Research on a method for analysis of ship traffic density in harbor water area based on GIS

To some extent, ship traffic density reflects the busy degree and risk degree of the vessel traffic water. Allegedly, the number of ship collision accidents is directly proportional to the quadratic of ship traffic density. Therefore, how to find out the crowded area with high ship traffic density in the port waters and to focus on monitoring ship and to optimize marine traffic flow, which are the urgent problems for the maritime safety administration. Based on analyzing the concept of ship traffic density and distribution of ship traffic density in marine traffic engineering, combining the advantages of spatial analysis in GIS(Geographic Information System) and the application of marine traffic engineering, this paper proposes a high-efficiency computing method of ship traffic density distribution in harbor water area based on GIS developer kit. A prototype experiment system for computing ship traffic density was built and applied to a harbor water area. The result indicates that this proposed method is feasible and efficient.
