Recently, the interest in the mixed-use development of various urban planning facilities has been increased, but the interest in the Mixed-use development of bus depots that is closely related to our daily life is insufficient circumstance so far. Accordingly, this study aims to realize the necessity for the mixed-use development of bus depots as methods to improve the living environment and use efficiently the land, and to suggest reasonable development directions by analyzing their physical character after classifying bus depots according to their position in the residential area. As the results of study, bus depots have different properties according to their position in residential area and have the problem of space shortage. Also, many things such as location of entrances, the finish method of edge of bus depot's area are affected by the surrounding environment. So development plan to consider the each condition is required.

본 연구는 대중교통 특히, 버스의 이용과정에서 이용자가 받는 외부 자극(이용환경)이 스트레스(육체적 정신적 부하)에 미치는 영향관계를 분석하였다. 이를 위해 요인분석 및 구조방정식모형(Structural Equation Model)을 이용하였으며, 대전 시내버스 이용자를 대상으로 자료를 수집하였다. 분석결과, 5개 변수 중 탑승혼잡요인이 버스 이용자의 스트레스에 가장 큰 영향을 주는 요인인 것으로 나타났으며(${\beta}=.416$), 다음으로 환승요인(${\beta}=.392$), 운영요인(${\beta}=.265$), 계절요인(${\beta}=.150$), 정류장시설요인(${\beta}=.090$)의 순으로 나타났다. 즉, 이용자의 스트레스는 시설과 운영의 양적인 요인보다는 질적인 서비스 수준 더 큰 관련성이 있는 것으로 분석된 바, 버스정책은 이용자 중심으로 전환되어야 할 것이다. 또한, 스트레스는 이용자특성(성별, 연령, 정기이용여부)에 따라 다르게 나타나므로 보다 세분화된 서비스 제고전략이 유효할 것으로 판단된다.

The use of bus stop in the center lane has reduced the emissions of exhaust gas on the road due to the improvement of the traffic speed but has caused a health problem for the citizens who are waiting for the bus in the platform, and thus the air pollution control of bus stop in the center lane is emerging as a more important part. This study was conducted to investigate the air pollution degree for the center lane-bus stops in four regions using mobile air measuring vehicle, and to evaluate the characteristics of air pollution by comparing with the data measured at the urban air monitoring site close to the bus stops. In addition, the correlation analysis was performed to analyze the impact to neighboring region by vehicle exhaust gas. The regional mean concentration of nitrogen dioxide in the center lane-bus stops ranged from 0.025 to 0.043 ppm which shows from 2.5 times to 5.3 times higher than the values of urban air monitoring site selected as a control group. The regional mean concentration of ozone in the center lane-bus stops ranged from 0.023 to 0.034 ppm which shows from 3% to 28% lower than the values of urban air monitoring site selected as a control group. The concentrations of nitrogen dioxide and ozone for the sampling regions did not exceed one hour-air quality environmental standard (0.1 ppm). The mean concentration of particulate matter for four center lane-bus stops was $28{\mu}g/m^3$ which shows about 27% higher than the values of urban air monitoring site selected as a control group, and that of particulate matter did not exceed one day-air quality environmental standard ($100{\mu}g/m^3$). In the results of correlation analysis between data from center lane-bus stops and data from urban air monitoring sites, the correlation coefficient (r) of nitrogen dioxide was relatively low as 0.316 to 0.416, and the correlation coefficient was high as the distance was close and vice versa. However, the correlation coefficient of ozone ranged from 0.167 to 0.658 and the correlation coefficient was high as the distance was far and vice versa.

Bus station is a public space which many people use and various activities are occurred in urban life. Main activities are waiting for departure or passengers with the feelings of joys and sorrows. Also sound information including announcing message of arrival and departure are to be considered carefully. Considering these roles of bus station, creating acoustic amenity is a prerequisite to the spaces. In this study, the spaces of bus station were classified into 4 spaces such as approaching path, waiting palace, departure and arrival platform. Observation survey was conducted to extract various activities in the view point of sound in each space. And subjective response was analyzed before and after introducing prepared sounds.

There are about 38,977 CNG cars and 247 natural gas vehicle charging stations in operation in order to improve the urban air environment. With the introduction of natural gas vehicles, the atmospheric environment, which was the main cause of air pollution in the metropolitan area, was remarkably improved. However, unlike these positive effects, CNG bus accidents, which occurred more than 10 times since 2005, have caused concern among the majority of citizens using public transportation. It is necessary to make a judgment on the feasibility and future direction of CNG pressure vessel safety management that can safeguard the safety of CNG pressure vessel at the time of starting. In this study, we investigates production and use of CNG vessel, the current status of safety management of CNG bus transportation companies & charging stations and then proposes measures to prevent accident recurrence and safety management based on the actual situation investigation and analysis.

버스 정류장은 많은 승객이 이용하기 때문에 편리한 서비스 제공을 위하여 이용자 중심으로 환경을 개선할 필요가 있다. 본 연구는 GAP, IPA, 구조방정식을 이용한 버스 정류장 서비스 수준에 대한 이용자 평가모델 구축을 통하여 그 개선 방향을 제시하고자 하였다. 버스 정류장의 31개 서비스 항목에 대한 GAP 구축에서는 장애인 관련 시설, 버스 이용 관련 정보를 제공하는 항목에서 차이가 높게 나타났다. IPA의 현재 서비스의 경우는 버스 운행 관련 정보, 보조시설, 장애인 지원시설에서 우선 시정이 필요한 것으로 나타났고, 서비스 기대치의 경우는 버스 운행 관련 정보 및 환승시설, 장애인 지원시설에서 지속적 노력이 필요한 것으로 나타났다. 구조방정식에 의한 버스 정류장 서비스 평가모델은 적합도가 좋은 것으로 나타났으며, 버스 정류장 전체 만족도에는 시설 이용 만족보다는 대기 만족 그리고 버스 정류장 시설 이용 만족에는 버스 운행 관련 정보 만족, 보조시설 만족, 버스 운행 정보 및 환승시설, 장애인 지원시설이 상대적으로 영향을 많이 미치는 것으로 나타났다. 그리고 현재 버스 정류장에 대한 전체 만족도가 낮을수록, 전체 만족도에 대한 기대치가 높게 요구되고 있는 것으로 나타났다. 따라서 버스 운행 관련 정보와 장애인 지원시설에 대해서는 적극적인 개선 전략이 필요한 것으로 나타났다.

This study analyzed the characteristics of Physical Environment of existing free shuttle bus Interior centered on elderly people who frequently use free shuttle buses. The purpose of this study is to provide basic data that can be used for improvement of existing free shuttle buses. In the case of the old type, in terms of accessible design, the middle entrance is not normally opened except the wheelchair occupant, so that the entrance of the front wheel is always used. Therefore, most elderly people go to the back seat and travel distance is twice longer. In addition, many stairs caused frequent inconveniences for boarding. In the case of the new type, it is planned to be a low-floor type, and various types of safety rods and handles, pictograms for enhancing the information convenience are well-equipped, and the measured value of the overall design characteristic is high. However, in the case of mental stability, it was confirmed that the seat of the bus is colored with a cold color system and is in a different relationship with the warm color which can feel mental stability. Overall, both old and new shuttle buses lack audiovisual feedback on bus routes and route guidance in terms of Supportive design. Also, since the cleaning tools and other miscellaneous items were left in the room, it became an obstacle to space utilization in terms of adaptable design. In terms of safety, both shuttle buses did not come into view with fire extinguishers shaded by miscellaneous items. Therefore, immediate action is unlikely in case of emergency. This problem should be resolved quickly.
