As the high performance computer system increases, improving of reality and usefulness causes the virtual environment of simulator to be used widely as training and assessment tool. Although some domestic companies have developed train driving simulators since about mid of 1990s, accumulation of technology and experience is not yet sufficient compared to foreign makers. This paper describes system composition, training and assessment regimes for high level train driving simulator. When the subsystems are designed, comprehension of train system is emphasized and the functions that simulator should provide are discussed.

Vehicle simulators provide an effective and safe environment for training operators. Many vehicle simulators have been developed but only a few have reached the stage of widely available tools; these tools are usually expensive and run on workstations only We have developed a low-cost, PC-based excavator simulator for training operators. Currently the simulator is dedicated to operating the boom, Em, bucket, and driver's cabin for digging by the action of the operator on two joysticks. This paper presents the implementation of the excavator simulator and some implementation results.

The purpose of this paper was to investigate various factors influencing the intentions of drink-driving from multiple perspectives, in order to uncover ways to reduce the number of motor accidents caused by drink-driving. We examined sociopsychological aspects as well as driver's life styles such as smoking habit and exercise habit. Perception of behaviour controls among drink-driver' sociopsychological characteristics had the highest influence on the intentions of drink-driving, followed by influence of smoking and exercise on the intentions of drink-driving. This finding indicates that driver' life style such as smoking habit or exercise habit influences more on the intentions of drink-driving than attitude toward drink-driving or subjective regulations, which affirms that driver' life style such as smoking habit or exercise habit has significant effects on the intentions of drink-driving. Therefore, it is concluded that rehabilitative curriculum for drink-drivers should include a program to diminish drink-driving through nonsmoking and exercise habit.

Eco driving is a strategy to reduce energy consumption and greenhouse gas emissions from motor vehicle. However, it has not received much attention until recently. Psychological studies on this issue have been limited and the majority of existing studies have primarily been based on engineering and educational approaches. This study examined the effects of a self-management technique on two driving behaviors: speeding and putting the gears in neutral while waiting at the signal. The self-management technique consisted of three behavior interventions: goal-setting, self-monitoring, and reward. Three drivers participated in this study. An AB multiple baseline design across participants was adopted. Results showed that the self-management technique was effective in increasing both driving behaviors. Implications of the present findings and suggestions for future research were discussed.

Driving after drinking is highly likely to cause accidents due to lack of responsibility and poor judgment. South Korea is seeking a sentence for accidental drinking accidents. The suspended jail term for drunk drivers accounts for more than 70 percent of the total. However, those who come to the probation office during the probation period are involuntary, subject to little motivation for change, and the large-scale, collective, and short-term education offered to them is limited in preventing re-off. In addition to small group and long-term education, we conducted intensive short-term interventions to see changes in drinking habits in three months. In the long run, the effectiveness of drinking control will be demonsstrated, making a difference in improving the programs offered to drunk drivers in the future. Drunk driving accouts for a very high percentage of the causes of traffic accidents, which, like many countries around the world, should make efforts to prevent and punish drunk driving.

교통 체증은 차량 이용이 대중화된 지금 많은 문제를 야기하고 있다. 교통 정체로 인한 시간 허비, 장시간 운전으로 인한 운전자의 피로 증가, 매연 배출로 인한 환경 오염 촉진 등 교통 체증은 사회적으로 무시할 수 없는 여러 문제들을 불러온다. 이에 본 연구는 신호 체계 개선에 초점을 두어 유전 알고리즘을 이용한 도시 규모의 유동성 연동 신호 체계를 구현하고자 하였다. 이를 위하여 교통 시뮬레이션 프로그램 SUMO를 이용하여 실험 환경을 조성하고, 4개의 사거리와 16개의 사거리, 그리고 선릉역 인근의 실제 도로망에서의 최적 신호 주기를 탐색하였다. 실험 결과 4개의 사거리의 경우 유전 알고리즘 적용 전의 초기 설정에 비해 자동차들의 평균 이동 시간이 31.1% 감소, 16개의 사거리의 경우 6.2% 감소, 실제 도로에서는 1.1% 감소함을 확인할 수 있었다. 따라서 유전 알고리즘을 이용한 새로운 교통 체계는 교통 정체를 완화하는 효과가 있으며 본 연구를 실제에 적용한다면 도시 규모의 도로망에서 시간대 별로 교통 흐름을 최적화하는 맞춤형 신호 주기를 구할 수 있을 것이다.

The purpose of this study is to analyze the deterrence effect of traffic safety education on DWI(Driving While Intoxicated) offenders which is proposed as a incentive policy measure. For the analysis, 3512 drivers whose licenses were suspended due to DWI offence within the jurisdiction of Seongnam city in 2003, and whose driving behavior were traced for 5 years are collected. MOEs used in the study are the number of repeated DWI offence and DWI abidance duration. The statistics of analysis of covariance are used to compare the deterrence effectiveness of traffic safety education by adjusted means between groups. The results show that compared to uneducated group, educated group reveals to make less number of repeated DWI offence with longer DWI abidance period The resulting statistic also shows that active participation in the discussion during the class is more effective than just giving lecture. The former way for education can further reduce the repeated DWI by 12% and increase DWI abidance duration by 5.7% than the latter.

This research wished to risk type and examine closely driver special quality and relation of traffic accidents by occurrence type of traffic accidents and traffic accidents seriousness examine closely relation with Severity. Fractionate traffic accidents type by eight, and driver's special quality for risk group's classification did to distinction of sex, vehicle type, age etc. analyzed relation with injury degree adding belt used putting on availability for security the objectivity with wave. Used log-Linear model and Logit model for analysis of category data. A head-on collision and overtaking accident, right-turn accident are high injury or death accident and possibility to associate in relation with accident type and seriousness degree. In risk group analysis The age less than 20 years in motor-cycle driver, taxi driver in 41 years to 50 years old are very dangerous. The woman also was construed to the more risk group than man from when related to car, mini-bus, goods vehicle etc. Therefore, traffic safety education and Enforcement for risk group that way that can reduce accident that produce to reduce a loss of lives at traffic accidents appearance a head-on collision and overtaking accidents, right-turn accidents should be studied and as traffic accidents weakness class may have to be solidified.

There have been sustained developments of advanced technologies using traffic safety facilities recently and techniques for identifying failure modes and devices which could result in fatal outcomes. The purpose of this research is aimed at improving the driving conditions in advance through analyzing the IT convergence, driving education, researches for vehicles, field of construction and robotics. The researchers evaluate on usability tests of the driving with 26 candidates through focusing on safety, convenience, efficiency, effectiveness. Using specialized LED panel to enhance driving performances of disabled people are for cautious road conditions like foggy weather or heavy rain. As a result, there were improvements in the driving conditions, and candidates reported this system was helpful. It allows them for maintaining proper driving all times and was especially informative for people with low vision or visually impaired. This system plays a pivotal role as a prevention mechanism not only for regular drivers but also for further delict of traffic violations or accident offenders who already have former record on tort.
