신속하고 정확한 대중교통수단의 하나로써 도심의 교통난을 해결할 수 있는 유일한 대안으로 부각되고 있는 철도차량은 여러 가지 편리함에도 불구하고 차량 주행 시 발생한 소음ㆍ진동이 철로 변 주민들에게는 하나의 환경문제를 야기시키며, 터널 주행 시에는 차량에 탑승한 승객들의 안락성을 해칠 수 있는 요소로써 그 중요성이 대두되고 있는 실정이다.(중략)

In this paper, when wheelchair user get into the vehicle, we have thorough grasp of the problems of loading wheelchair and give effect to suggest conceptual design in relation to develop manufactured goods. We choose 50 participants with disabilities who manual wheelchair or motor scooter users are able to drive own's vehicle, and the method practice in the direct survey. There are some limitations in this study especially in terms of the sampling population. The 88%(n=44) of the participant replied to the driver with disabilities need assistive devices for loading manual wheelchair. They prefer a system that robot arm brings the wheelchair out of the trunk to the driver's seat door.

In the paper, a smartphone-controlled personal mobility system(PMS) based on a compass sensor is developed. The use of a magnetic compass sensor makes the PMS move according to the heading direction of a smartphone controlled by a rider. The proposed smartphone-controlled PMS allows more intuitive interface than PMS controlled by pushing a button. As well, the magnetic compass sensor makes a role in compensating for the mechanical characteristics of motors mounted on the PMS. For adequate control of the robot, two methods: absolute and relative direction methods based on the magnetic compass sensor and wireless communication are presented. Experimental results show that the PMS is conveniently and effectively controlled by the proposed two methods.

This paper presents the driving and bouncing control of a robotic vehicle for entertainment and transportation. The robotic vehicle is aimed to carry two passengers with a balancing mechanism by two wheels. To maximize the entertaining purpose, not only the balancing control performance but the bouncing control performance is implemented. Passengers can select different driving modes such as regular driving mode, balancing mode, and bouncing mode. Experimental studies of the balancing control performance as well as the bouncing control performance are conducted to see the feasibility as an entertainment robotic vehicle.

For handicapped person who have a handicap in moving, vehicles are indispensible, especially in the viewpoint of handicapped person's participation for social life by rehabilitation, the freedom of movement equaling to nonnal person is a important factor for improving the quality in being complete growth.In the purposese of positively social participation of handicapped person, this study investigated the general problems about using a means of transportation in the users of wheelchair and for solving these problems and approached, in the viewpoint of styling, vehicles were considered from character of self-supporting in getting on and off a car. For that first, this study was progressed by suggesting invigorating convenience facilities in already established vehicles for the user of a wheelchair and the part of moulding of modified vehicles in a structure. Moreover, making a selection of domestic vehicles arbitrarily, analyzing a internal structure of a boarding of a wheelchair, and suggesting the modified model of vehicles by the sketch.

통계상 국민 2명중 1명이 차를 소유하고 있는 오늘 날, 뉴스를 통해서 차량사고에 의한 인명사고 소식을 심심치 않게 접할 수 있다. 그 중 많은 비중을 차지하고 있는 사고는 승 하차시의 접촉 사고로, 최근 들어 증가하는 추세이다. 그래서 이러한 자동차 접촉사고에서의 자동차 탑승자의 안전을 지키기 위한 대책이 시급하다고 생각하였고, 이에 본 논문에서는 뒤의 다가오는 물체에 대한 속도측정을 통한 자동 차문 잠김을 대안으로 제시하며, 이를 통해서, 자동차 탑승자들의 안전을 보장하는 것에 보다 더 한걸음 나아가고자 한다.

2,097 deaths out of 5,229 by traffic accident occurred by vehicle to vehicle crash and 855 deaths out of 2,097 occurred at side crash in 2011. Korean government adopted New Car Assessment Program to reduce the wounded and deaths at traffic accident in 1999 and side impact test has been added in 2003. 43 out of 53 vehicles tested in NCAP side impact rated 4 and 5 stars means the highest occupant protection. In this study three small class vehicles have been tested according to Insurance Institute for Highway Safety's side crashworthiness test protocol. IIHS test protocol uses 1,500kg moving barrier rather than NCAP's 950kg and the occupant protection rated Good, Acceptable, Marginal and Poor based on injury measure, structural integrity and head protection.

Survivability of combat system is changed by various facts in dynamic battle field. Existing survivability analysis programs for a combat system analyze statically survivability for combat system in spite of dynamic battle environment. To overcome this limitation, we propose an agent-based modeling and simulation method for dynamic survivability analysis of the combat system. To do this, we have adopted DEVS formalism, SES/MB framework and agent technology for modeling components of the combat system and crews. The proposed method has advantages of being able to analyze not only a static survivability of the combat system but also a dynamic survivability of combat system by applying responses of crews in battle field.

As public transportation use increases, studies are being conducted to consider user convenience using IoT data collected via the bus information system. A low-floor bus means a bus that is designed to be 20 cm lower than a normal bus and can be wheelchair-accessible. However, the system in which the transportation weak is provided to use the low-floor bus is less than the system provided to the general user. In order to use the low-floor bus smoothly, as in the case of the general user, the service system for the weak driver is needed. In this paper, a low - floor bus reservation system is designed to provide a service for low - rise bus users to conveniently use low - floor buses.
