도로교통의 안전 확보와 사고 예방을 목적으로 운전자나 보행자에게 필요한 정보를 제공하기 위해 경찰청에서 규격 또는 지침으로 제정하여 노변에 설치되는 교통안전시설 장치는 교통신호정보를 받기 위한 통신선과 함께 장치 구동을 위한 전원선을 개별로 시공해야 하기에 시공 비용의 절감과 함께 다종·다형의 장치에 대하여 통합적인 관제, 확장성, 유연성에 대응할 필요성이 제기되고 있다. 이에 본 논문에서는 이더넷 통신을 기반으로 전원 공급이 하나의 케이블로 가능한 이더넷 전원장치(PoE) 기술과 IoT 프로토콜인 MQTT를 이용하여 다종·다형의 교통안전시설 장치를 통합관제하고, 확장성과 유연성을 가지는 교통안전시설 장치 통합 시스템을 제안한다.

In order to trust and use autonomous vehicles, safe driving on the road must be guaranteed. For this, the first infrastructure to be equipped with autonomous driving is traffic safety facility. On the other hand, autonomous vehicles(Level 3) and general vehicles are driving on the road, it is necessary to additionally manage existing general traffic safety facilities. In this study, a field management system for traffic safety facilities based on autonomous driving infrastructure was studied, and a pilot field management system was implemented in the demonstration area(Pangyo). The pilot system consists of a GNSS(Global Navigation Satellite System) receiver, a field management equipment, and a field management app. As a result of field demonstration,, it was confirmed that traffic safety facility information was easily transmitted and received even in downtown areas and that could be efficiently operated and managed. It is expected that the results of this study will be used as reference materials for the spread of autonomous driving infrastructure to local governments and infrastructure construction in the future.

교통소통과 안전을 위해서는 체계적이고도 획일적인 교통안전시설물의 설치 및 관리가 요구된다. 앞으로 교통안전시설물에 많은 투자가 절실히 요구되며, 계속 늘어나고 있는 자동차등 여러 가지 교통여건을 감안하면, 교통안전시설물에 대한 수요는 더욱 증갛살 것으로 예상된다. 지리정보시스템 (GIS)을 활용하게되면 급증하는 교통안전시설물의 조사 및 유지·관리업무를 제한된 인력과 예산으로 수행할 수 있게된다. 그러므로 교통안전시설물의 체계적인 유지·관리를 위해선 GIS의 활용은 필수적이라 하겠다. 또한 신설 및 교체수량의 정확한 예측 등과 같은 효과를 거둘 수 있어 효율적인 예산을 집행할 수 있게된다. 본 연구는 지리정보시스템 (GIS)을 이용하여 교통안전시설물 유지·관리 시스템 개발에 목적이 있으며, 특히 개발된 시스템은 실무담당자 활용에 편의를 도모하는데 주안점을 두었다.

This paper attempts to find an improved organizational structure for operating the traffic safety facilities. Currently, police is in charge of the facilities while the local government is in charge of its budget. By doing so, many inefficiencies and problems occur in these things. A delphi technique is used to survey these inefficiencies. Problems, and improved role and organization by three expert groups in local government, police and university The survey results are analyzed by each expert group as well as by the total group. The multidimensional scaling technique is also used. The most preferable answer is to newly establish a traffic experts' agency under the local government. The second preferable answer is to set the current traffic police under the control of the local government.

항만건설 및 운영에서 해양교통시설의 설치와 운영은 해상충돌방지 및 안전에서 매우 중요한 인자이다. 그리고, 해상교통시설의 설치 및 운영은 IMO SOLAS 5장 제13조에 의하여 당국의 의무사항으로 규정되어 있다. 해양교통시설은 과거의 시각적(광학, 형상) 시설에서 AIS, DGPS 및 기타 전파표지 등을 활용한 e-Navigation의 개념으로 발전하고 있다. 그러나 해양교통의 자동화 흐름에도 선박의 안전한 항해를 위한 광파표지 및 형상표지의 역할은 여전히 절대적이다. 본 연구에서는 시각표지의 운영관리 효율을 향상시키기 위한 해양교통시설 서비스수준의 결정방법으로 해상교통관련 전체 시설을 하나의 관리시스템으로 조합하고 더욱 효율적인 시스템 관리방안으로서 해양교통시설 운영률을 제안하였다. 그리고, 선행연구에서 제안된 해양교통시설시스템에 관해 위험관리모델의 적용으로 검증을 수행하고 체계화시키기 위한 방안을 도출하고자 하였다.

