In the study, evaluation indicators that should be considered in applying traffic calming schemes were developed, and it was intended to analyze the importance of indicators that should most considered in evaluation traffic calming scheme through AHP analysis on the basis of it. The result of the study is summarized as follows. The result of evaluation indicators may be summarized by dividing into residential area and commercial area. In category, the safety is shown to be more important than other indicators in the analysis when evaluation (residential area is 0.514 and commercial area is 0.439). Importance of evaluation indicators was analyzed in order Average Vehicle Speed, Traffic Accident Severity, and Pedestrian Separation. Residential areas to help keep the safety of pedestrians 'Average Vehicle Speed' as the major indices were derived. In commercial areas were analyzed as an important indicator Pedestrian Separation. Because there are so many pedestrians. When applying the effect of Traffic Calming, residential is greater than the commercial area.

In the study, planning indicator that should be considered in applying traffic calming technique was derived, and it was intended to analyze the importance of indicator that should most considered in planning traffic calming technique through AHP analysis on the basis of it. The result of planning indicator may be summarized by dividing into road section and crossing section. In road section, hump (0.35) for equipment stimulating reduction of speed, hump image/fort (0.31) for visual control equipment, and slalom type road (0.52) for chicane, and bollard (0.47) for blocking passing route are shown to be the most important and come before anything. In crossing section, signal indicator (0.33) for visual control equipment, rumble strip (0.44) for equipment stimulating reduction of speed, zigzag type road (0.65) for chicane, and blocking going straight at crossing (0.45) for blocking passing route are shown to be the most important and come before anything. The result of the study is judged to be used for basic material in applying traffic calming technique and establishing policy hereafter.

Recent interests in both vehicle emissions and public health have facilitated the development of more eco-friendly transportation systems. This study proposed an integrated simulation approach for evaluating the effectiveness of speed management strategies from the various perspectives including safety, operational efficiency, and environmental compatability. Those simulation methods include driving simulation, traffic flow simulation, emissions simulation, and air dispersion simulation. An essence of the proposed simulation framework is to create the systematic connection of each simulation method toward the evaluation of effectiveness of speed management strategies. As an example, chicane and speed hump in residential area were evaluated by the proposed method. It is expected that the proposed simulation-based approach would be effectively used for the decision-making process in selecting better alternatives considering both safety and public health.

In order to calculate the optimum installation interval between a speed hump and hump type crosswalk that are installed continuously in succession, this study examined the speed of a vehicle that passes different intervals between speed humps and hump type crosswalks from the approach section of a roundabout having a maximum speed limit of 30km/h; analyzed the effects of speed humps and hump type crosswalks installed continuously in succession on vehicle driving speed; and simulated the optimum installation height of hump type crosswalk. As a result, the following conclusion was drawn. First, it was found that the optimum interval between a speed hump and hump type crosswalk, which are the representative traffic calming techniques for reducing vehicle speed, to control vehicle speed under 30km/h is 30m. Second, as a result of comparing the deceleration of a vehicle that pass hump type crosswalks, it was found that if the installation interval is 65 m and above, a speed hump and hump type crosswalk had no effect. Therefore, it is desirable that the maximum installation interval between a speed hump and hump type crosswalk for controlling vehicle speed within a fixed road section should not exceed 65m. Third, the analysis showed that the optimum installation height of hump type crosswalk is 6-8cm in case vehicle speed at the approach section is 20km/h or lower, 8-10cm in case of 30km/h, and 10cm in case of 30km/h or higher, respectively. Fourth, even at a road section on which a speed hump and hump type crosswalk are installed, speed reduction effects may sometimes be insignificant due to a driver's studying effect, traffic conditions and so on. Thus, it is judged that speed reduction effects will be greater if several traffic calming techniques such as speed hump, chicane, and choker are applied at the same time. Therefore, in case of applying traffic calming techniques for the purpose of reducing vehicle speed in order to promote pedestrian safety, the composite application of several techniques should be considered.

우리나라 해역에서 선박의 대형화, 고속화와 선박교통량의 증가 및 항만과 해양개발 등으로 해상교통 환경은 급속하게 변화하고 있으며, 항로의 좌 우 측방 한계 표시, 항행위해요소의 표시 등의 용도로 사용되는 부표류는 항만, 연안해역 및 내륙수로에서 통항 선박의 안전을 위하여 그 수요가 점진적으로 늘어나고 있다. 변화하는 해양교통 환경에 능동적으로 대처하고 부표관리 업무의 효율성을 증대하기 위하여 경량화, 내부식성, 저비용 등 장점으로 정온도가 유지되는 항내나 내륙수로 등에서 국제적으로 항로표지용 부표로 이용되고 있는 플라스틱 부표의 국외 개발 동향, 제조 방법 및 시제품의 특성 평가를 통한 기술 향상 방안에 대하여 기술하였다.

이 연구는 보행우선구역 사업이 얼마나 목적을 달성하고 있는지 평가하고 분석하는 것이 목적입니다. 연구결과 보행우선구역 사업으로 방문객이 증가한 것을 확인 할 수 있으며, 상권의 영향력이 사업 전보다 더 광역화 된 것을 알 수 있습니다. 이에 따라 지역의 주차수요를 증가시키는 요인이 될 수 있기 때문에 주차공간을 별도로 확보하는 것이 바람직합니다. 또한 방문자 수가 늘어나고 체류시간이 길어지면서 주변의 청결상태가 열악해 질 수 있기 때문에 청결유지를 위한 노력을 더 기울여야 합니다.

본 연구는 탄소발생 문제를 줄이는 방안을 개발하고자 LTE모형(친환경토지이용, 녹색교통, 녹색환경)을 3가지의 유형으로 나누어 각각의 유형에 해당되는 탄소저감방안을 개발하고 사례대상지에 적용하였다. 그리고 계획요소를 대상지에 맞게 도출 한 후 시뮬레이션을 하여 탄소저감의 효과를 분석 하였다. 도출된 기법을 연구 대상지에 적용한 결과 높은 저감효과를 보이는 요소를 도출할 수 있었고, 경미한 수준의 저감효과를 보이는 요소도 도출할 수 있었다. 탄소저감 비율은 25.51%이었고, 그중에서 특히 교통정온화 계획요소가 95.42% 압도적인 비율로 저감효과가 있음을 알 수 있었다.
