The purpose of this study is to analyze the result and problem of urban design as comparing urban design status following regulation substance by urban design guidelines and it's application. To research of this study, five representative new towns as Bundang in Seongnam, Peyongchon in Anyang, Sanbon in Gunpo, Dunsan in Daejeon, Haeundae in Busan are selected. These cities are commonly developed around the early 1990s in Korea.
This study is consisted of three parts as theoretical study, general case study, and specific case study.
The first part of this study reviews theoretical backgorund on the urban design guidelines, urban design regulations and control elements.
The second part shows the result of comparative analysis between the control substance and the implementation of development in urban design. Main contents of analysis contain boundary of applications, presentational method of regulations, types of regulation, degree of regulatin, type of incentive, exceptional items, similarity of regulation content, and degree of observance for regulation.
Through the above main parts, the problems of urban design can be categorized in four types.
The first type is related on the degree of regulation; it contains shared-wall, roof, building direction, screen wall, screen shutter, and finishing method of wall surface. The second is the regulation standard, which contains floor area ratio, building height, land use, color, parking, and vehicular entrance. The third is management in usage, which contains private signs, open space of building front, open space of building-to-building, pedestrian path, arcade, and vehicular path. The fourth is the implementation of control elements, which contains harmony of existed building, root garden, and fence.
The last part of this study analyzes the inter-relationship between visual objectives of urban design and control elements. Visual characterstics which related on urban design objectives are obtained as continuity, identity, amenity, activity, and publicity. Control elements, which is to support visual characteristics are as below:
·Control element for continuity: shared-wall development, height, building limitation, building line, open space of building front, roof, and arcade
·Control elements for identity: shared-wall development, Building height, Building line, Building direction, and Roof
·Control element for amenity: Open space of building front, shield landscape, public landscape, roof garden, and pedestrian path
·Control element for activity: Building direction, open space of building front, pedestrian path, arcade, and public landscape
·Control element for publicity: Open space of building front, public open space, and public landscape
From the above research and analysis, we can conclude that a control element covers not only a specific single goal but also various others. Based on the survey of actual development status in detail, The supporting effect of a control element for the goal does not appear similarly.
On the center of above mentined control elements, it analyzes the development characteristics in the degree of supporting for the goal.
As a conclusion, this study proposes the basic ways of improvement and suggestions.
