【 摘 要 】

The paper deals with the navigational safety of marine traffic. It examines the problem of determining the degree of danger of traffic scheme employed in a certain water area. The most important factor determining the safety of traffic in the water area is frequency of dangerous approaches. Metric of this or that sections of the water area is suggested to be introduced as one of possible variations based on a number and localization of closest points of approach. Specialized Internet resources of free access are used as a source of trajectory data. Your attention is called to traffic modeling technique based on reducing global geographical coordinates to local rectangular and piecewise-linear interpolation. It is shown that despite inaccuracy of initial navigational data and frequency limitation of received information, there is a possibility to create a stable picture(image) of dangerous sections of dangerous sections of water areas. The work is accompanied with the results of the study made on location. Estimation analysis of danger to traffic in the waters of the Inner Sea of Japan has been presented.
