The Research On Y Channel Traffic Transit Capasity

The Research on the channel traffic transit capacity is an.important issue of supporting the decision of port construction and operational management. The port channel traffic transit capacity directly affects the role of the whole port transit capacity. Therefore, to decide the calculation and analyses method of the channel traffic transit capacity is of great significance to increase the investment profit of channel project and ensure the full play of port loading and unloading efficiency. However, the port vessel navigation operating system is a system of many random factors and the random service of dynamic linking complexity, which results in the great difficulties of the channel traffic transit capacity. Y channel is the more common channel, which is used in many ports and waterways. The research on the transit capacity of Y channel, especially the transit capacity of intersection is of practical significance to make reasonable use of Y channel and ensure the ship safety and efficiency.The paper makes analyses of the main factors of affecting channel traffic transit capacity based on lots of literature and reference of the predecessors and explains the vessel traffic flow overview of Y channel by using roads, vehicles, fairways and vessels. The paper also introduces the calculation method of highway ring road intersection transit capacity to introduce the concept of intertwined transit capacity and acceptable gap theory, defines the related concept of channel and applies them into channel on the basis of intertwined transit capacity theory model in order to establish the theory model of channel intertwined. Finally, the paper makes analyses of the possible problems existing in the model.The paper is of certain scientific and reasonable significance as well as practical significance of the research on the channel traffic transit capacity, which also has its referential significance of transit fairway safety management work of the port passing fairway management and marine department.
