This paper addresses prospect of the technology for development of NxTIS (NeXt generation Transport Information System) that is targeted to shifting Korean public transit framework to railway-centered one. The Seoul metropolitan area has adopted the smart-card as a payment system for the public transportation since 2004. The transportation record can be used as quite useful information for better planning and operating of the railway system, particularly when the smart-card based payment system is extended to whole nation. This paper introduces technologies to develop Real OD DB and NxTIS, and presents road-map for them. A variety of benefits from the development of the system are estimated both in quantitative and qualitative. The Real OD DB based NxTIS will work to highly prospective for creating a novel value in the railway as a public transportation system.

The COVID-19 pandemic has brought about many changes in our daily lives and in industries as a whole. The most notable change was the spread of the untact culture to minimize face-to-face contact. The spread of the untact culture has changed the use of public transportation. Looking at the results of previous SARS and MERS studies, it was found that as the pandemic spreads, the use of public transportation decreased. Recently, the mobility sharing service is attracting attention as a personalized means of transportation instead of public transportation. Therefore, in this study, the factors affecting the intention to use the mobility sharing service were to be identified by the actual users. In this study, economic benefit, convenience, sustainability, and sense of belonging were set as independent variables based on previous studies. In addition, the relationship between the perceived usefulness and perceived pleasure of these factors of use on intention to use was empirically analyzed through PLS-SEM. As a result of the study, it was found that economic benefits, convenience, sustainability, and sense of belongingness had a significant effect on intention to use through perceived usefulness and enjoyment. This study was meaningful in that it was verified through the study that economic benefits, convenience, sustainability, and a sense of belongingness were significant variables affecting the intention to use through usefulness and pleasure.

ITS(Intelligent Transportation System) is in order to better operate the public transportation. The thesis purpose to introduce how does city buses and underground vehicles input in server-side controls to connecting these two parts, that achieve share information between them. Ready provision of reliable, up-to-date and accurate transport information contributes towards efficient road use, better traffic flow, greater road safety and improved accessibility and promote efficiency in the city.

The purpose of this paper is to provide a convenient platform for bus users and a platform to provide tourist services suitable for bus tourism as integrated services. Recently, the number of FIT tourists for recreational purposes using public transportation is increasing as the bus use environment is improved. Accordingly, we need a tourist platform that meets the needs of tourists. In particular, a bus information providing algorithm is implemented using a bus information public API to more conveniently use the bus information providing system, and a user use behavior data collection module and a data mining module To develop a contents platform based on a bus stop for bus tourism services to FIT tourists using public transportation.

The existing transportation system, which is based on internal combustion engines, is rapidly being converted to electrification. Thus, eco-friendly public transportation with high transportation efficiency will continue to spread throughout the market in the near future. The purpose of this study is to compare and analyze the cognitive characteristics of passengers redgarding the technical and social factors of various public transportation means to help a successful introduction of eco-friendly public transit. Through a survey questionnaire (N=485), seven factors of seven transportation modes were evaluated and analyzed using principal component analysis. As a result, it is confirmed that potential passengers have high expectations for the eco-friendliness and city image of the eco-friendly buses. Also, it is confirmed that eco-friendly buses are superior in cleanliness and ride comfort than diesel buses. Given the study's results, this study identifies the cognitive characteristics of passengers regarding eco-friendly public transportation. We hope that these results will be used as basic information for image positioning and improved service with the use of eco-friendly transportation.

Nowadays, the bus system of a metropolitan area is improving very fast. According to the bus, commuter railways increase their competitive power. For this, trains get the mobility increasing, effective transferring system and unified information service. For the mobility increasing, commuting railway must be faster by flexible train diagram and facilities improvement. And finally, optimal commuter train, 'Liner' is needful. And for effective transferring system, it is necessary that railway station and transferring center of a city be merged. And it is needful that direct management bus by railway company and unification fare system on metropolitan region. Next, for information service system improving, the commuting railway station must be regional transportation hub at first. And it is needful that unified line map of trunk line transportation systems and regionally collective transportation system information book. Therefore, metropolitan commuting railways compete with trunk line bus and cooperate with feeder line bus, and can make optimal metropolitan public transportation systems.

The purpose of this study is to investigate the user satisfaction of kiosk contents installed at bus stops in Seoul. A total of 400 kiosks, which are touch-based traffic information systems, are installed and operated, providing contents such as bus routes, marginal area, seoul tourism, life information, angel donation, transportation cards, magnifier and boarding requests. The study results showed that the user satisfaction scores of bus routes and transportation cards were high, but it was necessary to improve other contents. The results of this study will be used as basic data to propose user experience(UX) of public service design. We will also use it as content guidelines for public information kiosks to be developed in the future.

The new information service has been demanded due to the recent mobile internet activation, and the government is promoting the activation of the private use of the public data by putting up the Government 3.0. According to government policy, many public sectors provide public data, but the railway sector is inferior to other public sector. In the case of national railway corporation, urban railway is now operated by 14 corporations such as Seoul Metro through the nation and high-speed railway is now operated by Korea Railroad Corporation and Supreme Railways. It is very difficult to standardize and integrate data due to mutual interests of national railway corporation. This paper describes a way to standardize and integrate rail passengers information collected through research project.

Severe weather conditions, such as heavy snowfall, rain, heatwave, etc., may affect travel behaviors of people and finally change traffic patterns in transportation networks. To deal with those changes and prevent any negative impacts on the transportation system, understanding those impacts of severe weather conditions on the travel patterns is one of the critical issues in the transportation fields. Hence, this study has focused on the impacts of a weather condition on travel patterns of public transportations, especially when a heavy snowfall which is one of the most critical weather conditions. First, this study has figured out the most significant weather condition affecting changes of public transport ridership using weather information, card data for public transportation, mobile phone data; and then, developed a decision-tree model to determine complex inter-relations between various factors such as socio-economic indicators, transportation-related information, etc. As a result, the trip generation of public transportations in Seoul during a heavy snowfall is mostly related to average access times to subway stations by walk and the number of available parking lots and spaces. Meanwhile, the trip attraction is more related to business and employment densities in that destination.
