The government continues to make efforts to improve effectiveness, integration and connectivity of public transportation systems. But there have been only a few studies about it. This paper addresses the quality evaluation of pedestrian facility service in transfer stations at urban railroad. LOS (Level Of Service) model of urban railroad by facility based on the body ellipse and density recalculated considering the recent Korean body standard and the suggested Pedestrian Moving Equivalent (PME) and Pedestrian Waiting Equivalent (PWE). For LOS model for the ticket booths and ticket vending machines, queuing theory has been applied to determine LOS of Pedestrians. And the importance weights among the pedestrian facilities is obtained by applying AHP analysis. Lastly, this paper shows and discusses the evaluation results of overall LOS of pedestrian facilities of five urban railroad transfer stations in Seoul.

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.

Currently, level of service(LOS) analysis methods for pedestrian sidewalks are provided in Korean Highway Capacity Manual(KHCM, 2013). However, conventional methods provided in the KHCM produce most of pedestrian sidewalks' LOS as level A, indicating that existing analysis methods are unable to reflect realistic pedestrian sidewalks' LOS. The objectives of this research are to identify the suitability of current LOS criteria and to propose improved LOS evaluation criteria and methods with pedestrian volume data carried out for 10,000 sites in 2009. This research proposes new criteria by using the qualitative definition of LOS proposed by Fruin and Hall, new standard Korean human scale and new criteria of pedestrian occupancy space. Application results of new criteria show that more realistic results can be achieved than the existing methods. It is expected that applying the newly developed criteria and methods can make planning, design and construction of pedestrian sidewalks more realistic and various.

Recently, the importance of monitoring and management measures for bicycle road related facilities has been increasing. However, research on the monitoring and evaluation of users' safety and convenience in walking spaces including bicycle path is insufficient. In this study, we would like to construct health monitoring data for cylists-pedestrians mixed road using a mobile mapping system, and propose a plan to calculate the level of service of the mixed roads from the perspective of pedestrians and cyclists using artificial intelligence based object detection techniques. The monitoring and level of service calculation method of cylists-pedestrians mixed roads proposed in this study is expected to be used as basic information for planning and management such as maintenance and reconstruction of walking spaces in preparation for the increase of electric bicycles and personal mobility in the future.

최근 보행자 행태를 반영한 미시적 시뮬레이션 분석이 가능하게 되었다. 차량 분석과 유사하게 보행자 행태 중 가장 빈번히 사용되는 것은 보행속도로 이는 횡단보도 보행자 녹색시간 산정과도 매우 밀접한 관계가 있다. 또한 보도의 밀도를 산정함에 있어서 보행자 속도는 중요한 역할을 담당한다. 이에 본 논문에서는 횡단보도의 보행자 속도를 실측하고, 이를 기반으로 미시적 시뮬레이션인 VISSIM의 주요 파라메타인 보행속도를 이용하여 역삼역 일대의 보행실태를 점검해 보았다. 분석에 사용된 보행속도 실측자료는 서울시 16개 횡단보도에서 조사되었으며, 연령별로 일반인(64세 이하)과 노인(65세 이상)을 구분하여 분석하였다.

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.

최근 타 교통수단으로 인해 발생하는 교통사고나 환경오염 등의 문제들을 보완하는 녹색 교통수단의 하나로써 보행교통에 대한 관심과 연구가 활발하게 증가되고 있다. 하지만 차량교통에 관한 연구에 비해 보행 교통에 관한 연구는 미미하며, 특히 우리나라 여건에 맞는 보행 환경의 서비스 수준과 보행 안전도 등에 대한 객관적 평가 모형의 개발이 필요한 실정이다. 이에 본 연구에서는 도시 내 보행 환경 요소를 정량적으로 계산하고 측정할 수 있는 평가 지표인 그린 스코어(Green Score)를 개발하고자 하였다. 본 논문에서 제시한 그린 스코어 측정 모형은 실제 물리적인 보행공간을 기반으로 가상의 시스템에 적용되어 보행 이동 패턴의 가시화, 보행 환경의 쾌적성과 편의성 평가 예측에 활용될 수 있을 것이다.

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.

The Context-Awareness technology which can provide the appropriate information to the human after estimating a lot of information exceeds the time and space in the ubiquitous environment is being developed now. GIS (Geographic Information System) and LBS (Location Based Services) based context awareness is one of these kinds of technology. The context awareness based transfer guide service which can provide useful information, according to the different information which was got from different sensors which were set in different places, to the pedestrian who is using the transfer center will be introduced in this paper. About the result of the service prototype which was tested in test-bed, the context awareness information such as the inside location and density calculation's accuracy is 90%, and the response time of the service is in 10 seconds, and also, the reliability will be higher if more advanced based infra will be used, so it is consider that it can be used to provide service enough.

Currently our country has very serious problems of traffic congestion and urban environment due to increasing automobile ownership. Recently, our concern about environmentally sustainable transportation and green transportation is increasing, so the government is pushing ahead the policy of bicycle using activation. So it is needed to develop a model to analyze the service level of bicycle roads more realistically. In this study, a neuro-fuzzy inference model to analyze the service level of bicycle roads was built selecting the width of bicycle roads, the number of conflicts during cycling and pedestrian volume, which have fuzzy characteristics, as input variables. The predictability of the model was evaluated comparing the surveyed and the estimated. The values of the statistics, $R^2$, MAE and MSE were 0.987, 0.142, 0.032. Therefore, It may be judged that the explainability of the model is very high. The service levels of bicyle roads estimated by the model are 1~3 steps lower than KHCM assessments. The reason may be explained that the model estimates the service level considering the width of bicycle roads and the number of conflicts simultaneously besides pedestrian volume.
