교통약자를 배려한 안전스텝 개발에 관한 연구

In the platform of the urban transit system, a certain gap is inevitably made between the subway vehicle and the platform, and the gap gets wider in the curved area of the platform. This gap contributes to decrease passengers' safety. In this paper, we presents development process for safety step, trends of safety step, development plan, technical description and etc. In this study, we has considered safe operation of the subway vehicle when safety step are operated closely related to the doors, and explored the possibilities to put it into practical use.
