Coordination Research On Collection And Distribution System Of Heavy Haul Railway

As a representative of the advanced transportation productivity, heavy haul railway palys a dominant position in mass freight transport. With economic development, demand for mass freight transport begins to accelerate, and brings new challenges to railway heavy haul transport. From the angle of whole system, provided the only railway capacity of transformation can’t improved fundamentally railway transport capacity overloading, only the transportation in each step of matching each other, coordinate with each other, and to meet the market demand. Basing on the research of each step’s ability, this paper analysis of the degree of coordination of heavy haul railway collection and distribution system, finds out the problem of it and to make appropriate measures to improve system’s capacity.Firstly, this paper describes the content and features of collection and distribution system of heavy haul railway, and analysis the formation mechanism of it, then point out that the capacity is the order parameter of system dominated, this has laid a theoretical foundation for full study. Sceondly, the paper from the facilities and equipment coordination, traffic organization coordination and transportation organizations management coordinated describes the coordinate contents of the collection and distribution system, and take Datong-Qinhuangdao collection and distribution system as an example to illustrate the specific performance of three coordinated levels. On the basis of the actual work process of heavy haul transport, this work points out that the ability coordination is the ultimate expression of the collection and distribution system of heavy haul railway, constructes models to calculate subsystem’s ability and the coordination degree of them. Taking Datong-Qinhuangdao railway line collection and distribution system as an example, this paper analysis of the system’s ability coordinate situation at this stage, and puts forward a few optimized initiatives.Considering the fact that the Datong-Qinhuangdao railway is a role model of China’s heavy haul railway,this study will provide new ideas for the development of other overloaded coal transportation channel.
