        In line with the trend of global transport volume which has increased rapidly over the years, internal transportation in seaports is always conducted with high frequency. Thus, there is always much potential for traffic jams as well as high transportation costs and emissions. Many efforts have been initiated to streamline the inter-terminal container transport (ITT) through the development of automated vehicles and equipment as well as using private transport facilities to overcome these limitations. The purpose of this paper to develop a framework to design, analyze, and validate the efficiency of a new ITT system in a port area based on the monorail network and automatic vehicles. First, the number of shuttles and loaders was determined depending on the transport demand scenario. Next, a simulation model was applied to evaluate the system performance as well as gain more insight into the working process of the ITT system. Finally, by setting goals for the performance indicators, the results showed that the system was highly efficient with 100% of the containers delivered to their destination on time. Besides, a series of other performance tracking was provided to provide insight into the system's capabilities.

        영상처리기법(Visible 카메라)을 이용하여 A지역 열차 차량의 주행륜, 안내륜 및 집전슈의 거동상태와 차량의 전 궤도 주행에 대한 주행특성(상하, 좌우 변위)을 30Hz로 측정하여 모노레일 구조물의 노면상태를 평가하고자 한다. 열차 차량의 운행에 따른 상하, 좌우 거동상태, 안내륜 및 가이드레일의 거동상태, 주행륜 및 주행면의 거동상태, 주행륜 및 주행면의 거동상태 및 전차선 및 집전슈의 거동상태를 측정하여 정량적인 데이터를 도출하고자 한다. 차량의 주요 측정지점 7개소에 대해 고해상도 Visible카메라를 장착하여 약 6km구간을 주행시간 동안 1회 측정하고, 녹화된 영상데이터를 분석하였다.
