  • The safety management of a road network comprises four basic inter-related components:identification of sites(black spot) requiring safety investigation, diagnosis of safety problems, selection of feasible treatments for potential treatment candidates, and prioritization of treatments given limited budgets(Persaud, 2001). Identification process of selecting black spot is very important for efficient investigation of sites. In this study, the accident prediction model for EB method was developed by using accident data and geometric conditions of black spots selected from four-leg signalized intersections in In-cheon City for three years (2004-2006). In addition, by comparing the rank nomination technique using EB method to that by using accident counts, we managed to show the problems which the existing method have and the necessity for developing rational prediction model. As a result, in terms of total number of accidents, both the counts predicted by existing non-linear regression model and that by EB method have high good of fitness, but EB method, considering both the accident counts by sites and total number of accident, has better good of fitness than non-linear poison model. According to the result of the comparison of ranks nominated for treatment between two methods, the rank for treatment of almost sites does not change but SeoHae intersection and a few other intersections have significant changes in their rank. This shows that, with the technique proposed in the study, the RTM problem caused by using real accident counts can be overcome.

  • It is crucial In decision making to select a project delivery system (PDS) adjusted accordingly to the project characteristics. Furthermore, selecting a tendering system is the kernel in the process of selecting PDS. In October 2007, the Ministry of Finance and the Economy of Korea launched two new project delivery systems, "Best Value Contract (Design-Bid-Build)" and "Bridging Contracts (Design-Build)" by revising enforcement ordinances of "Act on Contracts to Which the State is a Party" to provoke the tendering systems. In order to support the proposed purpose, this research developed a selection model for suitable tendering system, which helps a public owner select a tendering system appropriate to the project characteristics. First, the framework of the model was set throughout analyzing previous researches and interviewing relevant experts. Additionally, by analyzing the survey result from 265 experts engaged in architectural and civil engineering business, the relative weights of the selection factors and the effectiveness values of the alternatives were suggested as the quantitative evaluation references. Finally, the practical guideline was suggested to apply this model to three public projects scheduled to be delivered. The result of applying the model to three case projects showed that further researches were needed to make the selection process logical and to suggest the standard weights and effectiveness values according to project type.

  • Project delivery systems determine the relationship, responsibility, authority and the scope of works of those involved in project, hence, optimum project delivery system should be selected to so that construction project would be executed successfully, Until now, the traditional design-bid-build mainly has been used for public projects, but the government is making efforts actively to introduce other methods such as design-build, alternative bidding by its policy. However, delivery systems should be determined through considering physical projects characteristics, owner's goals, external factors, etc, rather than government' policy. Therefore, the purpose of this research is to propose objective delivery system selection criteria and delivery system selection model, which help owners to select the suitable delivery system through quantitative and reasonable manner.

  • Turnkey and alternative-design contracts was introduced operation in the country from january 2004 to February 2010. this was introduced operation. The selecting method of contractor for turnkey projects has being operated by an open forum type that consists of technical committee and appraisal committee in an integrated design approach deliberations. But to improve the operation of the problems, the government is operating design review committee consisting of the central, local and special design advisory committee in march 2010. But this system has also been suggested as still problems, too many contracts by large companies, increasing of design cost and excessive competition. This study is intended to contribute that turnkey and alternative-design contracts can be well operated in domestic construction markets. In this paper suggests some improvement methods and operational problems caused from application of an open forum type for selecting contractor of turnkey project.

  • 기후변화 대응은 온실가스 배출의 감축 및 흡수원을 확대하는 완화(mitigation)와 기후변화로 인한 영향과 취약성을 평가하여 피해를 최소화하는 적응(adaptation)이 상호 균형을 이루어야 한다. 지금까지 우리나라를 포함한 국제사회는 대부분 완화를 위해 노력해 왔지만 최근에 들어 완화만으로는 기후변화의 영향을 회피하기 어렵다는 사실이 인식되면서 적응 연구가 다양하게 이루어지고 있다. 이러한 상황 가운데 적응 계획의 실현화를 위해서 기후변화의 불확실성을 고려한 의사 결정에 관한 연구가 반드시 뒷받침 되어야 한다. 기존의 일반적인 의사결정은 다양한 미래 시나리오들 하에 가장 높은 효용을 가져오는 최적(Optimal)의 대안을 채택하는 고전적 결정분석(Classical Decision Analysis)의 프레임을 사용하였다. 그러나 기후변화로 인해 미래 기후 예측 시나리오의 불확실성이 증대되면서 최근에는 최적의 대안을 선정하는 것에 대한 의문이 제기되며 새로운 기법에 대한 연구가 이루어지고 있다. 본 연구는 기후변화의 불확실성을 고려하기 위한 새로운 의사결정 기법인 로버스트 의사결정(Robust Decision Making, RDM)을 실제유역의 적용을 통해 제안하고자 한다. 로버스트 의사결정은 RAND에서 개발한 것으로 최적의 대안을 채택하는 것 대신 모든 가능한 시나리오 가운데 가장 안정적인 전략을 채택한다는 것에서 기존의 의사결정 체계와 차이가 있다. 연구의 적용은 안동-임하댐 유역을 대상으로 온실 가스 배출 시나리오 A1B, A2, B1시나리오에 대해 15개의 GCMs에서 산출된 기후자료를 기반으로 기후변화의 시나리오를 작성하였으며, 다양한 측면의 대안을 설정하여 용수공급량을 평가하였다. 연구의 결과로 산정될 각 대안 별 안정적인 정도와 취약한 시나리오에 대한 정보는 기후변화의 불확실성을 전제한 의사결정을 할 때 로버스트 의사결정이 갖는 장점이 될 수 있다.
