PURPOSES : In this study, the propriety of expansion joint spacing of airport concrete pavement was examined by using weather and material characteristics. METHODS : A finite element model for simulating airport concrete pavement was developed and blowup occurrence due to temperature increase was analyzed. The critical temperature causing the expansion of concrete slab and blow up at the expansion joint was calculated according to the initial vertical displacement at the joint. The amount of expansion that can occur in the concrete slab for 20 years of design life was calculated by summing the expansion and contraction by temperature, alkali-silica reaction, and drying shrinkage. The effective expansion of pavement section between adjacent expansion joints was calculated by subtracting the effective width of expansion joint from the summation of the expansion of the pavement section. The temperature change causing the effective expansion of pavement section was also calculated. The effective expansion equivalent temperature change was compared to the critical temperature, which causes the blowup, according to expansion joint spacing to verify the propriety of expansion joint applied to the airport concrete pavement. RESULTS : When an initial vertical displacement of the expansion joint was 3mm or less, the blowup never occurred for 300m of joint spacing which is used in Korean airports currently. But, there was a risk of blow-up when an initial vertical displacement of the expansion joint was 5mm or more due to the weather or material characteristics. CONCLUSIONS : It was confirmed that the intial vertical displacement at the expansion joint could be managed below 3mm from the previous research results. Accordingly it was concluded that the 300m of current expansion joint spacing of Korean airports could be used without blowup by controling the alkali-silica reaction below its allowable limit.

This paper presents a new airport slot allocation model that uses AIP model to balance the use of airport slots within existing capacity based on the limitation of capacity expansion of airport slots. This new model is called a 'balanced airport slot allocation model', which integrates the airport facility usage system, which is applied independently without linkage, with the airport slot allocation system, introducing the market logical characteristic of 'administered incentive pricing. In this paper, we propose a new proposal to dramatically change the airport slot allocation system in the current situation where the expansion of facilities is limited in the urgent problem of the airport slot shortage, and it is necessary to balance the airport slot allocation. Airline paying for the use of an airport slot can determine the slot of the desired time slot based on the costs incurred by differentiating in the new airport slot allocation model. This is a system that allows the airlines that are willing to pay a lot of money in the market to use preferred airport slots.

In this study, we reviewed access transportation, operating companies, and airport infrastructure to revitalize Cheongju International Airport. Regarding access transportation infrastructure, it is necessary to promote a railway network connecting the metropolitan inland line and the central inland region. In addition, active administrative support from local governments is required to ensure smooth progress in railway and highway infrastructure linkage projects, such as the Osong Connecting Line and Chungbuk Line, high-speed rail network promotion, and expansion of the Chungbuk Eastern Axis Expressway and Central Expressway. Regarding operator access infrastructure, continuous efforts are required to add and attract airlines based at Cheongju International Airport. Regarding airport infrastructure, the Cheongju International Airport runway needs complete resurfacing due to its deterioration. Domestic passenger capacity has exceeded 6.5%, and considering the increase in import and export of high value-added goods in the North Chungcheong region, it is necessary to build and expand passenger terminals and cargo terminals. Cheongju International Airport's runway does not have enough runway length to operate large and ultra-large aircraft, so if it is extended from the existing 2,744m to 456m to 3,200m, several benefits can be expected in terms of revitalizing Cheongju Airport, such as route expansion.

Busan Gimhae Airport is a major airline base in Busan Gyeongnam and is close to Busan Harbor, With close the five largest ports in the world, GimHae has not been developed to fit the size and role of the port. Currently, there is an increasing number of flights and airline companies in use, but it is already foreseen that the airport has become a saturating airport and a military airport. Therefore, the lack of awareness of the importance of GimHae Airport and the lack of routes for airlines are a problem for KimHae Airport. This study considers the reduction of logistics cost and time due to the expansion of the international airport by anticipating the development of Busan International Airport centered on the ship supplies logistics based on the present point of time and the development plan of Busan Kimhae Airport. In addition, we review the priority of major air routes based on prefabricated logistics, and examine the contributions to the port logistics industry in Busan.

