Real-world accident cases were investigated to understand injury characteristics of the elderly driver. A total 10 cases of car-to-car frontal crash accidents from passenger car including SUV claimed to domestic car insurance company were reviewed. The injury characteristics of the elderly were analyzed from personal information (gender, age), medical treatment record (medical certificate, curative days), vehicle information (model, air-bag, seatbelt) and damage information. This study showed that elderly driver has higher possibility of thorax injury than non-elderly's. Moreover, Injury type and severity were more severe than non-elderly driver at similar type accident conditions. Also, elderly driver's medical treatment period needs 3 times more than non-elderly driver's.

Wheelchair users experience difficulty when using transportation. This is because wheelchair users must use transportation means together with wheelchairs. Therefore, in this paper, we developed a wheelchair storage system for passenger's car trunk. The mechanism is designed to allow a wheelchair and the device to be housed simultaneously in the narrow space of the trunk of the sedan passenger car. Additionally, this wheelchair storage system has implemented an initial load reduction mechanism that can mechanically reduce the initial load. This wheelchair storage system verified the system's operability through the production of the prototype. This system was actually installed in the trunk of the sedan passenger's car to verify the storage process. The operation and storage process of the wheelchair storage system was been perfectly verified. This wheelchair storage system will help a lot of self-driver or an assistant (female or elderly) who use wheelchairs.

A self-administrated non-malignant respiratory symptoms questionnaire was sent to 1,099 citizens who take subway running in Seoul city. Symptom prevalence rate was high: 70.6% of subjects reported 'chest tightness', 43.4%, 'dysphnea'; 76.2%, 'dry cough'; 49.5%, 'runny nose'; 94.4%, 'drowsiness' when they take subway. The groups responding significant higher respiratory and drowsiness symptoms were 'young passengers' (vs elderly passengers), 'the female' (vs male), 'using subway everyday' (vs often), 'using subway for rush-hour time' (vs other than rush-hour), 'using transfer subway' (no transfer), 'using underground track' (vs ground track). Logistic. regression model was employed to find personal and subway characteristics affecting non-malignant respiratory symptoms. This study concluded that respiratory diseases history such as asthma, rhinitis, sinusitis, hypersensitivity pneumonitis significantly affect 'dry cough' and 'runny nose'. Thus, passengers with respiratory diseases history shows 2.8 times greater 'dry cough' than and 3.4 times greater 'runny nose' than those passengers without respiratory diseases history felt. This results indicated that several measures have to take to protect sensitive groups such as passengers with respiratory diseases, children and elderly people. Also passenger who use to transfer shows 1.7 times higher runny nose symptoms than that passenger who do not transfer felt.

Objective: The objective of this study is to identify essential requirements of the instrument cluster's features and layout for elderly drivers through interview and paper prototyping. Background: Recent updates implemented in passenger vehicles require more complex information to be processed by drivers. Concurrently, a large portion of the US population, the baby boomer generation has aged, causing their physical and cognitive abilities to deter. Thus it is crucial that new methods be implemented into vehicle design in order to accommodate for the deterioration of mental and physical abilities. Method: Forty elderly drivers and twenty young drivers participated in this study. The test included three sessions including: 1) location value assessment to identify the priority of areas within the instrument cluster; 2) component value assessment to capture rankings of the degree of importance and frequency of use for possible instrument cluster components; and 3) paper prototyping to collect self-designed cluster with selection of designs for each component and location of features from each participant. Results: Results revealed differences in the area priority of the instrument cluster as well as the shape and location of component features for age and gender groups. Conclusion: The study provided insights on instrument cluster layout guidelines by proving elderly driver's mental model and preferred cluster design configurations to improve driving safety. Application: LCD-based vehicle instrument cluster design, with an adaptable feature configuration for cluster components and layouts.

오늘날 현대적 국가는 UN 장애인의 권리에 관한 협약을 비준하여 장애인이 차별받지 않는 환경을 조성하고 있다. 세계해사기구에서 1996년에 노인 및 장애인의 요구에 부응하기 위한 여객선의 설계 및 운영에 관한 권고안을 제시하였다. 우리나라에서는 교통약자의 이동편의 증진법이 시행되어 선박, 차량, 항공기, 철도 및 여객시설에 장애인편의시설이 신속하게 설치되고 있다. 하지만 해상교통환경은 안전에 관한 관심에 비하여 장애인에 대한 배려가 부족한 편이다. 본 연구에서는 현장 조사와 문헌조사를 통해 우리나라에서 장애인에 대한 해상교통환경을 개선하는 기초적 연구를 실시하였다. 연구결과 연안여객운송의 상당부분을 담당하는 유선과 도선 및 소규모 항구는 관련 법규의 적용이 제외되어 있었다. 또한 선박과 터미널에 장애인 교통편의시설의 설치율이 낮을 뿐만 아니라 낙후된 장비를 고려하고 있었다. 따라서 법령의 보완과 향상된 장애인 교통편의 시설을 신속하게 구축하여 인류보편적 가치인 장애인에 대한 인권을 보호해야 한다.

