A Study of Common Ducts Projects for Elimination of Electric Poles on the basis of City Planning

Abstract

Common underground ducts, which were planned to be laid under the park near the west gate of the Shinjuku Station in 1930s, were done as a part of the urban planning project.ln the electric pole removal plan of the Tokyo Postwar Reconstruction Project, the Tokyo metropolitan goverment attempted to include the common underground ducts in the urban planning, but since they were not expressly defined as the facility in the former Urban Planning Act, even after the discussion in the Urban Planning Committee, they could not be a facility which was legally provided. In the present Urban Plannning Act, the common underground ducts are not considerd as a facility of the urban planning, either.However, as far as the newly constructed roads in the D · I · D areas are concerned, if urban plannning are made under the condition that such roads are free from electric poles, the removal of the electric poles would be promoted.
