Development of Web-based Flooding Evaluation System for Safe Operation of Bi-Modal Tram

초록

The Korea Railroad Research Institute (KRRI), Korea has been developing next generation tram system, which is called the Bi-modal tram because it can be operated automatically with 2 sensor tracking system on the route or manually in emergency situation. Since this Bi-modal tram system detects the sensors installed on the tram route for its automatic operation, the safety of the Bi-modal tram system needs to be secured in case of unexpected disastrous simulation such as torrential rainfall. Thus the Web GIS-based Bi-modal tram disaster management system (BTDMS) was developed in this study for these ends. This system has abilities in retrieving the real-time weather forecast from the Korean Meteorological Administration (KMA) for flooding and forecasting with the Web programming. The BTDMS system with local topography and sewer system information first simulates the rainfall-runoff at all subcatchments defined in the BTDMS, and then simulate flow hydraulics within the sewer system for possible urban flash flooding for a certain period time at subcatchments within the Bi-modal tram route and surrounding catchments. The Bi-modal tram operation can be rescheduled or re-directed to other safe routes in real-time using the simulated result of this system. The Web GIS-based BTDMS system can be easily applied to other Bi-modal tram route and utilized for other transport facilities.
