Clustering Analysis of Main Vessel Traffic Flow Observation Lines along Yangtze River

Article Preview

Abstract:

For the reasonable grouping of the 16 vessel traffic flow observation lines along Yangtze River to compare them with each other, essential data of nearly 6 years taken with the mean relative growth rate of traffic flow over the yearly same period set as clustering index, the clustering of the 16 vessel traffic flow observation lines was realized on MATLAB in accordance with the set index based on the basic principle and processes of Agglomerative Hierarchical Clustering Method, which indicated that the observation lines can be divided into 3 classes, and particularly Jiujiang took an exclusive class obviously different from the other two. This work would provide scientific basis of grouping the observation lines in order to reflect shipping economy of the regions where the observation lines are located and to provide reference for management decisions.
