The purpose of this research is to identify new service opportunities for enhancing driving safety of intra-city buses based on driving behavior analysis. Service opportunity identification involves finding target customers of service (to whom), motivations for service (why), service contents (what), and service delivery process (when, where). This paper presents an analysis of driving behaviors using the operational data of intra-city buses in conjunction with traffic accident data and drivers' driving history data. This paper also presents four identified service opportunities based on the data analysis results. This research would contribute to enhancing driving safety of intra-city buses in Korea and serve as a basis for developing new services for driving safety enhancement.

본 연구는 운전자의 조심성에 초점을 두고 고령운전자와 청소년운전자의 운전확신수준과 운전행동과의 관계를 알아보았다. 우선, 운전확신수준을 측정하기 위한 도구를 제작하여 사용하였으며, 조사대상자들의 운전경력, 주행거리, 위반경험, 사고경험을 함께 조사하였다. 조사대상자는 만 25세 이하 청소년운전자와 만 65세 이상 고령운전자 325명이었으며, 고령운전자의 자료는 1:1 인터뷰를 통하여 수집하였다. 먼저, 운전확신수준의 구조를 알아보고자 요인분석을 실시하고, 고령운전자와 청소년운전자의 운전확신수준을 비교하였다. 그리고 고령운전자와 청소년운전자의 운전확신수준과 운전행동과의 관계를 알아보았다. 운전확신수준은 '운전상황', '안전운전', '운전능력', '주의'의 네 요인으로 이루어져 있었으며, 고령운전자의 운전확신수준은 청소년운전자의 운전확신수준보다 낮은 것으로 나타났다. 고령운전자 집단에서는 운전확신수준과 운전경력, 위반경험이 강한 상관관계를 가지고 있었고, 청소년운전자의 운전확신수준은 운전경력, 주행거리, 위반경험, 사고경험과 강한 상관관계를 가지고 있는 것으로 나타났다.

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.

본 연구에서는 Solomon이 제안한 속도편차 (주행속도와 평균속도와의 차) 개념을 이용하여 주행위험도를 정립하고, 순서프로빗모형을 이용하여 주행속도선택 기반 주행위험도평가모델을 개발한다. 제안모델을 고속도로의 차내 교통안전정보 제공효과 평가실험에 적용하여, 주행위험에 미치는 다양한 요인의 효과를 분석한 결과, 다음과 같은 연구결과가 도출되었다. 첫째, 남성이 여성보다, 경력 운전자가 초보 운전자보다, 교통사고의 경험이 적은 운전자가 고속도로를 안전하게 주행할 확률이 높다. 둘째, 고속도로를 오후에 주행하는 경우, 도로표면이 젖어있는 경우, 교통량이 한산하여 서비스수준이 너무 좋은 경우 주행위험도는 증가한다. 셋째, 경사진 회전구간을 주행하는 경우와 도로연장이 긴 곡선부 구간을 주행하는 경우 주행위험도는 증가한다. 한편, 주행위험도 증가는 차내 교통안전정보를 제공함으로써 어느 정도 감소될 수 있는 것으로 나타나 차내 교통안전정보의 제공의 중요성이 확인되었다. 본 제안 모델은 새로 도입된 교통안전시설물의 교통안전도 효과를 평가 시 교통사고 자료가 부족하거나 없는 경우 교통안전도를 평가하는데 활용할 수 있다.

This study aims to investigate dynamic properties of express buses in the very low frequencies which affect motion sickness incidence. Since passengers often use express buses for long distance traveling, it is a critical point whether a give rise to motion sickness or not. In the study accelerations at the three points on the floor of the six test vehicles were measured during the driving at constant speeds. By applying frequency weighting curves suggested in ISO 2631-1 and ISO 2631-3, physical amount of accelerations were changed into perceptual amount which determines incidence of motion sickness. Motion sickness dose values were calculated from the frequency weighted time history of accelerations, and compared between the vehicles, driving conditions, and the seat positions in the bus. During the driving on public road and high ways for 50 minutes vomiting incidence ratios ranged 0.4 to 0.8%, which were equivalent to 2.4 to 4.8% for 5 hours' driving. The value of 4.8 % means two among 45 passengers may vomit after the traveling, which is very serious situation. Considering the very smooth driving condition at which the data were collected, motion sickness dose values will increase in real situations

To find a healthy driving posture, in this study, survey and empirical analysis given onto measurement of car-seat angle has been performed. Among 153 male respondents, those drivers who has minimum 5 year experience and 2 hours daily driving has been selected by a multiple screening process. They were further confirmed to have no discomfort history in any body region caused by the driving task. Final 44 people verified that their actual driving posture is not significantly different (p = 0.692) from healthy one they think. And their data, accordingly, the healthy driving postures are clustered based on the same seat-cushion angle, seat-back angle and trunk-thigh angle. Consequently, three seat-angles of the 44 subjects showed a significant difference only with their height information which is the most effecting factor on driving posture among the physical characteristics. That is a first result categorized healthy driving posture classified physical, if it were departmentalized into additional study, could be able to reflected a factor of "healthy" on car seat design.

