Abstract

The invention discloses a traffic comprehensive competitiveness analysis method and system based on three-dimensional coordinates of global cities. Matrix A is input into the preset three-dimensional traffic coordinate system of global cities; matrix Q is standardized to obtain matrix T; information entropy E is obtained by calculating the information entropy of matrix T coordinates; according to the coordinate information and information of matrix Q Entropy E, to the value of the element in the weight matrix W; according to the value of the element in the matrix Q and the weight matrix W, the comprehensive competitiveness of the urban traffic corresponding to the element is calculated, and the comprehensive competitiveness of the traffic of various cities can be analyzed, so as to realize In order to calculate the comprehensive competitiveness of transportation for various cities through a simple and convenient calculation method.

Description

technical field [0001] The invention relates to the field of traffic and transportation engineering, in particular to a method and system for analyzing comprehensive traffic competitiveness based on three-dimensional coordinates of global cities. Background technique [0002] All cities in the world, regardless of their size, economic level, industrial characteristics or hinterland pattern, have a certain internal relationship and comparability. The current ranking methods for global cities mainly include: the roster of world-class cities issued by the Globalization and World Cities Study Group and Network (GaWC for short), and the global city indicators issued by the US Kearney Company. (GCI / GIO) and the Global City Power Index (GPCI) released by the Japan Mori Memorial Foundation Urban Strategy Research Institute, etc. The list of world-class cities studies the distribution of global high-end production and service companies in five industries including finance, accountin...
