본 연구의 목적은 언론분석을 통해 해양선박사고 대응을 위한 기술개발 수요를 도출하는 데 있다. 현재까지 해양분야의 기술개발 수요는 주로 Bottom Up 방식을 활용해 연구개발현장에서 필요한 기술수요를 도출하고, 이를 기반으로 기술개발이 이루어지는 방식이 적용되어 왔다. 그러나 이와 같은 방식에 의해 개발된 기술들은 실제 해양선박사고가 발생하였을 때, 현장에서 적용되기 어렵다는 문제가 존재하였다.

PURPOSES : Traffic congestions which occur in the intersections of arterials lead to mobility and environment problem, and then traffic agencies and engineers have been struggling for mitigating congestions with greenhouse gas emissions. As an alternative of solving theses problems, this study is to introduce a low-cost and high-effectiveness countermeasure as unconventional intersections which are successfully in operation in U.S.. The main feature of unconventional intersections is to reroute turning movement on an approach to other approach, which consequently more green time is available for the progression of through traffic. Due to improved progression, this unique geometric design contributes to reduce delays with greenhouse gas emission and provides a viable alternative to interchanges. This study is to evaluate the potential operation and environment benefits of unconventional intersections. METHODS: This study used the VISSIM model with Synchro and EnViVer. Synchro is to optimize signal phases and EnViVer model to estimate the amount of greenhouse gas emissions by each condition. RESULTS : The result shows that unconventional intersections lead to increase the capacity and to reduce greenhouse gas emissions, compared to existing intersections. CONCLUSIONS: Unconventional intersections have the ability to positively impact operations and environments as a low-cost and higheffectiveness countermeasure

PURPOSES : This study presents a specific methodology for air dispersion analysis of urban areas methodology in accordance with urban planning and transport policy. METHODS: This study performed three alternatives including development density and public transit applying integrated urban model for the Delft city on Netherlands. Based on this result, the two types of air pollutant emissions(PM10, NOx) were calculated and analyzed the emission dispersion on that City. RESULTS: As a result, the quality of air near the City is better than that of current conditions showed that approximately from 2.1 to 7.9% according to alternatives. CONCLUSIONS: Air quality assessment in urban areas can be reasonably performed by applying a methodology when urban development and transport policy are considered.
