Since 1971, the aptitude test for domestic train drivers has been long maintained. With the revision of the Railroad Safety Act in 2006, the aptitude test was changed from the type of written and skill test into the type of question-and-answer and reaction test. However, the main structure of the test was not changed. In this paper, we focus our attention on the improvement of the present aptitude test. We surveyed on two groups, one is the railroad expert group and another is train driver's group, questioning about the importance of the domestic and foreign aptitude test items. Based on the analysis, we suggest desirable aptitude test system for the railroad safety.

To verify the effect of driver's personal characteristics of driver on the accident frequency through railway accidents caused by human errors and the relationship with aptitude test. To prove the relevance between the driver's personal characteristics and human error accidents. Accident data from 2010 to 2011 was analyzed which collected from a train crew department in K national corporation, and 31 drivers gave an personal interview from Sep. 2011 to Nov. 2011 who had controlled a train alone and caused an accident. Compared between driver's personal characteristics and accident rate, and accident induction possibility surveyed from normal person and disqualified in aptitude tests. Accidents was occurred with the age 40s (27%) and 50s (25%), and with the experience between 15 years and 20 years (38%) and over 20 years (30%). Because more aged, more experienced, it can be seen in the correlation between driver's age and accidents induction caused by human errors like illusion. First of all it must be checked whether working conditions and environmental factors are human error-prone. Most accidents occur when received civil complaints or manager at the riding. Therefore accidents can be prevented when investigated through subsequent surveys how often human error happens, even though no accident, and safety device installed based on the error frequency.

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.

This paper reports the aging driver traffic accident severity modeling results. For the modeling, Poisson regression approach is applied using the data set obtained from the Korea Transportation Safety Authority's simulator-based driver aptitude test results. The test items include the estimations of moving objects' speed and stopping distance, drivers' multi-task capability, and kinetic depth perception and so on. The resulting model with the response variable of equivalent property damage only(EPDO) indicated that EPDO is significantly influenced by moving objects' speed estimation and drivers' multi-task capabilities. More interestingly, a comparison with the younger driver model revealed that the degradation of such capabilities may result in severer crashes for older drivers as suggested by the higher estimated parameters for the older driver model.

본 연구에서는 운수종사자시스템과 운행기록분석시스템을 활용하여 시내버스 고령운전자 운전적성정밀검사의 신규검사결과, 사고 및 벌점현황, 운행기록자료를 분석하였다. 분석결과 시내버스 고령운전자를 사고수가 많은 관심대상 운수회사와 관리가 잘 되고 있는 교통안전 우수회사와 비교했을 경우 운전적성정밀검사의 결과는 비슷하였으나 최근 5년 동안 운행하면서 발생한 총 벌점은 상당한 차이를 보였고 사고의 경우 평균 중상자수와 경상자의 수도 적은 것으로 확인됐다. 또한 운행 100km당 위험운전행동 횟수를 비교해보면 우수회사의 고령운전자는 다른 고령운전자와 비고령운전자와 비교해서도 위험운전행동 횟수가 상당히 적은데 잘못된 운전습관의 교정결과에 따른 것으로 나타났다.

The weight of elderly people in Korea has been increasing. Statistics show that the percentage of the elderly people in Korea was 3.1% in 1970; 3.8% in 1980; 5.1% in 1990, and 7.2% in 2000. Based on this trend, thus, the number of elderly people could be estimated to be 14% of the whole Korean population in 2018. This reveals that Korea is entering a super-aging society with remarkable fast pace. In such a change, the statistics related to elderly people driving license and the occurrence of traffic accidents are showing a noticeable numerical value. The number of traffic accident fatality in Korea ranks the highest value in OECD Countries. However, the research on old drivers in the nation is going on partially centering on system improvement and management scheme. Thus, first of all, researches about the linkage & characteristics between the driving behavior of old drivers and traffic accident should be implemented, in order properly to draw system improvement and management scheme for the old drivers. Therefore, the focus of this study is the influence model for discerning the severity of the age-old-caused traffic accidents by inquiring into the relation between the Driving Aptitude Test items that make it possible to measure their behavioral characteristics and influential factors by age group on the basis of the data on traffic accidents. The analysis results can be used as basic data for suggesting the behavioral research and countermeasure for traffic safety and its management for old driver in preparation for the aging society.

A traffic fatality by young people marked average annual decrease of 4.5% since 2011. Meanwhile, a traffic fatality by senior over 65 years old marked average annual increase of 7.9% for the last five years which means that the annual increase of traffic fatality by senior will be a serious problem. This study started questioning that senior drivers over 65 years old did not retain the same causal factor of fatal traffic accidents and thus extensively analyzed a risk of it by age group quantitatively, dividing the senior driver group into the early, middle and latter stages. Depending on the aging level, the risk of traffic fatality showed a wide difference in seven different types of traffic accidents generally, and happened to increase with latter and middle parts of the senior driver more than the early part. Therefore, this study proposes four policy suggestions: 1) The senior driver need to be offered customized driving educations and the improvement of road environment is also recommended. 2) Political assistance is needed to support and guide a safety related technology installation for the new or existing car. 3) Renewal of driving license and an aptitude test(physical examination, cognitive test) for drivers over 75 years old should take in a less than 3 years and an additional road test is needed as occasion demands. 4) Like the United States and Europe, development and extension of customized treatment guidebook for medical teams who examine senior drivers is needed and establishment of education and administration system that a supervisor of driving license renewal can impose safety restriction and American anonymity reporting system is considered to institutionalize in the medium to longer term.

본 연구는 사업용 운전자들의 상황인식 능력이 사고 유발 회수나 심각성, 벌점 등과 관련성이 있는지 알아보기 위한 목적을 가지고 진행되었다. 이를 위해 상황인식의 지각 단계와 이해 단계의 능력을 측정하기 위한 상황지각 검사와 위험판단 검사를 제작하고, 운전정밀 특별검사 대상자인 사업용 운전자 228명에게 새로 개발된 시뮬레이터 기기를 이용하여 상황지각 검사와 위험판단 검사를 시행하였다. 개발된 과제의 수행 결과는 최종 5등급으로 판정이 내려지도록 설계되었는데 가장 수행이 좋은 경우 1등급, 수행이 나쁜 경우 5등급 판정을 받도록 하였다. 연구 결과, 상황지각 검사에서의 저조한 등급은 누산벌점과 사고 다발도, 안전도 지수와 정적인 상관이 있었으며 위험판단 검사의 등급은 사고 다발도와 안전도 지수와 정적인 상관이 있었다. 이는 사업용 운전자들의 상황인식 능력이 법규위반 및 사고 유발 경향과 관련이 있음을 보여준다.

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.
