Recently, starting with the deep underground road construction plan in Seobu Expressway, Korea, there area many studies on deep underground roads to be newly built. However, there is an extreme lack of safety standards, which does not consider traffic conditions and road driving characteristics. Therefore, this study reviewed safety elements to reflect in the deep underground road planning by analyzing driving stability of longitudinal tunnels with road environments, which resemble deep underground roads. For comprehensive analysis, the characteristics and causes of the accidents that have occurred in seven longitudinal tunnels with a length of 2km or over in Gangwon area, were collected. Specifically, geometric structures and facilities of each tunnel were investigated. Also, the present state of facility installation and the changes in driving speed of vehicles passing through each tunnel were observed to analyze the causes for the traffic accidents in each tunnel and accident reduction alternatives. It was revealed that the most frequent accidents in the tunnels resulted from the changes of traffic flow due to the abrupt speed reduction of forward vehicles, or the failure in speed control of following vehicles during the traffic congestion situation. Moreover, installing facilities such as plane and longitudinal curves, median strips and marginal strips seem to induce consistent driving speed. These results mean that for accident prevention, speed management must be preceded and there is a need to develop and introduce safety facilities actively to control the driving flow of forward and following vehicles.

운전자가 차량 조작에 개입하지 않고, 차량 스스로 주행하는 자율주행차량의 시대가 도래하였다. 자율주행차량 시대에서는 자율주행차량이 도로환경을 정확히 인식함으로써, 자율주행 차량의 안전성을 확보 할 수 있다. 그러나, 도로환경을 구성하고 있는 요소는 도로안전시설, 교통관리시설, 횡단구성으로 구분 할 수 있으며, 각각을 구성하고 있는 종류, 형태 및 규격은 다양하다. 따라서, 도로환경을 구성하고 있는 시설물 중에서 우선적으로 취득해야 하는 도로시설물에 대한 우선순위 결정이 필요하다. 본 연구에서는 전문가 설문 및 AHP(Analytical Hierarchy Process)기법을 이용하여 도로시설물 인식에 대한 우선선위를 결정하였다. AHP 분석을 위해 항목을 2계층으로 구분했으며, 1계층은 도로안전시설, 교통관리시설, 횡단구성, 2계층은 시선유도시설을 포함한 26개의 항목을 구분하였다. 분석 결과, 1계층에서는 도로안전시설, 교통관리시설, 횡단구성 중 교통관리시설이 가장 우선순위가 높은 것으로 나타났으며, 2계층에서는 방호울타리(도로안전시설), 교통신호기(교통관리시설), 중앙분리대(횡단구성)의 우선순위가 높게 나타났다. 또한, AHP 분석 기법을 이용하여 도출된 고정환경을 추출하는 사례를 제시하였다. 본 연구에서 제시한 도로시설물에 대한 우선순위 선정 결과는 자율주행차량을 위한 인식기술 지원 연구에 도움이 될 것으로 기대된다.

PURPOSES: This study is to investigate a generated traffic noise when vehicle pass over a transverse rumble strip at toll plaza of highway. METHODS: To investigate traffic noise at toll plaza of highway, Pass-by method which is the most common used for measuring traffic noise was adopted and the traffic noise at toll plaza was measured for 10 min per hour for 11hours(13:00~24:00). RESULTS: The measured traffic noise by pass-by method was changed as function of the transverse rumble strip configuration. Generally, the maximum difference among three noise measurement sections was 7 dB(A). It might be related with traffic speed. Also, the measured traffic noise was strongly generated from a passenger car which was 2 axle. It means that the most of traffic noise on the road is generated at tire/pavement interface of the passenger car. CONCLUSIONS: The traffic noise was strongly related with vehicle speed and transverse rumble strip configuration on the road. For driver safety, the transverse rumble strip is definitely necessary. However, the complaints from residents near highway was increased by traffic noise from transverse rumble strip. Therefore, To satisfy both safety and reduction of traffic noise, the development of configuration of transverse rumble strip is necessary in the further study.

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.

