This paper presents the traffic speed limit of heavy vehicles at each wind velocity region, which is based on their accident risk analysis under cross-wind. The variables for the accident risk analysis are overall height, overall length, intake weight, and friction coefficient of the road surface. It was confirmed from analysis results that the risk of overturning increased with higher overall height and length, and the risk of sliding decreased with higher intake weight. The risk of sliding was largest at the friction coefficient of 0.1, and the risk of overturning was lagest at friction coefficient more than 0.25. Finally, traffic speed limit was proposed by using the accident risk analysis.

본 연구는 고령운전자의 교통사고율 감소를 위하여 고령자의 운전패턴 인식을 통해 교통사고위험지수를 도출하고 그에 따라 운전면허증의 갱신 및 반납 정책에 반영하고자 실시되었다. 먼저, 고령운전자의 행동특성을 분석하여 교통사고를 유발하는 주요요인을 도출하여 교통사고 위험지수를 정의한다. 둘째, 자동차에 부착된 카메라, 거리센서와 스마트폰을 통하여 고령자의 운전패턴으로부터 교통사고 위험지수를 측정하는 방법을 제시한다. 마지막으로 컴퓨터 시뮬레이션으로 3개의 문턱 값을 도출하여 측정된 교통사고 위험지수로부터 사고위험도를 4단계로 판별하고 고령 운전자의 안전운전을 보장하기 방안을 제시한다. 제안하는 방법에 따라 고령운전자의 운전능력을 객관적으로 평가하여 운전면허 갱신주기의 재설정 및 자진 반납을 유도함으로써, 고령운전자의 교통사고 증가로 인한 사회적 비용을 최소화하기 위한 운전면허증 관리정책 수립에 적극 활용 가능할 것이라 믿는다.

본 논문에서는 GIS(Geographic Information System:지리정보체계)를 기반으로 도로의 선형조건을 이용하여 고속도로의 사고위험도를 파악하고 평가할 수 있는 방법을 개발하였다. 고속도로 평면곡선부에 대한 다양한 사고분석을 통해 도로의 선형조건이 교통사고에 미치는 영향을 규명하였으며. 이 결과를 토대로 사고예측모형을 구축하였다. 특히 사고영향인자를 규명하는 데에 있어서는 도로선형요소의 상호작용과 선형의 연속성을 반영함으로써 보다 현실적이고 객관적인 예측모형을 구축할 수 있도록 하였다. 아울러 사고예측모형의 추정결과와 사고자료를 토대로 고속도로의 선형조건에 따른 종합적인 사고위험도지수를 설정하고 이에 대한 평가기준을 마련하였다. 한편 주어진 도로선형조건에 따라 사고발생가능성을 예측하고 사고위험도를 평가하는 일련의 과정을 GIS와 결합하여 프로그래밍 함으로써 해당구간의 사고율 사고위험도지수, 위험도평가등급이 자동적으로 결정될 수 있게 하였을 뿐만 아니라 관련정보 및 평가결과를 시각적으로 제공하여 이용자가 보다 쉽게 이해하고 편리하게 사용할 수 있는 사고위험도 평가 프로그램을 개발하였다. 개발된 사고예측모형과 이를 토대로 설정한 사고위험도지수 및 위험도평가등급은 안전하고 비용-효율적인 도로설계에 도움을 줄 수 있을 뿐 만 아니라, 사고취약구간에 대한 대책 마련에도 이바지 할 것으로 기대된다.

Although Korea coastal area has the increasing potential marine accident due to frequent ship's encounter, increased vessel traffic and large vessel, there is no specific model to evaluate the navigating vessel's risk considering the domestic traffic situation. The maritime transport environmental assessment is necessary due to the amended maritime traffic law. However, marine safety diagnosis is now carried out by foreign model. In this paper, therefore, we suggest a domestic traffic model reflecting the characteristics of korea coastal area and navigator's risk as we named PARK(Potential Assessment of Risk) model. We can evaluate the subjective risk by establishing the model and model output into maritime risk exposure system. To evaluate this model's effectiveness, we used ship handling simulation and applied, analyzed collision accident which occurred in korea coastal area. And also, we applied integrated to an ECDIS program for monitoring traffic risk of vessels with real time based AIS data and apply to evaluate traffic risk in busan harbor waterway. As a result, we could evaluate busan harbor waterway risk effectively.

현재 우리나라 간선도로의 서비스수준(LOS)은 차량의 평균통행속도를 기준으로 평가되어지고 있다. 이는 도로의 혼잡도 만을 기준으로 적용한 것으로 교통안전측면이 고려되지 않은 것이 현실이다. 합리적인 도로 설계와 운영을 위한 평가 지표라면 도로 이용자에게 영향을 미치는 제반 인자들을 보다 포괄적으로 포함할 수 있어야 한다. 교통안전과 소통측면을 총괄할 수 있는 변수로 사용자비용 개념을 적용하여 간선도로 평가방법을 모색하고자 한다. 사용자 비용을 효과척도로 하는 간선도로 평가도 가능하다는 것을 본 연구를 통해 알 수 있었다. 또한, 본 연구의 사용자 비용에 의해 평가된 간선도로 서비스 수준과 도로용량편람의 평균통행속도에 의해 평가된 간선도로 서비스 수준을 비교 분석하여 종합적인 서비스 수준 분석방법 여부를 가릴 수 있을 것이다. 이로서, 안전과 소통 측면을 모두 고려한 간선도로 평가가 가능함을 알 수 있었다.

