京都•都心部の無接道敷地における接道状況と敷地形状から見た変容とその要因: 京都市明細図にみる居住空間の再現とその変容(その2)

摘要

本稿では伝統的な路地景観が残る京都•都心地区の無接道敷地における昭和26年時から平成22年時までの接道状況の変化および敷地形状の変化を考察してきたが、これから下記の点が明らかとなった。①無接道敷地の接道状況の変化では、無接道敷地が平成22年時までに概ね半減していることがわかった。「無接道敷地ではなくなった」路地空間における敷地形状の変化をみると、当該敷地が周辺敷地に取り込まれ敷地が大型化し、接道規定を満たした例であり、多くは表敷地へ統合であった。%In Kyoto downtown district, the 'Road Contact Failure' of the traditional Alley space is considered as a big hazard, regarding the disaster prevention and evacuation. This paper has focused on the transformation process of the Road Contact Failure area, by clarifying the changes in the road contact conditions, the site form as well as the relationship between each other. Further discussion is given on the challenges point towards the rescue techniques applied in Road Contact Failure area by revealing the factor which caused the changes in the road contact condition and the site form, not only in a comprehensive city level, but also in a specific site level. To conclude, it is found that there is a mutual relation between the road contact conditions in the target site and the ones in the peripheral site. Moreover, regarding the application of the deregulation, it was pointed out that the existing road contact conditions in both the target site and the peripheral site should be considered.
