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.

This paper presents the potential of in-vehicle data recorder system for monitoring aggressive driving patterns and providing feedback to drivers on their on road behaviour. This system can detect 10 risky types of drivers' driving patterns such as aggressive lane change, sudden brakes and turns with acceleration etc. Vehicle dynamics simulation and vehicle road test have been performed in order to develop driving pattern recognition algorithms. Recorder systems are installed to 50 buses in a single company. Drivers' driving behaviour are monitored for 1 month. The drivers' risky driving data collected by the system are analyzed. Aggressive lane change in 50km/h below is a cause in overwhelming majority of risky driving pattern.

The purpose of the present study was to present evidence for driving interventions for the elderly by conducting programs that can improve visual perception and cognitive function in a driving simulator for elderly drivers and analyse their effects. Three elderly subjects who were 65 years or older, did not have physical and cognitive impairments, and were able to drive themselves participated in the present study. A total of 12 intervention sessions, of which subjects participated in 10 sessions of nine different visual perception and cognitive function programs available in a driving simulator, were conducted and pre- and post-program assessments were conducted (two assessments in total). The assessments included the evaluation of visual perception, frontal lobe function, concentration, safe driving behaviour, and self-efficacy. The results showed positive effects of the driving simulator program on the visual perception, frontal lobe function, concentration, safe driving behaviour, and self-efficacy of all subjects. Changes in the simulator results showed remarkable improvement in the response evaluation, judgment evaluation, and predictive power evaluation, but showed difficulties in interference tasks and depth perception in common. The results showed positive effects of driving simulator training on the driving ability of the elderly, and consistent provision of such training is expected to improve the quality of life of the elderly by securing the safety of driving and actively supporting social participation.

A conceptual model represents an understanding of a system that is going to be developed, which in this research, a driving simulation software to study driver behavior at signalised intersections. Therefore, video observation was conducted to study driver compliance behaviour within the dilemma zone at signalised intersection, with regards to driver's distance from the stop line during yellow light interval. The video was analysed using Thematic Analysis and the data extracted from it was analysed using Chi-Square Independent Test. The Thematic Analysis revealed two major themes which were traffic situation and driver compliance behaviour. Traffic situation is defined as traffic surrounding the driver, such as no car in front and behind, car in front, and car behind. Meanwhile, the Chi-Square Test result indicates that within the dilemma zone, there was a significant relationship between driver compliance behaviour and driver's distance from the stop line during yellow light interval. The closer the drivers were to the stop line, the more likely they were going to comply. In contrast, drivers showed higher non-compliant behavior when further away from stop line. This finding could help in the development of conceptual model of driving simulation with purpose in studying driver behavior.

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.

Pile driving formula, wave equation analysis of pile driving(WEAP) and dynamic pile loading test have been known to useful tools to appraise the behaviour of pile driving. This paper reviews basic theories of three methods and gives some suggestions to apply them to practice. And also some cases on application of the methods to the sites are discussed in this paper. It appears that it is inevitable for engineers to be experienced well so that the methods can be regarded as useful tools.

Two experiment are planed to identify driver's safe driving behaviour by curve radius, road surface condition in curve section. At four-lane and two-lane road, conducted experiments are check on driver's feeling of safety that 30 subjects do not feel discomfort. And using the data from these experiments, this study compare physical speed (not slipping, fall our of the road) with safety driving speed(drivers felt a comfortable and safe speed) each curve radius and fiver road surface condition(drying, wet, rain, snow and ice). As a result, safe driving behaviour factors that are derived to curve radius of 100m units, five road surface conditions enable to represent quantitative analysis of driver's discomfort. This study will develop road design method and evaluation reflected ergonomic aspects.

In this study, electronically controlled automatic transmission adopted on a subcompact model in the market was modelled, and the driving performances of the transmission were simulated with the models. Kinetic and dynamic models of working components are established. The driving simulation program is developed with those models, and the various driving conditions are analyzed. With the results, the dynamic behaviour of the engine and the automatic transmission is easily understood. Especially, the transient performances of torque converter and clutches are deeply analyzed. Skipping the vehicle road test by using this analyzing tool, we can expect the cost down and the reduction of the development period of automatic transmission.

The type of physiological stress involved in driving is probably complex, and a comprehensive study involving recording of physiological signals such as electrocardiogram(ECG), electromyogram(EMG). Changes in relevant Physiological parameters, such as ECG, EMG, reflected changes in driver status. In order to derive the mental and physical load of driving a motor vehicle from driving behaviour alone it is necessary to establish the relationship between changes in a driver's physiological parameters and behavioral parameters. In this study, we choose two different condition and investigated driver's status using HRV analysis method. Many previous studies have shown that increasing driving time causes a variation of HRV signal.
