본 연구에서는 연령증가에 따라 운전에 필요한 신체적, 인지적 능력의 변화가 어떻게 나타나는지 설문을 통해 분석하고, 이것이 교통안전 시설물(신호기, 노면표시, 도로표지판)의 필요성 및 적정성을 평가하는 것과 어떤 관계가 있는 지 살펴보고자 하였다. 이를 위해 20세 이상 운전면허 소지자를 대상으로 5개 권역, 500명을 대상으로 설문조사를 실시하여 이를 분석하였다. 운전능력에 대한 자기평가 점수는 종합적 능력, 개별능력(시력, 청력, 색채식별 등) 모두 연령이 증가함에 따라 점수가 낮아지는 것으로 분석되었다. 특히 시력은 연령증가에 따른 감소폭이 크고, 절대적인 평균점수가 다른 항목에 비하여 낮게 나타났다. 시력의 경우 타 신체적, 인지적 능력에 비해 운전 중 기능의 저하에 따른 체감도가 크기 때문인 것으로 판단된다. 설문결과에 따른 분류분석을 통해서는 신체적, 인지적 기능의 저하가 시작되는 연령이 기존의 고령운전자로 판단하는 65세 보다 낮은 48세로 분석되었다. 이것은 연령증가에 따른 기능 저하로 인한 영향을 받는 운전자가 그렇지 않은 운전자보다 더 많다는 것을 의미한다. 또한 시설물에 대한 필요성 인식에 대한 평가 역시 운전능력에서 차이를 나타내는 연령대에서 인식의 차이가 있을 것으로 분석되었다.

현재 고령자는 65세 이상으로 정해져 있고 고령 운전자 사고에 관련된 연구들은 65세를 기준으로 일반 운전자와 고령 운전자를 구분한다. 하지만 실질적으로 교통약자로 분류되어야 하는 신체 능력을 가진 고령 운전자를 구분하는 연구는 부족한 실정이다. 분석결과 차종별 주요 사고특성에 대해 70세 이상의 경우 사고 발생에 미치는 영향력이 높아지는 것으로 나타났으며, 70~80세 구간에서 사고 발생 빈도가 상대적으로 낮았던 승용차에 대해서도 주요사고특성을 분석한 결과 75~84세 구간에서 사고 발생에 대한 영향력이 높아지는 것이 나타났다. 이는 고령화가 진행되고 평균 수명이 늘어나 고령자 구간 폭도 증가하기 때문에, 고령자 내에서도 특성이 나뉘게 되고 본 연구를 통해 연령군집별로 사고 발생에 대한 영향력이 달라지는 것을 확인하였다.

This study focused on the effects of median type on drivers' subjective sense of speed and the changes in this sense by driver age. Participants were 61 drivers: 20 young (aged 20-39 years), 19 middle-aged (40-59 years), and 22 older drivers (60+ years). The participants watched each of two driving scenarios, showing either a guardrail-equipped or a concrete median. The participants were asked to push a button when they perceived speeds of 60 km/h, 80 km/h, or 100 km/h. All drivers perceived higher speeds in the guardrail condition than in the concrete condition. Perceived speeds increased with driver age in both guardrail and concrete conditions. These results mean median type affects drivers' subjective sense of speed even as driver age increases, and that drivers' subjective sense of speed tends to increase with age.

This study investigated the differential interactive effects of the combination of driving confidence and sensation-seeking on driving anger among different age groups, by using correlation analysis, a hierarchical regression and ANOVAs for the data gathered through the questionnaires administrated in a form of face-to-face interview. The results showed the followings. First, males tended to show higher level in driving anger than females. Second, whereas sensation-seeking was positively correlated with driving anger, age and driving experience were negatively correlated with driving anger, respectively. Third, although there was no significant relationship between driving confidence and driving anger among the drivers aged under 40 years, the drivers aged over 40 years showed higher level of driving anger as their driving confidence increased. Forth, level of sensation-seeking was found to be a strong predictor of driving anger in all age groups. Fifth, driving confidence and sensation-seeking appeared to affect the level of driving anger interactively among drivers aged under 40 years or over 65 years, resulting in higher driving anger only when both the levels of driving confidence and sensation-seeking were high. In contrast, driving confidence and sensation-seeking affected driving anger independently among the drivers aged 30-49 years. Implication and suggestion were discussed.

