumes, considering physical features, land use types, public transportation accessibility, and socio-economic indices as independent variables by spatial hierarchy. Model results show that the walkway width positively influenced on pedestrian volumes for all groups, whereas other variables differently affected by group. Our results can be used as basic data for establishing polices with respect to pedestrian road design and improvement as well as estimating pedestrian demand by land-use type.

  • Abeno Harukas is the tallest building in Japan and is located in Abeno, which is one of the three main railway transport nodes in Osaka. This building has a height of 300 meters, and its lowest levels are 30 meters below ground. It contains a department store, museum, offices, a hotel, and an observatory. In this urban renewal project, a section of the department store that encloses the station was dismantled and replaced by a supertall building complex, while infrastructure was simultaneously constructed, including: upgrades to the station and the existing department store, improved connections to the subway and pedestrian bridges, and a new pedestrian walkway over the road. In this paper, the ingenious erection processes, newly developed technologies, and precise construction management techniques are introduced for Japan's tallest building.