본 연구에서는 오류와 착오가 고령운전자의 운전행동에 어떠한 영향을 미치는지 알아보았다. 우선, 운전일탈행동의 구조와 문항의 신뢰도를 알아보기 위하여 456명의 운전자에게 운전일탈행동조사지(DBQ: Driver Behaviour Questionnaire)를 실시하였다. 그리고 883명의 운전자를 대상으로 운전일탈행동조사지를 실시하여 운전자들의 오류와 착오를 측정하였다. 참가자 가운데 만 25세 이하 청소년운전자와 만 65세 이상 고령운전자 325명을 대상으로 운전경력, 주행거리, 위반경험, 사고경험을 조사하였으며, 고령운전자의 자료는 1:1 인터뷰를 통하여 수집하였다. 그리고 운전일탈행동의 구조를 알아보고자 요인분석을 실시하고, 연령에 따른 운전일탈행동의 변화를 살펴보았다. 또한, 고령운전자와 청소년운전자를 대상으로 운전일탈행동과 운전경험과의 관계를 알아보았다. 그 결과, 운전일탈행동은 '위반', '오류', '착오'의 세 요인으로 이루어져 있었으며, 연령이 중가할수록 운전일탈행동은 감소하는 것으로 나타났다. 고령운전자와 청소년운전자 모두 운전경력이 많을수록 운전일탈행동은 적었으며, 고령운전자는 운전일탈행동 가운데 오류점수가 높고 청소년운전자는 위반점수가 높았다. 청소년운전자의 운전일탈행동은 주행거리, 위반경험과 상관관계가 있었고, 고령운전자의 운전일탈경험은 주행거리와 사고경험에 영향을 주고 있었으며, 특히 위반, 오류, 착오점수가 높을수록 고령운전자의 사고경험은 많았다.

Purpose : Recently, many researchers and golf coachers demonstrated that X-factor and X-factor stretch had a co-relationship with driving distance. However, its relationship is still controversial and ambiguous. Thus, the aim of this study was to examine the relationship among X-factor, X-factor stretch and swing-related factors, including driving distance in elite golfers. Method : Seventeen male elite golfers (handicap: ${\leq}4$) with no history of musculo-skeletal injuries participated in the study. Thirty spherical retro-reflective markers were placed on including the middle point of PSIS, the right/left ASIS, the right/left lateral acromion of the scapula, driver head and shaft grip. All motion capture data was collected at 100Hz using 6 infrared cameras. Carry distance, club speed, ball speed, smash factor, launch angle, and spin rate were collected from radar-based device, TrackMan. Results : Pearson's correlation coefficient method was used to find the correlations among X-factor, X-factor stretch and swing-related factors. Positive correlations between driving distance and other swing-related factors which include club speed(r=.798, p<.001), and ball speed(r=.948, p<.001) were observed. In contrast to the swing-related factors, X-factor and X-factor stretch had no relationship to driving distance. Conclusion : These results indicate that X-factor and X-factor stretch are not key regulators in driving distance.

Automobile was first introduced in 1903 in South Korea, the masses of the car was carried out rapidly compared to other countries. However, many people were killed in a traffic accidents and economic loss was occurred due to the spread of the automobile. In South Korea, 2012, traffic accident occurred 223,656 times, 5,392 fatality, 344,565 injured people. In the last five years, about 224,000 accidents per year were occurring. In other words, 610 traffic accidents occur and about 15 people pass away in one day. In addition, the proportion of traffic accidents is first place in the OECD countries and it is very high in the world. Understand occurrence tendency of traffic accident, accident frequency rate of the driver who drives more than 10 years was higher than the novice driver. In addition, as a result of examining the cause of the traffic accident, breach of safe driving obligation appears highest case (125,391 times), and followed by signal violation, break safety distance. Therefore, the majority of traffic accidents occurred by the lack of safety awareness of the driver. In this study, prevent the loss of human life and property in traffic disaster, by establish disaster prevention measures that investigated by questionnaire survey and statistical data of the state of consciousness and driving posture in response to the driving history of the driver.
