보행전용 고가도로의 경관특성 파악을 위해, 시각적 선호도 및 심리적 변수와 관계를 파악하였으며 경관파악모델을 토대로 경관변화 특성을 분석함으로써 이를 통해 도시 내에서 보행전용 고가도로 조성 시 경관 측면에서 고려되어야 할 요인을 분석하여 시사점 도출을 목적으로 하였다. 분석 결과, 자연요소가 대부분의 경관을 차지하고 있는 경우 선호도가 높게 나타나, 자연요소를 포함한 경관이 주요함을 알 수 있었다. 또한, 분석된 특이성·심미성·개방성·친숙성 등 4개 인자군 중 특이성이 선호 도에 가장 큰 영향력을 미치고 있어, 고가보행로라는 대상지의 특성 때문에 이러한 결과가 나타났음 을 파악할 수 있었다. 또한, 경관요소의 관계성을 분석한 결과 고가 내 식재된 수목이 주대상으로 분석된 사진에서 선호도가 높게 나타났으나, 주대상이 건축물로 분석된 경우 선호도가 낮게 나타나 도심의 고가보행로에서 자연요소가 중요한 경관 요소임을 파악할 수 있었다. 본 연구는 보행전용 고가도로 경관특성을 선호도, 경관이미지뿐만 아니라 경관요소의 관계성을 파악할 수 있는 경관파 악모델을 활용함으로써 조성 시 고려되어야 하는 경관 요소에 대한 기초 데이터로서 의미가 있다.

The purpose of this research is to evaluate Seoullo 7017 based on Universal Design (UD) principles and guidelines. To derive UD principles applicable to the site context, we used the 2017 Seoul Universal Design Guideline and assessment index provided by the Universal Design Research Center and established 11 evaluation criteria. With respect to research methods, a literature review and on-site field survey were applied, through which we derived UD principles and evaluation criteria to identify UD problems. The 11 evaluation criteria consist of pedestrian space, facilities, access, main entrance, parking lots, trails, restrooms, convenience facilities, information facilities, rest areas, and playgrounds, and these were associated with UD principles for evaluation. As a result, the main entrance had the highest UD score, while parking lots had the lowest in terms of equity, safety, simplicity, and accessibility. Restrooms received a lower UD score because of poor conditions of security and alert systems. Rest areas were found to be uncomfortable for disabled people. With respect to the internal trails, we found the lack of braille block and irregular placement of planting pots made blind people uncomfortable when walking. In terms of UD principles, flexibility received the highest score, followed by amenity, equity, simplicity, tolerance, accessibility, and safety. Flexibility received the highest score, owing to the provision of proper information about convenience facilities and trails, while safety received the lowest, based on poor access to parking lots, inadequate paving materials and colors, and a lack of 24-hour security systems. We hope this research contributes to improving the universal design, so that people are not discriminated against in the use of the park in terms of age, sex, or physical disability. We expect the study to help facilitate empirical studies to verify UD principles and provide improved quality of UD for Seoullo 7017.

This study was conducted to investigate attention restoration effects provided by Seoullo 7017, an elevated public skygarden newly transformed from a 40-year-old overpass as a part of an urban revitalization project. In October 2017, a questionnaire survey utilizing Perceived Restorativeness Scale (PRS) and Zuckerman Inventory of Personal Reaction Scale (ZIPERS) was conducted among employees visiting Seoullo 7017 and 133 valid responses were collected. From a series of factor analyses of PRS and ZIPERS items, four PRS factors were derived from 16 PRS items and named as “Diversion”, “Boring”, “Coherence” and “Compatibility”; and two ZIPERS factors were extracted from twelve ZIPERS items, namely “Positive impacts” and “Negative impacts”. Significant differences in restoration effects and psychological stress were found according to frequency of visits, accessibility, and whether or not Seoullo 7017 was seen from offices. In conclusion, the newly created Seoullo 7017 was found to have healing effects, such as psychological stability and relief from stress, on employees who could easily access the garden.

Seoullo7017, an elevated linear park, was created to redevelop obsolete road infrastructure as public space, which provides unique landscapes. This study was aimed to evaluate and suggest proper planting design for improving psychological benefits in Seoullo7017. Field survey and simulation experiment were carried out to investigate the user’s perception on the landscapes. Many users had negative feelings of the present landscapes in Seoullo7017, due to concrete pavement and simple planting design using big concrete pots. Landscape simulation experiment showed this perception could change depending on planting design. In especial, herb species played an important role in improving the quality of landscape in a linear park and providing positive feelings such as refreshment, warmth and naturalness. This study suggested that planting design in a linear space needs to be focused rather on the planting style and species than the volume of greens.
