Automatic detection of collision danger is one of the most important functions required for marine traffic systems equipped with radars and computers. DCPA plus TCPA criterion has been used for the detection as well as shipborne collision avoidance systems and is useful in waters except congested ones. However, the blinkings of radar targets on CRT which indicate collision dangers to a control officer are apt to be too many in congested waters. Improved methods are proposed here which is based on the results of the study on the effective domain. One is "modified DCPA plus TCPA method" which reduces the number of blinkings to 1/2〜1/20 of that by usual DCPA-TCPA method for the same safety leuel. Another is the "bumper around ship" method which is being examined at Nakhotka Marine Traffic System. Data for DCPA and TCPA as well as for the bumper are suggested.
