현재 코로나19의 여파로 아웃바운드 관광이 제한되고 있는 상황이지만 모빌리티 시장의 활성화로 인하여 안전하면서 방해받지 않는 프라이빗한 국내 여행의 수요가 증가하는 추세이다. 기존의 애플리케이션은 아직 수요자와 공급자 등의 시장 체계가 확립되지 않은 상황이다. 본 논문에서는 이러한 문제점을 해결하며 코로나19로 인하여 힘든 시간을 보내고 있는 사람들에게 힘이 되어줄 수 있는 택시 투어 통합 애플리케이션인 'TAXIO'를 개발하였다. 중장년층도 편리하게 이용 가능한 UI와 Firebase와 Google Places API, Google Maps API, Weather API를 이용하여 기존 애플리케이션보다 쉬운 접근이 가능하게 개발하였다.

In this study, the trip characteristics of workers in the city are systematically analyzed. The trip behaviors and socioeconomic characteristics of workers are analyzed using Person Trip Survey Data of 1988 and 1992 in Taegu Metropolitan area. With the results of behavioral analyses, the daily travel pattern of workers is shown as one tour contained two trips and it is relatively simple and stable. Also the rate using the same mode in a day is Presented as high ratio. So, it can be explained that the choice of worker\`s first trip is fixed his/her travel mode for his/her daily travel mode. Based on these analyses, the mode choice model for workers is developed by applying the Multi-nominal Logit Model with the choice set of bus, taxi, and car. The explanatory variables of this model include sex, age, auto, travel time, and cost. Empirical tests of the model show encouraging results. After that, the temporal transferability of the model is examined by the Pairwise t-test and five indexes far the model of 1988 and 1992. The results of examination are satisfied with each significance level of the explanatory variables and five indexes. Therefore. it can be concluded that the temporal transferability of this model developed in this study is resonable.

Recently, due to the increment of national income and the living standard of citizens, the leasure business has been dramatically expanded. Among the business, inland water activities such as cruise tour or water taxi have drawn attention from the people. As more people come for a new pleasure, the frequency and the number of services continues to rise yet the safety of people values less recently. In fact, the number of relating accidents also has risen accordingly. In order to prevent such accidents in inland waters, the vessels' real time voyage data, the advanced warning system and the emergency rescuing system are required. In this paper, we have developed navigation guiding application for safety of passengers and vessels in inland waters. Navigation guiding applications not only provide Inland Electronic Navigational Chart(IENC) and vessel information but also allows communication between traffic service center and nearby vessels in case of an emergency situation. In order to implement Navigation guiding applications, developing Inland Electronic Navigational Chart was inevitable. Therefore, IENC of Han River, has developed based on measuring the water depth using multi-beam echo sounder system.
