Analysis And Research On Clearing Method Selection For Ningbo Metro

Along with the development of urbanization, the construction of metro has also been hastened all over the country. The common mode of the passenger transit between different subway lines is called "barrier-free transition" mode, which facilitates passengers to change subway lines without exiting the subway station. But this mode has some flaws, among which the biggest is uncertainty of transition stations, resulting in difficulties of profit clearing between different subway lines.This thesis researches the profit clearing methods in subway operation companies all around the world, and analyzes the causes and effects of these methods.On this basis and with relevant references, the thesis analyzes and compares among different algorithms and models in metro clearing. The main analysis and comparison in the Shortest Path Algorithms is on and between Dijkstra Algorithms and Floyd Algorithms; and in the Multi-Paths Option Probability Algorithms, are on and among the Dial Algorithm, the K Shortest Simple Paths Algorithm, and the Traversal Algorithm. The Probability Option Models in analyses and comparisons are Normal Probability Clearing model and Logit model. The thesis also analyzes Path Impedance Setups.In accordance with the above researches and analyses, the thesis develops a clearing method for Ningbo Metro at the perspective of actual situation in Ningbo, and gives examples to be calculated with the method.
