Road sign is one of the road attached facilities to provide conveniences to motor drivers. The setup of location information according to the related regulation and the inclusion of various attributes such as place names, route numbers, symbols, bearings, distances to the place of interest distinguish the road sign from other facilities. These features give advantages to the informationization of road sign. Presently there established about 130,000 road signs on each class of roads, and about 280 road management offices have controlled these road signs independently, but there are plethora of ineffectiveness such as the lack of consistency, recognition, connectivity, and location suitability etc. These are the major factor of confusions rather than providing conveniences, and arisen a lot of public grievances. Accordingly, in this research the road signs throughout the nation were databased and the web-GIS based road sign management system was established to ameliorate the problems reveled. Since the road sign management system we developed reflected the demands of the persons in charge and users, the management effectiveness might be enhanced and the public inconveniences will be reduced.

간선도로의 유입부 설계에는 도로 표면에 떨어진 강우만을 고려하여 빗물받이 간격, 형태 등을 결정하고 있으나, 현실적으로는 간선도로와 연결된 소규모 도로에서 횡유입부로 유입되지 않는 유량이 간선도로의 침수를 가중시키고 있는 실정이다. 이러한 점들을 고려할 때, 침수피해에 의한 시민들의 재산을 보호하고 불편을 덜어주기 위해 소규모 도로의 합리적인 배수시설이 필요하며, 이런 배수시설로 부각되는 횡유입부의 차집효율을 분석할 필요가 있다. 본 연구에서는 횡유입부의 설계 실태를 조사하고, 현장조사를 실시하여 수리인자들을 실측하여, 실험장치의 제작과 효율적인 실험조건을 선정하였다. 도로에서 횡방향으로 설치되어 있는 빗물받이 유입구의 규모에 따른 가능 최대 차집유량과 그에 따른 효율을 분석하기 위하여 도로 종경사$(2{\sim}11.5%)$, 유량$(1.5{\sim}24{\ell}/sec)$, 빗물받이 유입구의 규모 및 형태(TYPEⅠ, TYPEⅡ)를 변화시키면서 실험을 실시하였다. 실측 자료를 분석한 결과, 도로의 종경사가 6%이상이 되면, 횡유입부의 차집효율이 급히 감소되는 것을 알 수 있었으며, 빗물받이 유입구 TYPEⅠ의 형태가 TYPEⅡ의 경우보다 차집효율이 현저하게 감소하고 있음을 알 수 있었다.

충북 단양은 우리나라에서 대표적인 산수(山水)의 고장으로 꼽힌다. 남한강과 소백산이 만들어낸 단양팔경은 국내에서도 내로라하는 관광명소다. 그야말로 도시생활에서 지친 몸과 미음을 치유할 수 있는 최적의 장소인 것이다. 하지만 그동안 단양을 찾는 이들에게는 조금의 불편함이 있었던 것도 사실이다. 단양IC에서 단양역까지 이르는 도로는 남한강(충주호)을 끼고 있어 최고의 절경을 볼 수 있는 드라이브 코스로 유명하지만 왕복 2차선에 불과해 주말, 휴가철에는 병목현상이 빈번했기 때문이다. 또 그만큼 교통안전 여건도 좋지 않았다. 이런 문제점들은 2016년 4월이면 완벽히 해소될 전망이다. 쌍용건설이 이 구간을 4차선으로 확장하는 건설공사를 한창 진행하고 있기 때문이다. 쌍용건설은 이룰 통해 도로이용자들의 교통안전을 확보하고, 지역 균형발전에 이바지한다는 계획이다. 때문에 이곳 현장에서는 무엇보다 안전을 최우선 가치에 두고 있다. 이곳의 안전관리가 어떻게 전개되고 있는지 찾아가 봤다.

One of the basic requirements for the most advanced countries would be the well-planned traffic infrastructures. For such traffic safety systems, foreign countries follow the current tendency to which they manage the traffic facilities and equipments based on the objective assessment for the state of every traffic safety facility in terms of Asset Management(AM). As the road safety facilities related among them are very diverse, and their functions are very important as well, the regulations and directions for installing them are enacted. However, despite the standards and directions for the installations, sometimes, the facilities are not installed in accordance with the standards, not only causing inconvenience to the users but also negatively affecting the safety for them. In the study, for the facilities in which the installation interval and height are standardized according to the designed speed and geometrical structure of the road among the various road safety facilities, the image analysis model capable of measuring them with a line scanning camera was developed. In addition, the program systematically analyzing this was also developed and applied to the field and, as the result of that, the size and installation interval of the facilities could be measured fast and accurately.

The safety speed 5030 policy, which is currently being implemented nationwide, tends to increase citizens' dissatisfaction due to reduced mobility and inconvenience. In order to successfully promote the Safety Speed 5030 policy, it is important to collect various opinions of citizens who use roads by deviating from quantitative policy evaluation criteria such as traffic accidents and traffic speed. Therefore, in this study, citizens who use roads were classified into a driver group and a non-driver group, and civic consciousness analysis such as adequacy evaluation of speed limit, satisfaction evaluation of road service quality (MDS), and importance-satisfaction analysis (IPA) was conducted. As a result of the analysis of civic consciousness, in particular, satisfaction with mobility, economy, and environment was low. Accordingly, it was intended to promote the successful implementation of the Safety Speed 5030 policy by presenting measures to improve the speed limit and quality of road service for roads with low satisfaction.

Snow fall and icing on traffic roads in the winter season cause not only inconvenience but unexpected traffic accidents, so the proper measures are needed. The existing road information system is being installed for steep slope roads in mountain areas, however, it is not widely adopted because it is too expensive. In this paper, a novel and cost-effective road weather information system especially for snow fall and icing on roads is proposed. The system consists of digital temperature and relative humidity sensor, infrared temperature sensor, ultrasonic sensor, CMOS camera, and two types of control/communication board for ubiquitous sensor network to send the data to server. The server program including the decision making method with received data is also described. Experimental results are provided to prove the feasibility of the proposed system.

The embedded demountable shear connector was developed in preparation for replacement works due to deterioration and damage to the bridge panel of the PSC girder bridge which is a road infrastructure directly related to the safety and convenience of the people. The demountable shear connector minimizes crushing works in the demolition process of the panel, and it is easy to re-construct the shear connector for replacement work. The economic feasibility of the PSC girder bridge using the embedded demountable shear connector compared to the existing construction method was analyzed from the perspective of road users (people) by calculating and comparing the cost of road users caused by traffic blocking during each construction method.

Pedestrians have been exposed to dangerous traffic environments, in which walking spaces in a city decrease without improved facilities even though cars increase. Such poor walking environments are deadly dangerous to the vulnerable as well as the non-vulnerable. This study analyzed the road facilities use characteristics according to a type of vulnerability in order to improve traffic safety and walking environment for vulnerable pedestrians. This study surveyed the vulnerable in terms of issues that they encountered on existing walkways and conducted the analytic hierarchy process (AHP), which took all quantitative and qualitative variables into account. The results of Level-3 analysis were showed that the elderly and the disabled were partially similar; both felt most inconvenient at enter-exit sections, steep walkway and bad paved walkway. Unlike those results, people with children and/or infants answered that overpass or underpass walkways without lifting facilities were most inconvenient walking environments.
