Research On The Key Technology Of City Rail Transit Network Operation Organization

With the rapid development of urban railway transit today, new railway line to the new line construction, many big cities railway transit network have begun to take shape and network characteristics are also increasingly apparent. In the present situation of railway transit network, the complexity of the urban railway transit network structure continued to improve, the difficulty of the operation and management of railway transit increasing, therefore the technology and method of operation organization of city railway transit management are need to be research to improve the operation efficiency.On the basis of existing research, and reference to previous research results, integrating use of city rail transit operations, mathematical modeling, optimization theory, engineering system and other related theories, this paper has conducted thorough research on the key technologies and party organization operation of city rail transit network law. The paper introduces the complex form of network lines and passenger flow with time and space; Based on the existing complex routing forms were established on the train routing optimization model; Study about network conditions scheme and the optimization model of vehicle running speed combination; at last based on a certain cross road, combined with the change of passenger flow and conditions of express and local train operation, in-depth analysis of the research on coordination optimization and related algorithm running lines on network conditions, and an simple example is given.
