Location of freight hub based on cluster analysis of GPS points of freight cars
According to the distribution of GPS points of freight cars,this paper establishes a convergence model of cluster number of GPS points of freight cars by means of cluster analysis and based on the economic benefit principle of covering the most GPS points and least cluster centers,which can preliminarily judge the suitable position for building freight hubs and provide a theoretical method based on big data for the scientific and rational layout of freight hubs.Taking Zhaoqing City,Guangdong Province as an example,the preliminary location of freight hub is obtained,and the results are consistent with the current planning and policies,which verifies the rationality and reliability of the model.