Saigon Port within the port system of the Vietnam Maritime sector is one of the port having highest throughput and productivity in the country. The marine traffic of Saigon water ways is the heaviest in Vietnam and the number of marine accidents in this area are much higher than the others area in Vietnam. In order to reduce the risk of the accident in Saigon fairway, this paper concentrates on marine accident frequency in this area. The marine traffic and the marine accident were analyzed to find out the probability of vessel collision and the marine traffic risk. It follows that the main shipping route through Saigon fairway has the high risk of ship-ship collision.

Approximately 4,000 vessels including sea trial ships per day are passing, entering or departing from Korea coastal waterway. Sea trial ships have erratic navigating patterns such as quick turning, crash stop and do not communicate with other vessels in appropriate time, so sea trial ships are often to expose dangerous situation such as collision in heavy traffic area. To identify the sea trial vessel's risk factors, this paper surveyed marine traffic volumes for 7 days in Korea harbour & coastal waterway, and it analyzed marine accident rate and intended to identify the risk degree of passing vessels. After that, this researched how many sea trial ship's traffic and what is the sea trial risk among sea trial items. We also conducted survey questionnaire and identified risk factors of sea trial ship. So this paper aimed to enhance the safety of korea coastal waterway to prevent sea trial ship's marine accident.

As the risk of traffic accidents caused by mists emerged as a social problem, recently safety facilities to be prepared for mists are being actively installed when designing roads. But in some part, the facilities are being installed imprudently without analyzing the extent of occurrences of mists that would increase the risk of traffic accidents and appropriate countermeasures against the occurrences of mists are not being suggested. For that reason, in this study, first questionnaire surveys were executed on road users in order to draw the factors affecting the traffic accidents caused by mists, a mist traffic accident predicting model was developed and an accident seriousness determining model that can determine accident seriousness was developed. In this way, by extracting major factors affecting mist traffic accidents to grasp risk factors in roads to be caused by mists, safety of roads can be enhanced and traffic accidents in road operations can be decreased. As the affecting factors influencing mist traffic accidents, were extracted sightable distances, durations of mists and whether daytime or nighttime as major factors and the plan to install the facilities for the prevention of mist traffic accidents was suggested to prevent the traffic accidents to be caused by those factors and also the plan to operate roads considering sightable distances was suggested to solve the problem of insufficient sightable distances to be caused by mists was suggested. It is judged that the road safety in the areas where mists occur can be improved through foregoing methods.

This is a study to evaluate the effects of the safety of ambulance driving and traffic accidents and to provide statistic information for the various factors to reduce the ambulance traffic accidents. The major instruments of this study were Korean Self-Analysis Driver Opinionnaire. This Questionnaire contains 8 items which measure drivers' opinions or attitudes: driving courtesy, emotion, traffic law, speed, vehicle condition, the use of drugs, high-risk behavior, human factors. The total of 145 divers were investigated ambulance drivers in Taejon City and others(6 City) from 2000. 5. July to 2000. 11. July. The data were analyzed by the path analysis - with SPSS and AMOS package program. The result are as follows : 1. It have suggested that risk factors of ambulance traffic accident much affected with emotion and speed control on safety ambulance driving(Y(Accident) = $0.88{\times}1$(Emotion Control) + $0.92{\times}2$(Speed) - $0.46{\times}3$(Traffic Law)+E). 2. It have suggested that risk factors of ambulance traffic accident much affected with emotion and speed control on safety ambulance driving(Y(Accident) = $0.398{\times}1$(Emotion Control) + $0.500{\times}2$(Speed) - $0.263{\times}3$(Traffic Law)+E) by coefficiecial structural analysis.

Recently, occurrence of alcohol-involved traffic accidents is increasing while all the accidents by violation of law except drunk driving. Traffic accidents by drunk driving has a great external cost. In detecting drunk driving, blood alcohol content Many studies reported close correlation between blood alcohol content and traffic accidents by drunk driving. The risk of traffic accidnet increases exponentially as blood alcohol content increases. To control traffic accidents by drunk driving, decide target population. Heavy drinkers are few and responsible for a small part of the loss while casual drinkers are many and responsible for a large part of the loss. Casual drinkers need to be included in the targer population for the control of traffic accident by drunk driving. Stragegies to reduce the quantity of alcohol consumed, change the pattern of drink, such as frequency of drinking, raise of perceived risk of accident need to be sought.