This study investigated the differential effects of subjective evaluation for attention and situation adaptability, and motivation on driving mobility as a function of driver's age. The results can be summarized as followings. First, subjective capability evaluation tended to decrease as the drivers' age increased, and lower evaluation for situation adaptability seemed to be recognized earlier than attentional ability in middle-aged drivers. Second, although subjective evaluation for attentional ability predicted positively driving mobility of all age groups, but only subjective evaluation for situation adaptability predicted positively driving mobility of older drivers. Third, among motivational elements, BAS predicted positively driving mobility of young and middle-aged driviers, whereas BIS predicted positively driving mobility of older drivers. Finally, middle-aged drivers tended show increased driving mobility when their attentional ability score and BAS were high, whereas older drivers showed lowest level of driving mobility when their situation adaptability score and BIS were low. These results suggest importance of integrated consideration for drivers' subjective evaluation for attention and situation adaptability, and motivation to understand characteristics of driving mobility in different age groups.

With the rapid progress of ageing several issues concurrently occur, and one important social issue that must be resolved is accidents involving Elderly drivers. Efforts to reduce the frequency of such accidents is a must in order to be prepared to face a superaged society. Currently people aged 65 or older are prescribed as an "Elderly person." Therefore, various studies concerning accidents involving Elderly drivers apply this age criteria to separate regular drivers and Elderly drivers. However, there is no criteria to practically discern Elderly drivers with certain physical features as vulnerable road users based on a level of acceptable accuracy. Therefore, this studies intends to compare the possibility of accidents by age group of Elderly drivers by correlation analysis to analyze the accident characteristics by age group. Results showed that for drivers aged 75 and older, their influence on major accident characteristics by vehicle type increased with higher age groups. In particular, passenger cars had a relatively low accident frequency rate for drivers aged between 70 and 80, but for drivers aged 75 to 84, they had higher influence on accidents for the same vehicle type. This demonstrates that as ageing progresses and the average life expectancy increases, the age span of elders continues to increase, meaning that characteristics differ by age group among the aged. This study confirmed that the influence on the possibility of accidents differs by age group among the aged.

The number and age of elderly drivers are continuously increasing according to the extension of the human lifespan. Therefore, in transportation, efforts are being made to differentiate and manage elderly drivers by age group. This study aims to identify the factors affecting the crash severity of early and late elderly drivers, compared to middle-aged drivers, and to identify the characteristics between these groups. Crash data that occurred on nationwide roads for the past 5 years (2017-2021) was applied. Unlike previous studies, this study only targeted drivers in their 40s and older, when presbyopia begins: middle-aged driver (40-64), early elderly driver (65-74), and late elderly driver (75+). As a result of logistic regression analysis, a total of 18 variables were found to affect serious injuries including fatalities in early and late elderly drivers. Most of these variables appeared to lead to severity more sensitively in the late elderly group. The results of this study are expected to be useful as basic information for establishing traffic safety policies for elderly drivers in the future.

The Implementation Semi-Public Management System of Intra-City Bus brings improvements of the position stability, work environment and welfare of the bus drivers. As these benefits prevent drivers' job changes, average age of the drivers increases. Some side effects such as fatality increase after the implementation of the new system are becoming social problems. To minimize such problems, it is necessary to prepare the measurements reflected drivers' age increase and driving characteristics of old drivers to decrease traffic accidents of intra-city buses. The existing measurements are mostly simple policy. To get over such limitations, this study grasped driving characteristics by surveys and driving aptitude test targeting old drivers and non-old drivers who brings about traffic accidents actually. As a result, the characteristics of the old drivers were understood precisely. The measures of decrease of the traffic accidents are suggested by the analysis of the behavior characteristics of the old drivers through the structural equation model.

교통사고는 인적피해, 물적피해, 사회적피해와 거시적으로는 심리적 피해까지 일으키며 많은 비용을 발생시킨다. 이처럼 교통사고로 인해 발생하는 다양한 피해요소를 비용으로 환산하여 추정하는 것은 교통안전사업의 절감편익을 산정하거나 기타 교통관련사업의 효과를 적용하기 위하여 활용할 수 있다. 하지만 현재까지 이루어진 사고비용 산출에 대한 연구론은 1당사자와 2당사자 구분없이 사고 전체를 아우르는 피해비용을 산출하는 방식의 접근 방법과, 사상자 1인 기준으로 발생되는 피해비용을 산출하는 방식의 접근 방법으로 나뉘며, 두 접근방법 모두 비용분석의 대상을 단일 객체로 간주하고 분석하는 한계를 지니고 있다. 이에 본 연구에서는 특정한 상호작용효과가 있을 것으로 예상되는 고연령 구간을 확인한 뒤 고연령 구간과 전체 연령 구간 사이에서 발생된 사고를 비교분석하여 1당사자와 2당사자가 모두 고연령 구간일 때 추가로 발생되는 사고비용을 산출 및 검정함으로서 고령자 사고감소효과 및 절감편익에 활용될 수 있는 상호작용 효과에 따른 추가 절감편익을 산출하였다.