This paper proposes a plan to improve the installation and operation of traffic safety facilities using a microscopic simulation by confirming the difference in the perception method and range of autonomous vehicles and human vehicles. In this study, the existing 『Traffic Safety Sign Installation·Management Guidelines』 was reviewed, and safety signs among traffic safety facilities were classified according to changes in vehicle behavior. Subsequently, for the classified facilities, the installation location of the traffic sign was changed through simulation experiments, and the optimal location was inferred to suggest an improvement plan. This study confirmed how traffic safety facilities installed based on the visibility of human drivers affect road efficiency and safety in mixed traffic flow with autonomous vehicles and human-controlled vehicles. The optimal location derived through this study is meaningful because it can be used as the basis for revising the guidelines on the installation and management of traffic safety facilities.

This paper studied safety benefit of operation-effectiveness analysis on marine traffic safety facilities. In the operation-effectiveness of marine traffic safety facilities the benefits can be divided as safety benefit, transport benefit, and other benefit. Safety benefit was produced as the loss aversion cost of marine traffic caused by the reduction of marine accidents after establishing and operating marine traffic safety facilities. First of all the reduction rate marine accidents was estimated to do it, and the detail model of loss aversion cost was constructed Then each variable in the model was defined and the method of computation presented.

There are many investment budget drafts in the filed of a road traffic safety. The traffic safety budget is spitted into following three major areas: 1) traffic safety facility (Engineering), 2) traffic enforcement (Enforcement), and 3) traffic safety education & public relation (Education). The three area are known as so-called 3E policy. This study investigates the effect of the investment in the 3E policy on the reduction of traffic accidents analyzing the data annually collected from the 15 local governments during 1992 to 2007. The analysis employing the traffic accidents as the dependent variable reveals that the effect of the investment is higher if same amount of investment is made on areas of the traffic safety education and public relation than the area of facility improvement. The similar conclusions are resulted from the separate investigation of traffic accidents data by 6 different types. All the results consistently indicate that the current traffic safety investment being primarily made on traffic safety facility needs to shift to the areas of traffic safety education and public relation budget.

In this paper the benefit was forecasted for traffic safety facilities to be constructed along the inland waterway between Phnom Penh and Chong Kneas(Siem Reap) port in Cambodia. First of all, the number of cruise ships passengers and cargo volumes were predicted. Second, the traffic volume of the cruise ships and cargo ships were calculated according to the prediction. Last, the safety benefit of traffic safety facilities was forecasted with the traffic after surveying the waterway accidents. The other benefit was also presented by converting the effect of relieving the emotional burden of navigators into currency value. Accordingly the entire benefit was estimated to be $14,990, $20,950 and $28,540 for pessimistic, moderate and optimistic prospects, in 2011. And then the entire benefits are calculated as $28,320, $63,060 and $95,230 for each prospect in the final estimation year 2020.

최근 항만을 비롯한 연근해에 해상교량이 계획되어 다수의 해상교통안전진단이 수행되고 있다. 해상교량의 안전진단에서 핵심적인 요소는 해상교량의 형하고와 주경간장에 따른 항로 폭이 될 것이다. 해상교량의 형하고와 항로 폭을 결정하는데 있어 어떤 선박을 대상선박으로 하느냐, 대상선박의 제원을 어떻게 볼 것인가에 따라 해상교량의 시설한계가 크게 달라진다. 따라서 본 연구에서는 최근 수행되고 있는 해상교량에 대한 해상교통안전진단에서 이슈가 되고 있는 사례를 분석하였다. 첫째 삼산 연육교의 대상선박은 대상해역을 통항하지 않은 유도탄고속함(570톤)과 통항빈도가 거의 없는 예인선열이 이슈가 되고 있다. 둘째, 사양-와교의 대상선박은 통항한 적이 없는 여수해양경찰서가 보유한 최대선박인 640톤급 517함을 대상으로 하고 있다. 이는 해상 교량의 시설한계의 문제만이 아니라 해상교통안전진단 사업인가 안전진단 보고서 제출면제 사업인가에 대한 논란을 야기할 수 있다. 본 연구에서는 다양한 여건의 해상교량의 안전진단에 대한 안전진단대행기관의 의견을 수렴하여, 추후 통일된 선박 및 선박의 제원에 대한 통일된 기준안을 마련하여 안전진단시 통일된 기준을 사용하기를 제안한다.
