The Research And Estimate On The Utilization About All Channels And Lines Capacity

Railway transportation plays the key role in our national economic development and undertakes important missions in socialist modernization. In these years, the transport capacity can not meet the need of increasing transport demand and our rapid economic development, and it even hider the pace of economic development. In order to insure that transport may adapt the rapid economic development, it is necessary to make a general evaluation of the utilization capacity of whole channels and lines and provide a basis for establishing favorable plan of the existing channels and transport organization reform.Railway transport capacity mainly refers to the district's passing capacity. The district is consist of a number of sections and the restrict section's passing capacity usually determines the section's. Therefore, by researching on the utilization of rational passing capacity of sections, we may directly and effectively learn the utilization of the major channels in our railway network, and it holds the important meaning for the rational plan of railway daily production, combination, dispatching and the long-term planning and implement.By connecting the railway actual situation and researching the relative learners both domestic and abroad, we take the sections as a service system which has a service desk. We take passing trains as customers, and by establishing the section's queuing system, we study the utilization of the section's passing capacity. Combine the time theory of train running with the communication theory of train delayed. Under the premise of ensuring the quality and by calculating the utilization rate of sections and restrict sections, we fix on the stage model of the situation of section capacity. What's more, we may establish the index of the passing capacity of the section and make a comprehensive analysis on the utilization of whole channels and lines. At last, we could put forward the relative advice which could improve the transport capacity of railways.
