고령운전자를 대상으로 하는 운전적성검사 체계는 국내에 다수 마련되어 있으나, 실차주행을 통해 실질적인 운전능력을 평가하는 항목 및 체계는 마련되어 있지 않다. 따라서 본 연구에서는 현재 국내에 존재하는 실차주행 평가방식인 기능시험 평가항목이 고령·일반 운전자의 운전능력 차이를 설명하는지 확인하고, 장내기능시험장을 활용하여 별도 평가항목을 개발하고자 실차주행실험을 수행하였으며, 운전자별 주행행태 데이터를 비교·분석하여 연령 및 신체·인지 능력에 따른 고령운전자의 운전능력 관련 통계적 유의성을 검토하였다. 그 결과, 기존의 기능시험 평가항목보다 별도 개발한 평가항목이 운전능력에 대해 더 높은 설명력을 갖추고 있음을 확인하였다. 이 결과를 바탕으로, 실차주행을 통한 실질적인 고령운전자 운전능력 평가방법 마련 및 시스템 개발에 대한 방향성 및 시사점을 제시하였다.

연구목적 : 본 연구의 목적은 뇌졸중 환자에게 운전 시뮬레이터와 Dynavision 훈련의 효과를 인지 평가와 주행 중 운전수행 능력 평가를 통해 비교하고, 두 가지 훈련방법의 차이에 대한 임상적 근거를 제시하는 것이다. 연구방법 : 본 연구를 위해 뇌졸중 환자 21명을 선정하여 무작위로 운전 시뮬레이터 훈련 집단(N=11)과 Dynavision 훈련 집단(N=10)으로 분류하고 각각 15회기의 훈련을 실시하였다. 대상자들의 주행 중 운전수행 능력 측정을 위해 운전 시뮬레이터 시나리오 시스템 평가를 실시하였고, 인지 능력을 측정하기 위해 DriveABLE Cognitive Assessment Tool(DCAT), Trail Making Test-A, Trail Making Test-B 그리고 Mini Mental State Examination-K 평가를 실시하였다. 결과 : 운전 시뮬레이터 훈련 집단은 모든 인지 능력평가와 대부분 운전수행 능력에서 통계적으로 유의미한 향상이 확인되었다. Dynavision 훈련 집단은 Trail Making Test-A를 제외한 모든 인지 능력 평가와 브레이크 페달 반응시간, 중앙선 침범 평균 시간 및 비율, 차선이탈 비율의 운전수행 능력에서 통계적으로 유의미하게 향상 되었다. 그리고 두 가지 훈련의 변화량은 도로주행평가의 결과 예측 지수와, 충돌사고 및 위험상황 발생 횟수에서 유의미한 차이를 보였으며, 이 변수들의 변화량은 두 가지 훈련방법의 적용 차이에 따라 모든 변수가 20% 이상의 인과적 영향력이 있음이 확인되었다. 결론 : 뇌졸중 환자의 운전훈련 방법으로 운전 시뮬레이터와 Dynavision 훈련은 모두 효과적인 중재방법임을 확인하였다. 특히 운전 시뮬레이터는 뇌졸중 환자의 운전수행 능력 전반을 향상시킬 수 있는 효과적인 훈련이며, Dynavision 훈련과는 20%의 설명력으로 훈련효과의 차이가 확인되었다.

This study deals with characteristics and risk of a PM based on user survey result, road driving test and data analysis of PM accident. Text mining method is applied to extract PM accident data from Big Data, which are claim data of private insurance company. Road driving test and survey on safety, convenience, noise, overtake ability, steering ability, and climbing ability of PM are performed to evaluate user's safety and convenience considering domestic road condition. As the result of claim data analysis, annual average increase rate of PM accident is 47.4% and average compensation of personal mobility is higher than that of bicycle by maximum 1.5 times. 79.8% of PM accident is self-caused accident due to unskilled driving and age-specific diagnosis rate of driver over 60 is higher than that of under 60. Diagnosis rate of over 60 at lower limb, foot, rib and spine is especially higher than that of under 60. As the result of road driving test and user survey, satisfaction level on safety and convenience of PM is evaluated as close to that of bicycle and satisfaction level of PM is increased after boarding. Overtake ability, steering ability, and climbing ability of PM are evaluated as same or better than that of bicycle but warning equipment to pedestrian or bike such as horn is required because noise level of PM during driving is too low. Finally, user survey result shows that bicycle road is suitable for PM and safety standard, advance-education and insurance are required for PM. It is suggested that drivers' license for PM can be replaced by advance-education. Results of this study can be used to prepare safety measures and legal basis for PM operation.

