In this paper, we utilize a service provided by the existing bus information system. To improve the limitations of the bus information system the information provided to the passenger using the bus. By applying the IoT sensor network system. congestion information of the bus provided to customer. Provides information in addition to the existing bus congestion information to passengers wishing to use public transport from the smartphone app with an existing information system. The bus congestion information in addition to the existing information to passengers who want to use public transport provided in the existing information system and smartphone apps. Prevent accidents that might occur due to congestion in the bus, efficient and convenient way to propose an improved bus information system for public transport. Developed a prototype system using the IOT sensor network verified the proposed method.

This study intends to construct scenic byway database and to examine and suggest social experiment of scenic byway. As basis work for the experiment of the scenic byway, we build database by using ITS standard node link management system. The DB includes scenic byway routes of Korea and Japan. The analyses show that the scenic byway in both nations consists of roads, reservation, road sign, vehicle number plate, and it was found that infrastructure and system are inadequate for scenic byway. These experiment can be effectively used for scenic byway in Korea and Japan as the basis data. The results of this experiment will be useful for plan and develop a scenic byway.

It can prevent traffic accidents in a way as taking precautionary measures for road safety at signalized intersection in advance. Particularly, traffic accidents can be reduced at relatively low cost without redesigning alignments. That is 'Positive Guidance method' which can help prevent traffic accidents through improvement of road facilities at signalized intersection. In this study, potentially higher hazardous signalized intersection due to speeding was selected through site investigation. Field analysis at designated section was conducted and devised a plan for improvements of road facilities. Subjects drove in driving simulator in 3-D virtual reality of designated intersection. Based on data from simulator, statistical analysis(t-verification) was conducted for 'Before and After effectiveness' of speed reduction. As a result, it indicates that speed reduction was effective after improvements at each spot in driving simulator. In the future, hazardous signalized intersections which can be applied for PG method will be effective for road safety based on this research.

The purpose of this study is to analyse the effect of the parking information on the waiting time using the simulation method. Stated Preference survey has been implemented to construct the parking lot choice model. A queue simulation is carried out to investigate the effect of various parking information on the waiting time. The results show that providing parking information is likely to increase the utilization of parking place and to decease the waiting time of individual vehicle. Furthermore, as the parking demand increases, the detailed and quantitative parking information such as "5 minutes delay" is more effective than qualitative parking information such as "available".

When the drivers try to read an information on road signs, they can reach their destinations successfully. In this situation, human factors, road signs and geometric condition regarded as the most important factors for a safe driving should be a well-balanced relationship mutually. This research aims to prove the factors obstructing a safe driving, while drivers try to read an information on road signs for the next destination. For this sake, driving simulator was used and human factors, road signs etc. were considered in this experiment. The statistical analysis indicated what factors disturb a safe driving. The probability function using a Logistic Model was presented in this study. This result and experience will be used as a basic data in designing better road signs.

본 소고의 목적은 중국과 한국의 지하철 역사 내에 있는 시각정보디자인의 양식 및 감성의 비교연구이다. 한국의 마찬가지로 중국 사회도 급속한 경제성장과 더불어 지하공간의 중요성이 증대되어지고 있다. 그리하여 지하교통의 아내시스템의 중요성이 더욱 뚜렷하게 나타나게 되었다. 지하 공간에서 시각적 정보 디자인 성패의 가장 큰 평가기준은 바로 그 디자인에 대한 대중들의 인지도의 강약이라 할 수 있다. 그러나 지하철의 역할이 중요함에도 불구하고, 안내 시스템 등과 같은 일부 지하철 내부의 시각적 정보들은 사람들의 출입 등에 편의를 제공해주지 못하고 있다. 또한 각 지하철 역사내 시각정보시스템의 통일된 체계 구축과 함께 지역적 특성도 부가되어야만 한다. 때문에 시각적 정보에 대한 대중들의 인지도를 어떻게 높일가? 하는 문제는 모든 지하공간의 시각정보디자인에 있어서 반드시 해결해야 할 문제가 되었다. 본 논문에서는 한구 부산의 서면 지하철 역과 베이징 서지문 지하철 역 내부의 시각적 정보 디자인의 색채 조형 문자 등 시각 디자인을 구성하는 전반적인 관련요소에 대한 비교와 분석을 통해, 서로 다른 문화의 영항 하에서 두 곳의 시각적 정보 디자인의 공통점과 감성의 다른 점 및 어떤 디자인이 대중들의 시각적 정보 디자인의 인지도 높일 수 있는지에 대한 연구를 진행하고자 한다.

The objective of this paper is to propose the bus information system that provides bus passenger number. Recently, we use a bus conveniently through introduction of bus information system offering location-based information. However, we need additional information for decision making in order to use a bus comfortably. To do this, first, we analyzed the needs of providing passenger number; second, we adopted GPS and RFID type's transportation card to get location and passenger number. Finally, we implemented the system displaying that information by three types, and tested it. Our proposed system has advantages to use a bus comfortably and to manage a bus efficiently by providing bus passenger number which is the important element for decision making as well as location based information provided by existing bus information systems.

In this paper, we implemented that MMT(Multimedia Terminal) demonstrates spot news, weather forecast, sports news and cultural news employed CDMA mobile communication networks. The MMT displays mobile pictures/joint pictures/on screen ad and to make known Bus stop or Mobile stations. The MMT gives driver's and passenger's safety and valuable information for one's use GPS satellites. We verified to make real time mobile picture transfer use of CDMA2000 1×(IS-95C) network and development the scheduler control each module. This system tested on vehicle that train and bus. MMT was implemented high reliability and stability by the embedded system. The mobile terminal shows reliable data transfer rate about 74Kbps on IS-95C.

Monorail, with the cutting edge technology from EMU system, is small to medium sized transportation solution with bus size capacity, and one of key factors is to minimize size and weight. The Wolmi urban tour monorail, which is a center guide type first ever introduced in the world, is also consists minimizing size and weight of the propulsion system (inverter and motor), which generates considerable amount of heat. This study presents a solution of the structure and method of water cooling system of minimize the size and weight of high efficiency propulsion system, and an effective control method for energy saving.
