A Space Planning Research under Overhead Expressway in Urban Area

本研究的研究结果如下：(1)高架高速公路下空间的界定。通过整理日本公路公团的法律法规、公用事业标准、园林绿化指南等数据，对城市区域高架高速公路下空间进行界定。(2)设计调查-1：以名古屋若宫大寺公园为例进行设计调查，对名古屋城市高速公路架空下的若宫大寺公园进行摄影、测量、平面及剖面图绘制。研究结果表明，两墩之间的空间改善有两种方式，即利用整体空间和部分空间。(3)设计勘察-2：以大阪阪神高速公路为例进行设计勘察，包括拍摄、测量、绘制阪神高速公路架空空间平面及剖面图。调查结果指出了公园中部分空间因雕塑、家具等元素而导致景观整体平衡松动的问题。(4)景观改善建议：利用本研究的评价方法，展示了阪神高速公路架空空间的景观改善形象。

The research results of this study are follows.(1)Definition of the space under overhead expresswayThe data of law regulations, utility standards and landscaping guidelines from Japan Highway Public Corporation are arranged to define the space under overhead expressway in urban area.(2)Design survey-1 : Case study of Wakamiya Ohdori Park, NagoyaThe design survey was operated which includes photographing, measuring, and making plan and sectional-perspective drawings of Wakamiya Ohdori Park as the space under overhead nagoya Urban Expressway.The result was shown that there are 2 types of space improvements such as using whole space between two piers and using in part of space.(3)Design survey-2 : Case study of Hanshin Expressway, OsakaThe design survey was operated which includes photographing, measuring, and making plan and sectional-perspective drawings of the space under overhead Hanshin Expressway.The results of survey pointed out the problems that some spaces in parks loose the scenic total balance because of their elements such as sculptures and furnitures.(4)Proposal of landscape improvementThe images of landscape improvements of the space under overhead Hanshin Expressway were shown by the evaluation methods from this study.
