Since the opening of Gyeongbu Expressway, the first Korean expressway of 428km connecting Seoul and Busan in 1970, the total length of expressway exceeds 4,200km at the moment. The Expressway Traffic Management System (ETMS) started at the Seoul-Daejeon section of Gyeongbu Expressway in 1992 and it was expanded to the whole expressway network. Although the introduction of a successful traffic management system, the total recurrent congested sections below 40kph are 51 sections of 373km on expressways and the traffic congestion cost as a social cost reaches a total of 2.8 trillion KRW (about US $2.6 billion) only on the expressways. Measures to improve traffic congestion can be applied to expanding the supply of facilities and increasing the efficiency of facilities. Physical improvement, which means expansion and construction of roads, is cost and time constrained, and there is also a limit for the improvement of traffic operation. In order to maximize the effect of traffic congestion management, there is a need to harmonize the both, but there is still a lack of awareness of the importance of integrated traffic management in Korea. In this study, the concept of Integrated Traffic Management (ITM) on expressways integrating various individual traffic management techniques such as ramp metering, toll metering, and variable speed limit is proposed and the effect of the effect of Integrated Traffic Management was carried out by the microsimulation model for 15km section on the Seoul Outer Ring Expressway.

우리나라에는 다양한 해상교통기관이 존재한다. 특히 선종마다 각기 다른 면허기관이 존재한다. 상선과 어선간의 통신체계도 다르며, 안전운항관리기관의 특성에 따른 해양사고율도 차이가 크게 나타난 다. 이 논문은 우리나라 연안해상교통의 통항안전관리체제 구축을 위한 기초연구이다.
