Research And Development Of Computational System For Throat Traffic Capacity Of Railway Station

Calculation of the traffic capacity is one of the most important steps in railway station design. As the inevitable area that trains pass through, arrangement of throat is definitively affect the traffic capacity. Therefore, calculation of throat capacity is significant affect checkout of railway station design and comparison of design scheme. At present, researches internal of throat capacity basically focus on the phase of train dispatch. The mainly research is how to arrange the task route reasonably by the maximum limit use traffic capacity. But these research methods and achievements have not introduced in the station design. The station design finally is must serve the railway transportation and organization. So if we can consider the question of traffic capacity using fully in the design stage, and consider task arrangement reasonable, will be more advantageous to the next schedule job, also will be able to cause the design result to conform to the actual situation. This paper analyses the throat traffic capacity computation theory to research optimization method of task arrangement as well as the way search algorithm in throat thoroughly. So as to establish a computing system that suitable for calculation of throat traffic capacity in the stage of the station design.This paper first introduces the computing methods of throat traffic capacity and optimization methods of task arrangement, and carries on the analysis comparison to optimization methods.Secondly, carries on the analysis to the computational method of throat traffic capacity, conducts the research, the supplement and the consummation to the optimization algorithm of task arrangement, analyzes and studies the search route algorithm, propose the throat traffic capacity computing system principle of design.Thirdly, the theory and the algorithm summarizes which using front have developed the computing system realization procedure of throat traffic capacity, to the system demand, the realization function as well as the system design thought carries on the analysis, carries on the design to the system structure and the interface, and summarizes the development kit and the development environment.Fourthly, carries on the practical application to the system through the example, introduce the system use procedure in detail, and carries on the analysis to computed result of the example, discusses the important parameter value.Finally, the paper has carried on the summary to the computing system research of throat traffic capacity, and bases on questions and insufficiencies which meets on the research, propose some forecasts to the theory of computation, realization method, the direction of next step studied as well as the aspect that system should be consummated.
