  • Kimpo international airport logistics complex had been the most busiest airfreight gateway in Korea during last century but, after the grand open of Incheon international airport in 2001, it had lost its major role as a national airfreight hub facilities. However, owing to its locational advantages in Seoul metropolitan area. Kimpo airport logistics park still acts like an urban logistics distribution center in these days. Caused by the KAC's profit oriented policies, the Kimpo airport logistics park's public function as an urban distribution center might be curtailed in the future. Therefore, several laws and ordinances related to national and regional logistics strategies should be modified to prevent it.

  • Airport railroad have required maximum design speed 120km/h and wind speed 50m/s condition as design item of airport railroad vehicles. To design and manufacture the vehicle satisfying these conditions, it must carry out the dynamic behaviors analysis such as hunting stability, ride comfort derailment ratio, unloading ratio and lateral force to meet the criterion described in Urban Railroad Act. Dynamic behaviors of vehicle have carried out using the multi-body dynamics simulation program(VAMPIRE). This paper presents the evaluation methods and criterion used to verify dynamic performance of airport railroad vehicle, and show the analysis results of vehicle dynamic simulation and the test results for vibration and ride comfort measured on running performance tests. As a results, each analysis results and test results meet the criterion described in Urban Railroad Act.

  • According to the statistics of the Ministry of Land Transport and Transportation in 2018, the average annual average number of air traffic users for has increased by 5.07% for domestic flights and 8.84% for international flights. Korea is facing a steady rise in demand from foreign tourists due to the Korean Wave. At the same time, a new lifestyle that values the quality of life of individuals is taking root, along with the emergence of LCC, and Korean tourists' overseas tours are also increasing, so improvement and expansion of domestic airport passenger terminals is urgently needed. it is important to develop a structured airport infrastructure by making efficient and accurate forecasts of aviation demand. in this study, based on the Big Data, long-term domestic and international demand forecasts for urban airports were conducted.. Domestic flights will see a decrease in the number of airport passengers after 2028, and international flights will continue to increase. It is imperative to improve and expand passenger terminals at domestic airports.

  • The main purpose of this study is to analysis of urban MAGLEV vehicle for the Incheon International Airport Maglev railway, in the process of construction at the moment, in Korea. For analysis of urban MAGLEV, we have measurement power a special quality of MAGLEV operating the center science museum in Deajeon. 1) The power property related to urban MAGLEV vehicle demand on the Incheon International Airport Maglev railway track and substation capacity compared to the result given. 2) The optimum design of substation is determined based on the analysis. 3) The equipments of substation are determined based on the analysis. The result of measurement performance, therefore, enables us to reflect the good property, to the power supply design. The result of research performance, therefore, enables us to reflect the Power Supply System design for the stabilized and economized MAGLEV operation.

  • Characteristics of urban wanning phenomenon were studied using degree days for three big cities(Seoul, Busan, Daegu) adjacent to airport. Time variation of the cooling and heating degree days was analyzed using the daily mean air temperature data measured at the six meteorological observatory for long-term periods(25~43years). The results for the big cities are as followings: 1) It was found that the heating degree days trended to decrease from year to year. 2) The cooling degree days were nearly unchanged during the same analysis periods. 3) The number of days calling for air-heating also tended to decrease as time passes. 4) Those of air-cooling were nearly unchanged during the same time. It suggests that the change of air-heating condition owing to urbanization came in evidence in the winter season, but that of air-cooling condition was slight in the summer season. On the other hand, the long-term trends of degree days were very small in airport areas except for Kimhae airport. Hence, the gaps of degree days between big cities and rural airport areas are increasing.

  • The main purpose of this paper is to suggest a spatial planning approach to effectively deal with airport noise problems in neighborhoods adjacent to civil airports. Rapid urbanization around the airports, as well as growing concerns on quality-of-life, resulted in ever-growing airport noise complaints, lawsuit, and central government's financial burden. S. Korea government adopted a restriction- and compensation-based airport noise management policy against the problems in mid 1990s. It, however, turns out to be ineffective in guiding incompatible land uses and facilities away from the airports' environs and to encourage compatible ones to locate around the airports. Base on the United State's and United Kingdom's airport noise management practices, therefore, this study suggests a new spatial planning approach that emphasizes the following: 1) diversification of current airport noise mitigation programs, 2) introduction of "sector"-based, spatial management system, and 3) central government's close cooperation with local governments and communities.

  • Reliable fast working maglev switch is one of the key technologies needed for the maglev system to be commercialized. Switch for the maglev system is large, heavy, complicated, expensive compared with that of the traditional wheel-on-rail system. This paper reports the development of a segmented maglev switch for urban transit maglev system under construction for the 6.1 km long double track maglev commercialization line in Inchon international airport in 2012. Test results along with details of the segmented maglev switch components are reported.

  • We have established a wind map of Singapore, a city-state characterized its land cover by urban buildings to confirm a possibility of wind farm development. As a simple but useful approximation of urban canopy, a zero-plane displacement concept was employed. The territory is divided into 15 sectors having similar urban building layouts, and zero-plane displacement, equivalent roughness height at each sector was calculated to setup a terrain boundary condition. Annual mean wind speed and mean wind power density map were drawn by a CFD micrositing model, WindSim where Changi International Airport wind data was used as an in-situ measurement. Unfortunately, predicted wind power density does not exceed 80 $W/m^2$ at 50 m above ground level which would not sufficient for wind power generation. However, the established Singapore wind map is expected to be applied for wind environment assessment and urban planning purpose.

  • This paper evaluates and maps the quality of life in the Atlanta, Georgia metropolitan area in 2000. Three environmental variables from Landsat TM data, four socioeconomic variables from census data, and a hazard-related variable from toxic release inventory (TRI) database were integrated into a geographic information system (GIS) environment for the quality of life assessment. To solve the incompatibility problem in areal units among different data, the four socioeconomic variables aggregated by zonal units were spatially disaggregated into individual pixels. Principal components analysis (PCA) was employed to integrate and transform environmental, socioeconomic, and hazard-related variables into a resultant quality of life score for each pixel. Results indicate that the highest quality of life score was found around Sandy Springs, Roswell, Alphretta, and the northern parts of Fulton County along Georgia 400 whereas the lowest quality of life score was clustered around Smyma of Cobb County, the inner city of Atlanta, and Hartsfield-Jackson International Airport. The results also reveals that normalized difference vegetation index (NDVI) and relative risk from TRI facilities are two versatile indicators of environmental and socioeconomic quality of an urban area in the United States.
