The volume of transfer passengers now faces a crisis because the number of Chinese and Japanese passengers, the majority of transfer through Korea, is decreasing. This paper is analyzing the their air travel behaviors as well as characteristics of their transfer behaviors at airport. According to the research, it is suggested that transfer passengers perceive the importance of duty-free stores but their satisfaction of using duty-free stores during their transfer at Icheon airport was proven to be low. Considering the characteristics of transfer service quality at Incheon airport, waiting time of transfer is important but not satisfactory for them. Moreover, information of free transfer tour to city downtown and paid-in transfer tour for medical tourism is not known very well among North East Asian passengers. Thus, it is necessary to do detailed research of North East Asian transfer passengers, who have transferred through Incheon airport more than twice a year, to find out their exact needs of transfer tour in Korea.

The one of the necessary technologies to live in the ubiquitous society that we can exchange some informations whenever it is and wherever we are, is the technology of context-awareness. The technology of context-awareness can be used various fields-medical science, national defense, national security and etc. and the technology can affect our society by and large. The technology of context-awareness is also applicable to many fields in the urban transit. In this paper, we describe the present condition of the technology of context-awareness and the examples of practical application of it and suggest some plans that are applicable to build an intelligent surveillance system for urban transit. We can connect the operating officer who is in the nearest to the place where the some events happened within the urban transit service area through the intelligent surveillance system for urban transit and we can eel a foothold in perceiving automatically various events within urban transit service area. So, the technology of context-awareness is the basic technology to realize an intelligent surveillance for urban transit, for the security of passengers and the protection of facilities in urban transit.

This study investigates the diurnal pattern of transit ridership in the Metropolitan Seoul area. For the purpose, we use a weekday Smart Card passenger transaction data in 2005. Eleven passenger trip patterns are found from 2.74 million passengers moving on the Metropolitan Seoul Metro system. Among them, we analyze 2.4 million passengers blonging to five trip types having only one or two transaction record during a day. A total of 357 metro stations are classified to four types according to their diurnal pattern of passenger riderships. We analyze the relationships between passenger's trip chain patterns and subway station's diurnal transit ridership patterns. The result shows that the ratio of the number of passengers of particular time of the day is hierarchically related with trip chain patterns.

The carbody of the Korean Rubber Tired AGT is small size and light weight comparing to existing electric railcars. For this reasons, car shape and arrangement of major equipments are limited. AGT is newly adopted mass transportation system in Korea. Therfore, it should be desined to appeal to passengers and create new passenger demand. To achieve this goal, the design concept of carbody is to be new design to coincide with passengers emotions. In this regard, we tried to meet this trends through manufacturing of scaled models and being

The security issue in urban transit system has been widely considered as the common matters after the fire accident at Daegu subway station. The safe urban transit system is highly demanded because of the vast number of daily passengers, and it is one of the most challenging projects. We introduced a test model for integrated security system for urban transit system and built it at a subway station to demonstrate its performance. This system consists of cameras, sensor network and central monitoring software. We described the smart camera functionality in more detail. The proposed smart camera includes the moving objects recognition module, video analytics, video encoder and server module that transmits video and audio information.

This study analyze the transfer patterns of passengers in Seoul based on transit smart card data that was observed in 2010. The smart card records maximum four times of transfer and reports that approximately 90% of trips were less than one transfer and the remains were more than 2 transfers. We focus on trips with more than 3 transfers to figure out the relationship between transit service and regional connectivities. The results show that the average travel time, distance, fare are 45 minutes, 18.3km, and 1,119(KW) respectively. We develope a map for investigating transfer patterns at a regional level(dong and gu). By doing this, three types of transfers are observed as: 1) trips of which origin and destination is either same or near, 2) trips with short distance, and 3) long distance trip with low transit connectivities.

With designing alignment of railway for urban rail transit, a greater attention is paid to the riding safety and the comfort of the passengers. Especially, cant transition curve, minimum curve radius are considered as very important alignment factors for the curve. For the above alignment factors, in this study, comparative studies on the design criteria of foreign rail transit are conducted. And reasonable design criteria of the alignment for urban rail transit are proposed.

Reduction of noise level in the cabin of urban transit unit is an important issue to enhance the comfortability of passengers. It is made clear that a cause of increased noise level in cabin is the imperfect airtightness of entrance doors. In this study, the sliding-plug door system is developed to reduce the noise level of cabins by securing the airtightness of entrance door. The sliding-plug door system is composed of air-driven engine, swing arms, guide rails, guide rollers and locking devices. It is economical owing to using the previous door engine system. It is also adequate for the platform system of our subway station. It was tested to prove the reliability of system and was applied to standard urban transit unit. The effectiveness of noise reduction in cabin resulting form the sliding-plug door system was confirmed by test results.

The importance of data is increasing at a high rate as data is massively generated and taken into account in various policy supports and contents. However, because of their speed of growth, it is difficult to find the data that is needed. Both the methodological elements that summarize the data and the technical elements of the visualization that help to see at a glance are important. This paper summarizes data visualization methods to improve the currently used design - oriented infographics and propose data - centric infographics. In addition, we will present examples of data analysis and infographics production using Tableau Public. The Gwangju metropolitan city bus user data was used for infographics production, and the results show that the total number of passengers using the stopping point is similar to that of the general passengers, while it is different from the numbers of transit passengers and teen riding-and-transit passengers. Data-centric infographics visualization, unlike existing infographics that is pronounced only as a visual role, is expected to be used as a tool for scientific research as well as efficiently delivering data.

Schedule-based public transit routing algorithm computes a single route that calculated minimum travel time using the departure and arrival times for each stop according to vehicle operation plan. However, additional factors such as transfer resistance and alternative route choice are not reflected in the path finding process. Therefore, this paper proposes a improved RAPTOR that reflected transfer resistance and multi-path searching. Transfer resistance is applied at the time of transfer and different values can be set according to type of transit mode. In this study, we analyzed the algorithm's before and after results compared with actual route of passengers. It is confirmed that the proposed algorithm reflects the various route selection criteria of passengers.
