Abstract
The Korea Railroad Research Institute (KRRI) has developed a bimodal tram and advanced bus rapid transit (BRT) system which is an optimized public transit system created by mixing the railway’s punctual operation and the bus’ easy and convenient access. The bimodal tram system provides mass-transportation service with an eco-friendly and human-centered approach. Natural disasters have been increasing worldwide in recent years, including floods, snow, and typhoons disasters. Flooding is the most frequent natural disaster in many countries and is increasingly a concern with climate change; it seriously affects people’s lives and productivity, causing considerable economic loss and significant damage. Enhanced conventional disaster management systems are needed to support comprehensive actions to secure safety and convenience. The objective of this study is to develop a prototype version of a Web GIS-based bimodal tram disaster management system (BTDMS) using the Storm Water Management Model (SWMM) 5.0 to enhance on-time operation and safety of the bimodal tram system. The BTDMS was tested at the bimodal tram test railroad by simulating probable maximum flood (PMF) and snow melting for forecasting flooding and snow covered roads. This result could provide the basis for plans to protect against flooding disasters and snow covered roads in operating the bimodal tram system. The BTDMS will be used to assess and predict weather impacts on roadway conditions and operations and thus has the potential to influence economic growth. The methodology presented in this paper makes it possible to manage impacts of flooding and snowfall on urban transportation and enhance operation of the bimodal tram system. Such a methodology based on modeling could be created for most metropolitan areas in Korea and in many other countries.
Highlights
Korea has a small land area (100,210 km2) and one of the highest population densities in the world
For fast and accurate simulation of urban flash flooding to secure the safety of passengers on the bimodal tram, a Web GIS-based bimodal trams disaster management system (BTDMS) was developed in this study
Functionalities are not needed for the Web GIS-based BTDMS, the Storm Water Management Model (SWMM) interface was modified for simulation of urban flash flooding
Summary
Korea has a small land area (100,210 km2) and one of the highest population densities in the world. The population concentration in Korea has become a serious social problem and had led to an explosive increase in demands for transportation [1]. Many attempts have been made to overcome limitations in existing transportation in other countries [3]. The Bus Rapid Transit (BRT) system has advantages over others in providing flexibility as well as speed with low cost. The BRT system has been operating in Europe and the United States as well as many other countries because of its lower construction cost compared with other transportation [4]
