공공시설 중 도로계획의 경우 건설과정 및 건설 후의 소음 및 오염 등의 환경 사회적 비용 및 주행성 안전성 등 요소의 평가 등을 수량화가 어려운 대표적 비용으로 들 수 있는데 본 연구에서는 이러한 수량화가 어려운 비용 효과들을 포함하여 고려한 도로노선계획결과를 정보계측기법과 지리정보시스템을 이용하여 '정보량'이라는 통일된 단위로 표현하고, 기존 시설물과의 관계로부터의 '정보편익' 개념으로 평가하였다. 정보계측기법은 인간은 언어를 통하여 모든 사물을 정보로 표현하므로 '정보'라는 통일 된 단위를 사용하여 모호한 가치를 평가해 보고자 하는 방법이며, 따라서 공공시설의 계획과정에서 최적해를 찾기 위한 비용, 편익 및 환경 사회적 요소 등의 정량화되기 어려운 가치를 평가하는데도 사용될 수 있을 것이다. 정보계측기법과 지리정보시스템을 이용하여 도로건설시 발생하는 비용과 직접효과를 고려하기 위하여 시설정보계측모형을 개발하였으며, 도로 주변 시설간의 편익을 고려하기 위하여 시설정보편익모형을 구성하였다. 개발된 모형을 실제 도로계획 사례에 적용한 결과 비용과 직접효과만을 고려한 시설정보계측모형에서는 기존의 도로설계와 유사한 결과가 도출되었으며, 시설정보편익모형에서는 기존의 도로계획 평가에서 고려할 수 없었던 요소들에 대한 고려가 가능하였다.

Better understanding of in-situ mechanical behavior of pavement foundations is very important to predict long-term effects on the system performance of transport infrastructure. For this purpose resilient stiffness characterization of geomaterials is needed to properly adopt such mechanistic analysis under both traffic and environmental loadings. In this paper in-situ monitoring data from KHC test road were used to analyze the non-linear response using finite element method for a selected constitutive model of foundation geomaterials, and the results were compared with the field data.

This research has proposed a quantitative environmental assessment method of road routes based on the various policies and literature, and applied such proposal to the planned road routes to evaluate the environment-friendly road routes. Accordingly, the case sections per each region of Joong-bu, Gang-won, and Nam-bu were selected to execute the proposed environmental assessment method. Consequently, it has been confirmed that the distribution of environmental score of the subject region of each case section varied. In particular, for the Gang-won region, the high scores took up the most. Also, to indicate the degree of environment per each section, a route which minimizes the environmental effects per subject region was created to analyze the environmental degree per each section. As a result, the section in the region with the highest environmental sensitivity, in other words the Gang-won region with many high scores, had the lowest environmental degree.

Abandoned roads, abandoned expressways included, cause a lot of problems such as contamination and environmental damages to underground water, fragmentation of wildlife habitats yet they are not appropriately maintained or managed because of jurisdictional conflicts and, often more importantly, insufficient budget of governments. The restoration of abandoned roads is known to benefit society and its constituents by providing better environment and higher living standards but the monetary value of the benefit is hard to measure because of non-marketability of the good that the restoration brings about. In this case, the contingent valuation method(CVM) is most powerful in evaluating non-marketable value of goods and hence it is used widely. We also used the CVM to value the benefit of restoration of abandoned expressways to find out: about 40% of total households are willing to contribute positive amount for restoration; better awareness of environmental issues leads to higher willingness-to-pay.

This study was conducted to investigate the effects of road on bird community by line transect census method from May 2000 to January 2001 in Mt. Geumsan, Namhae-Gun, Kyeongsangnam-do. Canopy layer was more developed in forest area than road area. Understory vegetation of road area was more developed than forest area. Twenty six and twenty three bird species were observed in road and forest area, respectively, White's thrush and ashy minivet were observed just only in forest area, and Siberian blue robin, blue-and-white flycatcher and gold crest were in road area. The birds being to bush nesting and foraging guilds in road area were more than forest area. It is known that the road construction was negatively affected on bird community. However, road construction would be not so negative on bird community according to the results of thie study. It would be needed the maintenance of upper canopy layer and understory vegetation to reduce negative effect of road on bird communities in forest area.

1968년 경인고속도로를 시작으로 국내 도로환경이 변화하면서 교통소음이 주거환경에 문제로 제기되었으며, 80년대부터 시작된 포장재질의 콘크리트화 추세는 교통소음의 증가요인이 되었고, 신도시 고속도로 및 도시외곽 순환도로 등의 확충 사업은 주거환경 내에서도 교통소음을 발생시키고 있다. 이와 같이 도로교통소음은 주거환경의 쾌적성을 침해하는 가장 큰 요인으로 1993년 국내 환경오염 피해진정 건수중 소음.진동의 민원이 약 44%로 가장 높게 나타나고 있는 실정이며. 문제가 교통소음의 발생원은 자동차 발생소음(power level)은 각 음원별 소음특성을 검토 하는 것이 중요하나 소음의 평가방법에 대한 연구는 국내.외에서 각 음원별 특성을 포함한 연구로 1970년대 이후 급속히 전개되어 왔으나, 최근 도로변 건물의 고층화 현상은 방음(전파경로)대책 수립에 한계를 나타내고 있는 실정이다. 이와 같은 문제 점을 해결하기 위해서는 그동안 체계적인 연구가 이루어지지 않은 노면(포장)형태에 따른 자동차 주행소음의 특성에 관한 연구가 이루어져야 할 것으로 판단한다.

Generally, traffic accidents can be influenced by variables driving conditions including geometric, roadside design, and traffic conditions. Under the circumstance, homogeneous roadway segments were firstly identified using typical geometric variables obtained from field data collections in this study. These field data collections were conducted at highways located in several areas having various regional conditions for examples, outside metropolitan city; level and rolling rural areas. Due to many zero cells in crash database, a Zero Inflated Poisson model was used to develop crash prediction model to overestimated results in this study. It was found that EXPO, radius, grade, guardrail, mountainous terrain, crosswalk and bus-stop have statistically significant influence on vehicle to vehicle crashes at rural multi-lane roadway segments.
