The bikes are conflicted with the cars and the pedestrian at the intersection and the road with the bike crossing. To establish the bike signal at this section is one method to solve this conflict. According to the survey for the bike road status and the biker's characters which are crossing the road at the intersection, the bike crossing are established with beside the pedestrian crossing and most of the bikers are crossing the street by the pedestrian signal. Also, the bike queue which is waiting the signal change at the stop line was cleared before the closing the pedestrian signal. Considering the result of this survey, TOUCAN crossing signal type in England for bike signal at the place where the bike crossing are established with beside the pedestrian crossing, in which bike rider and pedestrian can cross by the pedestrian signal operation, is suggested. However, at the place where the bike crossing is apart from the pedestrian crossing, the bike signal which is connected to the vehicle signal is suggested. All these types of bike signals can be accepted for the present bike crossing equipments and the biker's characters and be adapted to the police standard traffic signal controller by adjusting the signal time only without any function change.

As the use of GIS becomes more widespread, the quality and source of data is becoming more of a concern among users. But accuracy is a component of quality, and the positional accuracy is a component of total accuracy. If only we consider the positional accuracy, simultaneously collecting technology of location and attribute information, whether it be manually, using conventional surveying method, GPS, or remote sensing, is a practical way of insuring that location and attribute information are correctly correlated. This study analyse the positional accuracy from a view-point of user and supplier, which is the considerations that can ensure quality level and continuously maintain the road and underground utility information. The positional accuracy of road and underground utility information are considered as two categories - expected accuracy of data collection procedure, required accuracy of data usage process. And the project manager must consider the cost/benefit view of data generation in order to determine the surveying method.

The ratio of Pedestrians in traffic accident fatality takes up 43% in Korea, which is 2.5 times as much as OECD's average. The traffic accidents features by road type shows that the fatality of the national highway posts the highest due to the accidents of pedestrians. Accordingly, the establishment of safety facilities for pedestrians is expected to increase on the rural roads for the prevention of pedestrian accidents. However, studies on pedestrians have been mainly focused on urban intersections. In Particular, studies on estimating the effectiveness of safety features for pedestrians are very poor. Thus, in this study. the Pedestrian accident probability model on four lane national highway was developed by using logit model. Also, this study analyzed and proposed the effect of facilities as a relative risk by using an odds ratio. As a result of the analysis, the Improvement of sight distance, installing sidewalks and lightings were proven effective alternatives for reducing the pedestrian accidents.

A traffic island, typical channelization facilities, is widely applied to newly road designs and black spots improvement projects as traffic safety measures. However positive effects of a traffic island for traffic safety have not been reported specifically. Accordingly this study analyzed the accidents reduction effectiveness and economics of installing traffic islands under various roadways and traffic conditions. For this purpose normality test, paired t-test and Wilcoxon signed rank test were applied to this study based on traffic accidents, roadways and traffic environments data for 3 years before and after improvement at 54 intersections. The results showed that most of traffic accidents were reduced significantly after installing traffic islands except when traffic islands were installed in outside of cities and farming regions where use efficiency is low, curve sections with poor visibility, poor alignment sections with acceleration/deceleration lanes, road sections where occurs conflicts frequently due to did not install of acceleration/deceleration lanes, and road sections where cross with single lane road.

For the application TBM tunneling method, Both tunnel design standard and case study designed & constructed in domestic and foreign have been conducted. According to the study, the number of lane and inner shape (single or duplex) vary depending on the volume of traffic. Also extra space located in the top and bottom of tunnel is used for a multipurpose such as ventilation, disaster prevention, maintenance and administration. To find area ratio according to the components of road TBM tunnel, a standard section was considered as a two-lane road. Then, the analysis of area ratio of this section which consists of components for clearance, extra space in upper and lower tunnel was carried on two widths of shoulder. In addition, after a structural analysis, a thickness requirement of lower slab which is essential for road tunnel was derived on a few supporting types. Through correlation analysis, the ranges of available cross-sectional area between slab thickness and lower extra space of the tunnel was presented.

