  • A subway platform is equipped with screen doors in oder to avoid accidents of passengers, where Area sensors are installed for detecting obstacles in the screen doors. However, there exist frequent operating errors in screen doors due to dusts, sunlight, snow, and bugs. It is required to develope a detection device which reduces errors and elaborates detection function. In this paper, we compared the detection rates of the Area sensor the 3D sensor using CCTV-based image data with installing sensors at the screen door in Munyang station Daegu, where 3D sensor is applied with the space division multiple detection algorithms. It is measured that the detection rate of 3D sensor and Area sensor is approximately 89.61% and 78.88%, respectively. The results confirmed that 3D senor has higher detection rate compared with Area sensor with the rate of 6.87~9.79%, and 3D sensor has benefit in the aspect of installation fee.

  • As the Rope Type Platform Safety Door (RPSD) is now commercially available, the technology of RSPD and the public sentiment towards RPSD are being scrutinized. During the period of RPSD development and trial installation, there has been a need to examine its technical reliability and safety, and its users' emotional attitudes. Though often dichotomized in practice, technological innovation of, and the public sentiment towards RPSD are directly related to continuing and collaborated efforts to enhance public satisfaction with the service. Therefore, based on the analyses of public sentiment towards the RPSD system and the log files of operation, this study evaluates public satisfaction with RPSD during its trial phase at Munyang Station in the Daegu Subway System.

  • The platform safety door is difficult to install in platform because the doors of railway vehicles and existing Passenger Safety doors should be alined. To be able to solve this problem, we propose the use of Rope Type Platform Safe Door (RPSD) which is a vertically retractable platform that is designed to close from top to bottom. This platform has installed safety gate pillars at intervals of 20-40 m which accommodates different types of train regardless of train length, gate opening and location. In this paper, we reviewed the application of existing PSD and RPSD in various train stops in Seoul Gyeongbu Line platform. The results of the review showed that the existing PSD may cause problem in construction, safety and cost efficiency. The use of RPSD however shows that minimal problems will be encountered.
