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.

Energy absorption facilities installed on roads should follow the performance standards of the real-car crash test of 'Installation and Maintenance Guidelines for Roadside Safety Facilities'. However, due to different installation conditions, such as differing structure widths on roads, some energy absorption facilities do not provide adequate performance. In order to apply varied environments on roads, an energy absorption structure was designed in this study with 150 mm height and four layers of W-shape guardrail at 200 mm intervals, and the performance was verified using LS-DYNA computer simulation. Through a real-car crash test, the performance of the facility designed by LS-DYNA was tested and was found to meet the performance of the CC2 category for crash cushions. The conclusion of the comparison demonstrates that the simulation and the real-car crash tests are both significant.

공공시설 중 도로계획의 경우 건설과정 및 건설 후의 소음 및 오염 등의 환경 사회적 비용 및 주행성 안전성 등 요소의 평가 등을 수량화가 어려운 대표적 비용으로 들 수 있는데 본 연구에서는 이러한 수량화가 어려운 비용 효과들을 포함하여 고려한 도로노선계획결과를 정보계측기법과 지리정보시스템을 이용하여 '정보량'이라는 통일된 단위로 표현하고, 기존 시설물과의 관계로부터의 '정보편익' 개념으로 평가하였다. 정보계측기법은 인간은 언어를 통하여 모든 사물을 정보로 표현하므로 '정보'라는 통일 된 단위를 사용하여 모호한 가치를 평가해 보고자 하는 방법이며, 따라서 공공시설의 계획과정에서 최적해를 찾기 위한 비용, 편익 및 환경 사회적 요소 등의 정량화되기 어려운 가치를 평가하는데도 사용될 수 있을 것이다. 정보계측기법과 지리정보시스템을 이용하여 도로건설시 발생하는 비용과 직접효과를 고려하기 위하여 시설정보계측모형을 개발하였으며, 도로 주변 시설간의 편익을 고려하기 위하여 시설정보편익모형을 구성하였다. 개발된 모형을 실제 도로계획 사례에 적용한 결과 비용과 직접효과만을 고려한 시설정보계측모형에서는 기존의 도로설계와 유사한 결과가 도출되었으며, 시설정보편익모형에서는 기존의 도로계획 평가에서 고려할 수 없었던 요소들에 대한 고려가 가능하였다.

With the advent of the 4th industrial revolution era, interest in autonomous driving technology is increasing. Accordingly it is necessary to seek safe driving by recognizing surrounding situations using sensors attached to autonomous vehicles along with the applicability of existing traffic facilities to autonomous driving lanes and the utilization of HD maps. In this study, in order to deduce the role of sensor only physical facilities which recognized through a laser scanner on an autonomous vehicle developed to improve road and traffic infrastructure, through comparative analysis with existing road facilities such as road signs, safety signs, and gaze guidance facilities. Sign facilities can promote driving safety by allowing autonomous vehicles to perform specific actions directly. In order to promote safe driving by recognizing sign facilities by using sensors for autonomous vehicles, it is necessary to prepare standards for installation, management, and use, and it is considered that management and supervision should be carried out continuously according to the standards.

Recently, the paradigm of road policy has been focused on user safety. Recently, the number of road facility improvement project has been continuously increased but the economic feasibility (B/C ratio) is insufficient. Therefore, it is necessary to select a reasonable road improvement project through accurate and objective analysis of the road safety evaluation. In this study, to develop a new road safety evaluation method, data were collected based on the current road safety evaluation method for 75 routes including national roads and provincial ones. Based on the collected data, problems were analyzed and utilized as the basic factors of the new road safety evaluation method. Therefore, in this study, traffic accidents were reflected as a general evaluation item by weighing to solve these problems, and the evaluation items were added from experiences and ideas of the local public officials. For each evaluation item, a reasonable weight was determined through AHP (Analytic Hierarchy Process) questionnaire evaluation with highway experts. In addition, the safety index was determined based on the evaluation criteria for each evaluation item. The criteria for evaluating the danger zone are determined by the overall safety index. Finally, the criteria for selection of road improvement projects based on the overall risk level were derived.
