도심지 지속가능한 도로설계 연구 -동시대 유럽 대도시 사례분석 및 대전 중앙로 설계안을 중심으로- = A Study on Sustainable Street Design in Urban Areas -Focusing on European Case Analysis and Design Proposal for Jungang-ro in Daejeon-

다국어 초록 (Multilingual Abstract)

(Background and Purpose) Greenhouse gas emission caused by human activities in cities is one of the significant issues of global climate change. Besides, concepts of sustainability and sustainable development are widely discussed in many fields of contemporary society. In particular, in many urban areas in Korea, the pedestrian environment is vulnerable due to the vehicle-oriented structure, and a resulting decline in activities and functions has emerged as a problem at the community level. Thus, this paper aims to derive implications from the perspective of spatial design by discussing the specific design plan for sustainable streets in the urban area. (Method) This paper focused on the case analysis of large European cities and the street design plan of Jungang-ro in Daejeon and carried out through the following research methods and processes. First, as a theoretical consideration, the definition of sustainability and the certification system of sustainable buildings were reviewed with a step for advanced research analysis. Second, the contemporary cases for related areas in the European cities were examined. The detailed targets are Massenstrasse in Berlin, Germany; Superilla Peatonal Sant Antoni in Barcelona, Spain; and Distelweg in Amsterdam, the Netherlands. Third, the current status and basic design direction of the Jungang-ro in Daejeon were identified, and sequential development strategies were proposed as a street design plan with its sustainability evaluation. (Results) The sustainability evaluation for the street design plan of the Jungang-ro was discussed based on the opinions of citizens, students, and related experts in the participatory workshops and exhibitions. First, the design plan to create street parks and plazas where visitors can walk and relax is positive for environmental sustainability since it improves the qualitative environment of the target site. Second, if the number of visitors can be expanded from the design proposal and its implementation, it will significantly contribute to the revitalization of commercial areas in the target site. Consequently, economic sustainability can be predicted in terms of allowing visitors to stay longer with the better street structure and accessibility system. Third, it is evaluated that the design proposal promotes social sustainability because the street can be created by reducing social class and spatial conflicts in the local community. (Conclusions) The results of this paper with a design and European case analysis can be noted in terms of the environmental, economic, and social values of sustainability for urban regeneration in the city. Plus, they are possible to be utilized by the local government when the related policies are established in the future. At the same time, applying historical, cultural, and commercial resources in the city with the design simulation process has great academic significance.
