A Study of the Integrated System of Visual Calculation for the Throat Capacity of Railway Stations

Based on the analysis and comparison of the calculation methods home and abroad on the operation capacity of railway station throat, this paper puts forward the frame and function designs of the integrated system of visual calculation for the throat capacity of railway stations, models the layout and configuration of the station throat and operation processes. And the network optimization model of throat operation arrangement and the compound staged decision model of throat operation capacity are also presented. The above models and algorithms in combination with computer and graphics technologies are integrated to create an operation simulation system, which can realize such functions as operation data gathering, capacity assessment and optimization, and. in pictorial forms. The practical simulation justifies that the results are reasonable and the system is suitable for the throat capacity evaluation of railway stations.
