Abstract
Since the Law for Promoting Easily Accessible Public Transportation Infrastructure for the Aged and the Disabled was enacted to ensure the convenience and safety of elderly and handicapped people travelling with the use of public transportation, a short time ago, Partial-Height Platform Screen Doors designed to ensure the safety of passengers has drawn attention. As Partial-Height Platform Screen Doors become widely used, safety is required to be ensured under different installation conditions. Among them, ensuring the safety at curving points on the platform is one of the major challenges. Gap filler is used for ensuring the safety of passengers at those points by filling the gap between trains and the edge of the platform. Before the development of this equipment, equipment was operated manually by station staff. Thanks to the development of this equipment, automatic control operation without operation by station staff has become available. As Gap Filler is installed within the structure gauge, the development includes not only safe motion of the equipment but also enhancement of the reliability of the system. This paper provides an outline of Gap Filler, required specifications and its reliability and safety. This paper also introduces the system used in conjunction with Partial-Height Platform Screen Door and refers to the latest trend.