Purpose: Caring for weak person in society, which increases the population of the elderly and people with disabilities is essential. By increasing along with the increase of the use of passenger facilities for travelers and pedestrian is increasing the demand for convenient and secure facilities for everyone. The emerging importance of the passenger-related facilities, but a representative study of the bus terminal facilities is lacking. Bus terminals are the most popular passenger facility. Thus, the bus terminal can be conveniently used by anyone in everyday life, however, the applied elements considering the use of the transportation Poor are not sufficient. Methods: This study was conducted to evaluate BF certification standards targeting bus terminals across the country to determine the availability of the transportation Poor in bus terminal. Result: As a result of the bus Terminal possibility BF certified it appeared to be very low. Also, items received the lowest rating of each item was evaluated in the informative facilities and items. Bus terminal is a facility used by the unspecified individuals, the proportion of first-time user is high, but there is a lack of consideration for the transportation Poor bus terminals. Implications: In the future, this study can guide the next research on the application of BF certification standards in bus terminal. Further studies can be presented to the improvement of the BF certification indicator in bus terminal.

버스는 대중적으로 많이 이용되는 교통수단이다. 그만큼 승객의 안전관리를 위해 철저한 대비가 필요하다. 하지만 2018년 승차하기 위해 접근하는 노인을 인지하지 못하고 버스가 출발하면서 사망사고가 발생하는 등 안전 시스템이 미흡한 상황이다. 기존에 뒷문 계단 쪽 센서를 통해 끼임 사고를 방지하는 안전 시스템은 있지만, 이러한 시스템은 위 사고처럼 승하차하려는 과정에서 발생하는 사고를 예방하진 못한다. 버스 승객의 승하차 의도를 예측할 수 있다면, 위와 같은 사고를 예방하는 안전 시스템 개발에 도움이 될 것이다. 그러나 승객의 승하차 의도를 예측하는 연구는 부족한 상태이다. 따라서 본 논문에서는 버스에 부착된 카메라 영상에서 UDP-Pose를 통해 승객의 skeleton keypoints를 추출하고, 이를 활용한 1×1 CNN3D 기반의 버스 승객 승하차 의도를 예측하는 모델을 제안한다. 제안한 모델은 승객의 승하차 의도를 예측하는 부분에서 RNN, LSTM 모델보다 약 1~2% 높은 정확도를 보여준다.

고령화가 급격한 속도로 진행되며 발생하는 문제 중 고령 운전자 사고는 해결되어야 하는 중요한 사회문제이며 사고를 감소하고자 하는 노력은 앞으로 맞이할 초고령 사회를 대비하기 위해 꼭 필요하다. 현재 고령자는 65세 이상으로 규정되어 있으며 이에 따라 고령 운전자 사고에 관련된 다양한 연구들은 65세를 기준으로 일반운전자와 고령 운전자를 구분하여 분석한다. 이러한 배경으로 인해 수용 가능한 정확도의 수준에서 실질적으로 교통약자로 분류되어야 하는 신체 능력을 갖춘 고령 운전자를 구분하는 기준은 제시되고 있지 않다. 따라서 본 연구에서는 상관분석을 이용하여 고령 운전자의 연령별 사고특성을 분석하여 연령군집별 사고 위험성을 비교하도록 한다. 분석결과 차종별 주요 사고특성에 대해 75세 이상의 경우 사고 발생에 미치는 영향력이 높아지는 것으로 나타났으며, 70세에서 80세 사이 구간에서 사고 발생 빈도가 상대적으로 낮았던 승용차에 대해서도 주요사고특성을 분석한 결과 75세 이상 84세 이하 구간에서 사고 발생에 대한 영향력이 높아지는 것이 두드러지게 나타났다. 이는 고령화가 진행되고 평균 수명이 늘어남으로써 고령자 구간 폭도 증가하는바, 고령자 내에서도 특성이 나뉘게 되며 본 연구를 통해 연령군집별로 사고 발생에 대한 영향력이 달라지는 것을 확인하였다.

The Fuel cell Rubber tired Train (FRT), which is now getting the attention as the next generation vehicle with its environment-friendliness, is the transportation for smooth connections of city traffic. It is the revival of the surface-car system with its revaluation of the function and technological development. Accordingly, fixed time operation and high speed driving became possible. FRT is operated together with other vehicles on the regular drive way. While this vehicle can solve the problem of traffic congestion in the urban area, it also can be cost-effective when it is compared to the cost of subway construction. It is also designed to minimize the underground or elevated traffic lane, to introduce the new construction technology, to reduce a term of works, and to cut down the operation cost by unmanned automatic driving system. Furthermore, it is considered as the alternative measure of other transportation due to its potential for the ecological way of speed improvement and the accessability to the disabled, elderly and children by developing the vehicle with folding steps or by building the high boarding platforms. In this research, I concentrated on the user oriented interior design of the FRT to make it passenger-friendly and safe in order to maximize the utilization of the vehicle so that all users including wheelchaired, user with baby carriage, elderly and children can conveniently use this vehicle.