기후변화로 인한 집중호우가 빈번히 발생하고 있으며, 도시지역에서는 호우에 의한 침수피해가 더욱 빈번히 발생하고 있다. 인구와 건물이 밀집한 도시지역은 불투수율이 높아 호우 발생시 홍수 위험도가 커지고 있으며, 침수에 의한 사유재산뿐만 아닌 사회기반시설에 대한 피해도 증가하고 있다. 도시는 건물과 건물 사이로 도로 네트워크가 복잡하게 설계되어있다. 이러한 건물과 도로들은 투수성이 떨어지며, 지하공간과 건물들이 발달하여 유역지표면의 가하학적 형상이 매우 복잡하게 변화하고 있다. 도시지역은 저류 및 침투능이 부족하고, 지역의 특성에 따라 내수배제시설이 부족하여 우수관망에 대한 우수배제의 의존도가 높으며, 호우에 의한 침수와 관거 월류에 의한 침수피해 발생시 우수는 도로를 따라 저지대로 흐르며 침수지역이 넓어지게 된다. 이와 같은 도시지역의 침수를 예측하기 위한 침수해석에는 지형의 높낮이, 형상을 고려한 예측이 필요하다. 특히 건물 및 도로망이 복잡한 지역일수록 지형이 정교하게 고려되어야 한다. 지형이 적절히 고려되지 않은 침수해석은 침수예상지역을 다소 과대 또는 과소하게 나타낼 수 있고, 침수심을 제대로 반영하지 못한 결과가 도출될 수 있다. 건물과 도로가 밀집된 도시지역에서 이러한 문제가 발생할 경우 예상치 못한 지역에서 침수가 발생하여 피해를 줄 수 있으며, 이는 곧 인명과 재산피해로 이어지게 된다. 본 연구에서는 과거 침수피해가 있었던 도림천 유역을 대상으로 지형자료의 해상도에 따른 침수분석을 실시하였다. 우수관망과 도시지역의 유출모의에 적합하다고 알려진 SWMM 모형을 활용하여 LiDAR(Light Detection And Ranging), 10m DEM, 1:1,000 수치지형도를 활용하여 지형상세도의 변화에 따른 침수모의를 실시하였다.

Collision behavior of clash cushion occurs for a second of less than 0.4sec usually so that it is too hard to calculate numerically. Therefore, for development of trash cushion, it rely on full-scale vehicle crash test without any design procedure. Occupant safety indices if calculated from acquired data by data measurement system and collision behavior of vehicle and crash cushion is filming using high-speed camera in the crash test. But practical ufo scope of high-speed camera is limited and it is not using to calculated the occupant safety indices or analyzed the energy dissipated mechanism of crash cushion. This work is to estimate to be suitable or not for compare the data from measurement system with the data from high-speed camera. And also it is to grope for practical use scheme to calculation of occupant safety indices or analysis of collision behavior.

In this study, the method of extracting road centerline's coordinate and road facilities is presented using RC helicopter photogrammetry system. From the survey of extracted road centerline, the errors turned out to be -0.117m ~ 0.103m on the X-axis and -0.014m ~ 0.009m on the Y-axis when RC Helicopter photogrammetry system utilized. By application of this system, hereafter, not only management of road facilities but also construction of DB would be enable which need positioning and design of alignment on the access is not easy area such as traffic congestion or toparchy area.

현재 도로화물운송을 분석하는데 가장 많이 사용되는 지표는 수송톤(ton)과 톤-키로(ton-km)이다. 하지만 이러한 두 지표는 도로화물운송체계를 설명하기보다는 단순히 운송실적을 나타내는 통계지표이다. 따라서 본 연구에서는 한국의 도로화물운송체계를 설명할 수 있는 운송단계, 총 운송거리, 순물동량, 평균운송거리 등의 4개 요소를 추정하였다. 그리고 한국의 도로화물 운송체계의 문제점을 진단하기 위하여 외국이 도로화물운송체계와 비교분석하였다. 본 연구에서 발견된 주요결과는 (1) 한국과 대만은 운송단계와 총 운송거리가 증가하고 평균운송거리는 감소하는 추세를 보였고, (2) 한국과는 대조적으로, 미국, 일본, 네덜란드는 운송단계와 총 운송거리는 감소하고 평균운송거리는 증가하는 변화추세를 보였으며, (3) 시계열 분석결과, 운송단계의 증가는 GDP대비 물류비와 운송비를 증가시키고 운송단계의 감소는 GDP대비 물류비와 운송비를 감소시키는 것으로 나타났다. 본 연구결과, 한국의 도로화물운송체계는 운송단계를 증가시키는 비효율적인 방향으로 진행되어왔고 이러한 운송단계의 증가는 GDP대비 물류비를 증가시키는 주요 원인임을 알 수 있었다. 따라서 한국의 도로화물운송체계를 개선시키기 위해서는 지능형 화물운송체계의 구축, 복합기능의 화물거점시설 확충, 화물자동차 운송업의 규제완화, 기업물류관리의 선진화 등의 정책을 통하여 불필요한 운송단계의 단축이 필요하다.
