  • While there are many services that can check current traffic condition and application program such as bus arrival alarm are developed, since it only provide simple alarm and check level of information, it is still insufficient in many senses. Therefore, the program that try to develop in this study is the system that predict arrival time to destination and inform the bus passengers by applying real time traffic information. The system developed related to this study is still very inadequate. In the system developed in this thesis, when the user input the current bus number and destination using smart-phone, relevant server acquire the bus route information from bus information DB, and analyze real time traffic information based on the information from traffic information DB, and inform customer of expected arrival time to destination. In this thesis, traffic congestion can be eased off and regular operation of public transportation can be improved with reliable destination arrival alarm. Also, it is considered that pattern of bus users can be analyzed by using these information, and analyzing average transport speed and time of public transportation, travel time depending on various situation can give a boost to study related to transportation information and its development.

  • The advancement of autonomous driving technology has heightened the importance of Autonomous Mobile Robotics (AMR) within smart factories. Notably, in tasks involving the transportation of heavy objects, the consideration of weight in route optimization and path planning has become crucial. There is ongoing research on local path planning, such as Dijkstra, A*, and RRT*, focusing on minimizing travel time and distance within smart factory warehouses. Additionally, there are ongoing simultaneous studies on route optimization, including TSP algorithms for various path explorations and on minimizing energy consumption in mobile robotics operations. However, previous studies have often overlooked the weight of the objects being transported, emphasizing only minimal travel time or distance. Therefore, this research proposes route planning that accounts for the maximum payload capacity of mobile robotics and offers load-optimized path planning for multi-destination transportation. Considering the load, a genetic algorithm with the objectives of minimizing both travel time and distance, as well as energy consumption is employed. This approach is expected to enhance the efficiency of mobility within smart factories.

  • A station is the place for the passenger who load the baggage or for bus, taxi, train to stop regularly. For example, bus stop which is installed on many areas for bus as a public transportation provides some space to the passenger who waits for getting on the bus. The bus stop built up recently carries on many kinds of function to make the passenger convenient different from the conventional simple bus stop. Smart station for Bimodal Tram combined with ITS(Intelligent Transportation System) technology has the advantages of both new and conventional stations. This paper has investigated the function and role of newly developed smart station which is able to be adaptive to the rapid variation of road station.

  • Before COVID-19, tourist destinations have experienced problems with congestion of both famous tourist attractions and public transportation. Over-tourism is not an issue at this time, but it is likely to rekindle after the COVID-19 pandemic ends. One method of mitigating over-tourism is to estimate tourist behavior using a tourist transition model and consequently adjust public transportation operations. In this study, we propose a construction method for a model of tourist transitions among tourist attractions based on tourist GPS trajectory data. We construct tourist transition models using actual trajectory data for tourists staying in the vicinity of Kyoto City. The results verify the model performance.

  • Currently, the most important issue on the earth is global warming, which causes climate change and leads to disasters. For this reason, each country is focusing on renewable energy, carbon neutrality, environmentally friendly energy and transportation. Bicycles used as short-distance vehicles do not emit gases harmful to the human body that pollute the Earth's atmosphere. Also, the use of bicycles has the effect of improving the health of people, and each country is designing a short distance transportation network using bicycles. In this study, we propose a model of a bicycle power-train that can use a belt as a power transmission medium. The basic principles and methods for applying the proposed new type of power-train to bicycles are presented.

  • 교통카드 데이터는 승하차 정류장과 시각 등 활용가능성 높은 정보들을 포함하고 있어 대중교통 분야에서 다양하게 활용되고 있다. 데이터 수집·저장 과정에서 물리적·환경적 요인에 의해 다양한 오류가 교통카드 데이터에 존재하지만, 오류 유형과 보정에 대한 연구는 부족한 상황이다. 본 논문에서는 교통카드 데이터의 승하차 정류장 정보 오류를 상세히 살펴보았다. 제주특별자치도에서 수행된 버스승하차조사 자료와 동일 기간을 대상으로 수집된 교통카드 데이터와 승차정류장을 중심으로 비교한 결과 교통카드 데이터의 승차정류장 정보 오류율이 6.2% 수준으로 보정이 필요함을 확인하였다. 6단계로 구성된 버스정보시스템 데이터 기반 교통카드 승하차 정류장 정보 오류 보정 알고리즘을 제시하였다. 버스승하차조사 자료와 버스정보시스템 데이터를 비교한 결과 승차정류장 정보 일치율은 98..3% 수준으로 버스정보시스템 데이터를 활용하여 정류장 오류 보정 가능성을 확인하였다. 본 논문에서 제시한 교통카드 승하차 정류장 정보 오류 보정 알고리즘의 성능을 승차정류장을 중심으로 누락을 제외하고 평가한 결과 교통카드 승차정류장 정보 오류율이 보정 전 6.2%에서 보정 후 1.0%로 5.2%p 감소한 것으로 나타났다. 정류장 정보 오류가 보정된 교통카드 데이터를 통해 버스 노선 조정과 대중교통 인프라 투자 정책의사 결정이 보다 합리적으로 수행될 수 있을 것으로 기대된다.