In China, the government has aggressively led the construction and expansion of airports across China. Upon this opportunity, "Korea-China" network is expected to expand. Therefore this study tried to deduce implications for Incheon International Airport by expansion of "Korea-China" traffic rights. As a result of analyzing the exchange values of traffic rights on the "Incheon~Beijing/Chengdu" routes, it was found that there is a concern that Chinese airlines could make inroads into Korean airline's market. In both routes, Korean airline's market share and passenger demand increased while the sales decreased after expanding traffic rights. On the other hand, Chinese airlines showed an increase in sales and a larger passenger growth than Korean airlines. Therefore it is necessary for the government to expand the traffic rights through detailed route value analysis.

This study deals with capacity expansion planning of airport infrastructure in view of economic validation that reflect construction costs and social benefits according to the reduction of passengers' delay time. We first forecast the airport peak-demand which has a seasonal and cyclical feature with ARIMA model that has been one of the most widely used linear models in time series forecasting. A discrete event simulation model is built for estimating actual delay time of passengers that consider the passenger's dynamic flow within airport infrastructure after arriving at the airport. With the trade-off relationship between cost and benefit, we determine an economic quantity of conveyor that will be expanded. Through the experiment performed with the case study of Incheon international airport, we demonstrate that our approach can be an effective method to solve the airport expansion problem with seasonal passenger arrival and dynamic operational aspects in airport infrastructure.

This study seeks to clarify the background and factors for the expansion of bus networks that connect Incheon International Airport with its hinterlands. For this research objective, this paper analyzes the relationships among the change of bus routes, competitive transportation modes, passenger fares, and the shortest time distance. Previously, the hinterlands of route bus networks that connect Gimpo International Airport were Seoul metropolitan area, Chungcheong region, Jeonju and Iksan in Jeollabuk-do(province). However, the opening of Incheon International Airport resulted in the expansion of the hinterlands of bus networks to Gangwon-do, Gwangju, and major cities in Youngnam region. Simultaneously, route bus networks also expanded in Seoul metropolitan area. Each bus route connecting Incheon International Airport with its hinterlands was opened by a single bus company or various bus companies. In many cases, due to the uncertainty of revenues or bus company's regional ties, a bus route was opened by various bus companies. In this paper, the analysis of the number of one-way route bus service and density of flight passengers shows that the frequency of the route bus service for Seoul except Gangseo-gu(ward) and for Seoul's satellite cities(Suwon, Seongnam, Anyang, Gunpo, Guri, and Osan) should be decreased. The analysis also shows that the frequency of the route bus services for the other cities, counties(Guns), and wards(gus) should be increased. In Seoul metropolitan area, although route bus fares are more expensive than subway fares, passengers use route bus more frequency than subway because time distance of route bus is shorter than that of subway and subway transfer is inconvenient. In general, outside Seoul metropolitan area, air flight is preferred in the regions that have airports. In contrast, the route bus is preferred in Daegu and other regions that do not have airports.

The capacity of Jeju International Airport has reached its limit due to a surge in air traffic demand such as passengers and cargo and the continuous expansion of Low Cost Carriers (LCC). Despite COVID-19 that has began in November 2019, Jeju International Airport still has continuous demand in terms of passenger and cargo transportation. As a result, it is undeniable that the delay rate also unexpectedly increased as the air traffic volume at Jeju International Airport continued to increase. In this study, the correlation between Turnaround Time and delay rates of national airlines is analyzed based on past flight data at Jeju International Airport, and the cumulative delay time trend for sampled airlines is compared with Turnaround Time. Through this study, it is expected to contribute to securing aircraft operation efficiency and on-time by analyzing delays related to Turnaround Time at Jeju International Airport.