교통사고의 원인은 도로, 차량들의 물리적 요인과 인적요인으로 분류하고 있다. 이중 차량과 관련해서는 수많은 신기술들이 개발되었고 또 개발 중에 있으며 인적요인에 관해서는 최근 국내에서도 중요한 연구들이 수행 중에 있으나 그 결과를 실용화하는데는 더 많은 시간이 필요할 것으로 보인다. 도로요인에 관한 그 동안의 연구가 국도 등에 집중되었기 때문에 오히려 도로의 위계상 최상위 위치에 있는 고속도로를 중심으로 한 연구가 미진한 것처럼 비쳐지는 것도 부정할 수 없는 사실이다. 미국은 도로 안전도 증진을 목표로 IHSDM(Interactive Highway Safety Design Module)이라는 통합설계모듈의 개발을 추진 중에 있으며, 국내에서도 기초적인 연구가 시작되었다. 이러한 평가모듈의 개발에 필수적인 것이 도로설계대안별로 교통안전도를 계량적으로 평가하는 모형의 개발이다. 본 연구에서는 먼저 교통사고의 원인이 되는 도로요인 중 특히 도로선형과 교통사고와의 관계를 밝혀내기 위해 도로선형의 변화(선형개량, 도로확장)가 비교적 적었던 호남고속도로를 대상으로 고속도로의 선형요소와 교통사고와의 미시적인 관계를 규명하였다. 이를 위해 대상도로를 직선부, 곡선부. 완화곡선부 등으로 1차 구분하였으며 이들 구간의 선형요소와 지난 5개년('96년∼'00년) 간의 교통사고 자료를 데이터베이스화하여 모형산정에 이용하였다. 또한 도로선형 요소 중 특히 교통사고와 관계가 큰 것으로 분석된 몇몇 요소들을 이용해 고속도로 선형조건별 안전도평가모형을 구축하였다.

The purpose of this paper is to compare seafarers' behavior according to traffic conditions of a road and an onshore locations. Behaviors are classified into three categories: Skill-, Rule- and knowledge-based mode. Experimental data were collected using the questionnaires for navigators, working in a merchant ship. To compare the behaviors, we used the four analysis method; the degree of frequency, reliability test, correlation and linear regression. As a result of the study, it was found that Skill-based behavior shows more higher in the road traffic than the maritime traffic, and rule-based behavior shows more higher in the maritime traffic than the road traffic. Also, the behavior in the navigation situation showed statistical significance. Especially, in the case of Rule-based behavior, a high correlation between road and maritime was found. This study can be expected to apply to complementary system utilization between error management system of onshore and maritime traffic.

The article is devoted to analyzing the police influence on road safety formation. The globalization processes confirm the study's relevance, provoking population mobility and the need to increase freight traffic. The study aims to identify the factors that affect road safety and the activities of the police and the EU transport safety units. An empirical analysis using factor analysis, correlation analysis, and general scientific methods of cognition were carried out to achieve the goal. The analysis results found that the number of police officers affects road safety, but not in all countries, which confirms the importance of other factors. Based on the analysis results of the scientific literature, the factors affecting transport safety are legislative regulation, the use of innovative technologies, transport infrastructure, geography, and psycho-physical and emotional drivers factors. It has been proved that the police authorities and units cannot fully ensure transport safety in the European Union because the safety is formed by a complex of actions by the state and road users.

Owing to the need to establish a cooperative-intelligent transport system (C-ITS) environment in the transportation sector locally and abroad, various research and development efforts such as high-tech road infrastructure, connection technology between road components, and traffic information systems are currently underway. However, the current central control center-oriented information collection and provision service structure and the insufficient road infrastructure limit the realization of the C-ITS, which requires a diversity of traffic information, real-time data, advanced traffic safety management, and transportation convenience services. In this study, a network construction method based on the existing received signal strength indicator (RSSI) selected as a comparison target, and the experimental target and the proposed intelligent edge network compared and analyzed. The result of the analysis showed that the data transmission rate in the intelligent edge network was 97.48%, the data transmission time was 215 ms, and the recovery time of network failure was 49,983 ms.

도로의 안전성은 종단선형, 평면선형, 횡단경사(편경사), 노면온도 등 여러 가지 요인에 의하여 결정되며 이러한 각종 데이터는 도면으로 구하기 어렵고 실제 도면과 현황 데이터가 포장의 덧씌우기 등으로 달라지는 경우가 있다. 이러한 데이터를 측량하기 위해서는 많은 시간과 비용이 필요하고 차량의 통행이 빈번한 곳에서는 위험한 작업이 될 수 있다. 본 연구에서는 한국건설기술연구원의 도로 안전성 조사 분석차량인 RoSSAV(Road Safety Survey & Analysis Vehicle) 차량을 이용하여 주변 교통류 속도와 맞추어 차량에 부착된 GPS-INS와 회전식 레이저를 이용하여 도로의 횡단경사를 취득하고 분석을 통하여 도로의 안전성을 분석하고 도로의 안전성 개선방향에 대하여 제시하였다. 이를 위하여 측정된 값의 정확도를 비교하였으며 회전식 레이저데이터 처리 알고리즘을 제시하였다.
