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 this study is to estimate the perception of elderly residents on the residential environment improving projects and suggest the political implications. The survey include questionnaires about the importance and the satisfaction level on the project maintenance factors. The results were statistically analyzed by Importance-Performance Analysis (IPA). As the result of the study, firstly, it shows that 'the possible overkill area' on the IPA action grid includes none of factors except 'landscape' which is very similar to mean of performance score. the result of analysis means that the project is very efficient. Secondly, the policy is necessary to improve 'pedestrian passage', 'public open space' and 'transportation environment'. Considering elderly residents especially 'pedestrian passage' and 'public open space' are in need of improvement immediately. In detail 'traffic facility', building 'urban park' and 'pedestrian passage', 'paving of pedestrian passage', 'children's playground' are in need of improvement as well. The results of analysis on elderly and non-elderly residents of Yonnam project may be important foundation for future strategies for improvement.

In Korea, the number of elderly has been increasing rapidly. So it is also expected that the economic activity and the trip frequency of the elderly will increase. On the other hand, elderly related accidents such as falls during walking are steadily increasing and the satisfaction about pedestrian environment of elderly is very low. In this paper, we found one of the reasons for these dissatisfaction in pedestrian facility, which is not considering the walking ability (about 75% of non-elderly person) of the elderly. So, we analyze the kinematic walking characteristics of the elderly with the motion analysis system, when the elderly use stairs. As a result of analysis of various walking variables, the current standard for stairway height in Korean law (18cm) requires excessive force to elderly so it was difficult for elderly to keep the balance of the body in ascending and descending walk of stairs. In this paper, we propose the stair design criteria through the cluster analysis of walking parameters reflecting the gait characteristics of the elderly. This change is not a big for non-elderly person, but it can promote more socioeconomic activities for the elderly.

Although the urban elevated road is welcomed in modern society to deal with urban traffic problems, its negative influence on both the pedestrian environment and urban landscape has been frequently observed. Furthermore, the space under elevated structures has been ignored, being the lost space. Recently, several efforts have been devoted into bringing back the lostspace. However, any specific design guidelines shown in the street design of Japan and Singapore have not been suggested in Korea, yet. This study proposes a case of the Nengdong-Ro street design where the two-story urban elevated road is being constructed and negative effects of the elevated road are largely expected. One of the purposes of Nengdong-Ro street design proposed in this study is to relieve the negative effect os the two-story elevated road, and to provide a better pedestrian environment in Nengdong-Ro. The other purpose is to suggest general guidelines that can be applied to the similar context as Nengdong-Ro. It is considered that the space under the elevated road generally consist of three sections: 1) main section where the elevated road runs parallel with the ground, 2) landing section where elevated road goes down to the ground, and 3) facility section where facilities such as the platform and the ticketing booth are located. The design guidelines are suggested for each section, because each section has a different situation. Plans, section and elevations and the details of the street furniture are also incorporated to support the design guidelines.

The conflict of opposing pedestrian traffic-flow in a subway station(made up of stair, passageway, and escalator) diminishes the convenience and mobility of its users. In addition, the station's efficiency would be negatively affected by the growth of delay and queue length in pedestrian facilities. As these phenomena have been resulted by the overlapping in pedestrian's traffic-line, the separation of it would alleviate these problems. For the criteria and methodology of separation, this paper has investigated the bi-directional queue length and delay on the entrance of each facility (stair, passageway and escalator). Since the pedestrian flow exists bidirectionally, we have used the weighted average by inflow rate for the delay value. For the optimization of the separation, the Genetic Algorithm has been utilized in order to minimize the delay.

This research was undertaken to prove the relationship between street mall activation and architectural plan design. The research methodology was established based on the analysis of data of two existing street malls in Korea (Western Dome & LaFesta) and theoretical studies of outdoor space design. The findings from this study are the following: First, building blocks with segments in every 50m or so are ideal for detailed communication between visitors and building contents. Second, the ratio of width of main corridor and building height should be less than 1 to provide intimate feel and keep visitors' attention concentrated in the facility. Third, store unit should have more storefronts to be exposed more to passers-by and lead more pedestrian traffic. Fourth, shape of store unit would rather be wide and shallow, instead of narrow and deep, to have more exposure to the central corridor. Fifth, the building block of the busiest(most expensive) area that is usually at the main entrance area of street mall should be flexible to fit more smaller units to maximize the profitability. Sixth, the main entrance of store should face the main pedestrian corridor to induce the influx of visitors. Lastly seventh, anchor tenant that has strong name recognition is usually located on basement or higher level to induce pedestrian traffic into the mall, key tenants that are strong and familiar brand names should be located at the corner of building block with spacing to attract visitors, provide even distribution of traffic, and support wayfinding, and local tenant should be located at small units along the central corridor or remainder spaces occurred from building core layout.

The Design manual for adjusting the capacity and LOS of facilities has been shared in urban railways and high-speed railway stations. However, the pattern of urban railways users and those of high-speed railway users are different from each other. For an example, the high-speed railway users tend to carry voluminous luggages and the transportation disadvantaged such as children and the elderlies. Accordingly, we see that the scale of facilities and the station itself should be constructed differently. The transfer facilities in the high-speed railway stations are classified widely into walking assisting facilities and convenient facilities. We invented the concept of PME (Pedestrian Moving Equivalent) and PWE (Pedestrian Waiting Equivalent)for the spatial calculation of those who are with wheeled luggages, back packs, and children to reflect the uniqueness of users in high-speed railway stations. These equivalents have been applied to the design of the facilities to asses the new Capacity and LOS that are users' favored.

Recently the passenger of railway satisfaction levels are lowered. the reason why the railway station was built without considering the increased passenger due to diversification(transfer, shopping, and etc.) of the domestic railway station infrastructure. Especially, in case of KTX Gwangju-Songjeong Station, the number of its passenger has been increased about more than three times since its opening in 2015, so that there are much inconvenience generated in the station congested with passengers. his study aims to excute using Pedestrian simulation and Design Hourly Factor concepts of Highway Engineering, in order to designing the optimum area through the passenger demand forecast for each station. For this analysis was divided into the second stage. Frist, the railway passenger was calculated by using the methodology of Design Hourly Factor that is used during road design in the aspect of traffic engineering. Second, we tried to analyze the level of service in each railway station facility through the pedestrian simulation. Analytical results show that utilizing pedestrian simulation provides verification for calculation of LOS of each railway station facility. Therefore, In the future when designing railway station of facilities will be possible to suggest the facilities area based on LOS.