Purpose : This study examined the effects of driving rehabilitation functional training on visual perception ability and driving reaction velocity. Those subjects were put under MVPT-3 test to see their visual perceptual functions before and after the 4weeks' driving rehabilitation function training and then put to TMT A-type test to see their driving reaction velocity performance. The followings are the results of this study. Methods : Using a driving simulator, driving rehabilitation functional training was performed targeting men and women aged in 20s 20 minutes per time, two times per week, for a month. Results : As for the change in visual perception, the Raw Score of MVPT-3 very significantly increased (p<.01), and the Standard Score also very significantly increased (p<.01). As for the change in reaction velocity, TMT A-type very significantly decreased (p<.01), and TMT B-type also very significantly decreased (p<.01). Conclusion : It could be found that driving rehabilitation functional training should be effective for both visual perception and reaction velocity. Consequently, the driving rehabilitation function training can be applied to clinics as training method for functional recovery and improvement of visual perceptual functions and driving reaction velocity performance ability of the patients. Thus, various functional programs should be studied in the future.

Objective: The left and right sides of the brain has different roles. This study investigated the differences in cognitive driving ability between stroke survivors with damage to the left brain and right brain. Therefore, the purpose of this study was to compare the driving cognitive ability of left and right hemispheric drivers following stroke. Design: Cross-sectional study. Methods: The Stroke Drivers' Screening Assessment (SDSA) from the UK was translated to the Korean Stroke Drivers' Screening Assessment (K-SDSA) to meet the specific traffic environments of Korea. The SDSA is composed of 4 tasks :1) a dot cancellation task that measures concentration and visuospatial abilities necessary for driving, 2) a directional matrix task to measure spatio-temporal executive function required for driving, 3) a compass matrix task to measure accurate direction determination ability required for driving, and 4) recognition of traffic signs and reasoning ability to understanding traffic situation. The SDSA assessment time is about 30 minutes. The K-SDSA was used to compare the cognitive driving abilities between 15 stroke survivors with left and 15 stroke survivors with right brain damage. Results: There were significant differences between the persons with stroke patients with left brain lesions (right hemiplegia) compared to the persons with stroke with right brain lesions (left hemiplegia) (p<0.05). It was found that the cognitive driving ability of those with right brain damage was lower than that of the group of left brain damage. Conclusions: This research investigated the driving cognitive ability of persons with stroke. The therapists can use this information as basis for the driving test and training purposes. It could also be used as a basis to understanding if the cognitive ability of not only stroke survivors but also those with brain damage is adequate to actually drive.

This study aims to identity the age group where driving performance significantly decreases based on the data collected from the Korea Transportation Safety Authority's driver aptitude tests in 2006. The test includes following six driving simulator-based tests: estimation of moving objects' speed, estimation of stopping distance, three tests for drivers' multi-task ability, and kinetic depth perception. These six test results were utilized for the identification of the age threshold applying the CART technique, suggesting driving ability significantly be decreased over 50s. This finding was confirmed by two analyses using the accident history data containing the information of accident and non-accident drivers and the degree of accident severity. The results of this study imply that accident prevention efforts should be enhanced over a wider range of age group than the current practice where the age of 65 is generally applied for the threshold dividing senior and non-senior driver groups.

Brain injured patients who had the driver's license before the injury of the brain were tested with the newly developed tool CPAD by Hangyang Medical School and the National Rehabilitation Center. The CPAD contains many variables to measure the ability of driving. Also for each patient the American standard CBDI score was measured and the result was compared with the CPAD results. Of interest is to classify the patients as pass, border, fail group after the CPAD test. To derive the discriminant functions with the group information based on CBDI, parametric/nonparametric and multivariate/univariate discriminant analysis was performed and discussed.
