摘要：如今人们开始日益关注和重视步行，且致力于提升步行的公共空间及其质量。然而，步行空间信息的缺乏导致难以将步行空间纳入空间规划范畴。在这项研究中，作者调查了东京市中心步行空间的分布特征，并研究了如何结合建筑、公共交通和城市更新项目，来创建步行空间。首先，对步行空间分布的分析表明，东京市中心的道路面积平均占21.8％，由18.8％的道路和3.0％的人行道组成，步行空间积聚在中心和次中心区域，同时也在城市更新项目区域，具有较高的建筑密度。其次，商业区的人行道在建设的过程中，更多地考虑了建筑密度和与行人交通流量相关的乘客数量。另一方面，住宅和工业区的人行道是通过建设道路而建造的，与商业区中的人行道建设相比，对建筑密度和公共交通的考虑较少。在中等建筑密度的住宅区，人行道的优先级低于车行道空间。第三，城市更新项目未必需要更多地考虑行人，所有其他条件都是平等的。城市更新重建项目对人行道比例的影响范围有限。

Abstract: Interest in and the importance of walkability have begun to grow, and efforts are now being made to support pedestrians and the quality of public spaces. Lack of information on pedestrian space, however, makes it difficult to incorporate walkable space into spatial planning. In this study, the distributional characteristics of pedestrian spaces in central Tokyo were investigated, and how pedestrian space has been created and related to building, public transportation, and urban renewal projects were examined. First, analyses of the pedestrian space distribution suggest that road area accounts for 21.8% on average in central Tokyo; this is composed of 18.8% roadway and 3.0% walkway, that pedestrian spaces are accumulated in central and sub-central areas, which have high building density, and in urban renewal projects areas. Second, walkways in the commercial area have been built with more consideration for building density and the number of passengers that are related to pedestrian traffic flow. On the other hand, walkways in the residential and industrial area have been built by constructions of roadway with less consideration for building density and public transportation compared to commercial areas. There was less priority to walkway than spaces for automobiles in residential areas with medium building density. Third, urban renewal projects did not necessarily give more consideration for pedestrians, all other things being equal. The effect of redevelopment projects on walkway ratio was limited in their scope.
