Abstract
Many people transfer from the automobile to the subway because of increasing in oil price and improvement of mass transit system of Seoul Metropolitan City. But Seoul Metropolitan Subway have brought out passengers discomfort because it is more crowded over the appropriateness because of very high utilization though it is highly technically facilitated. This study deals with the development and simulation study of subway train simulator. We performed the validity simulation study for the simulator for the interval from Sindorim station to Samsung station in Seoul Subway Line 2. We analyzed the simulation results considering crowdedness after we defined the concept of crowdedness. Also we accomplished the analysis of simulation results after simulation under the assumption that the crowdedness is alleviated by controlling the passengers using RFID technology.
