초록

The aimof this research is to develop an expanded environmental assessment method to select the environmentally friendly road route by appling the environmentweighted value bywork types for both flat route and vertical road route. The previous researches on environmental impact assessment for the planning and construction of road routes consider the flat-route only. There has been no study for comparative evaluation in degree of environmental damage impact between flat route and vertical road route, and thus actual environmental evaluation was not possible. To overcome the limitation of the previous environment friendliness assessment techniques in flat road route,environment weighted value by work types was developed and was applied for the assessment of environmental factors for vertical road route. To calculate the environmentweights bywork type, representingwork types related to the road project were determined, and impact factors by work types and environmental assessment items, were analyzed, and then, the degree of importance by work types were suggested on based of the analysis result. To verify the suggested importance level and to induce the its weight, survey research on degree of the positive and negative impact on the environment bywork typeswere carried out and road expertswere participated in, Eight items for environmental impact assessment bywork types in road projectswas included in the questionnaire. With quantification process of the survey results by items and work types, and through calculating the average percentage of the assessment items, and environment impact scores of road routes by work type were estimated. With the estimated environment impact scores by work types, it was to assess the environment friendliness of the vertical road route. In order to prove the validity of the proposed expanded methods, three road construction projects were selected as test beds and the environment impact scores of 3 road routes were assessed with the proposed method. The proposed method consider three alternatives such as avoidance, mitigation, replacement, to improve environment friendliness and the results showed that the degree of environment friendliness was increased for the test bed routes with more road structural works, such as bridge and tunnel, etc. These results proves that, although construction of more road structures in the road in mountainous area may result in higher project cost, the degree of environment friendliness was improved greatly and thus it is more environmentally and economically favorable choice in overall.
