The Vessel Traffic Services, abbreviated as VTS, is for the safety and efficiency of vessel traffic. It is often understood as "Vessel Traffic Management System, VTMS". Following to the first survey in 1977 and the second in 1982 on VTSs in the world, the third survey was made in 1987 by employing questionnaire with feedback method, i.e., the answers filled in questionnaire format are compiled to an interim report in March 1988, which has been sent back to responders for revision. The number of VTSs having answered is 160 and, by adding 43 VTSs with the answer in the previous survey, 203 VTSs are surveyed. The number of surveillance radars of surveyed VTSs amounts to 402 which covers about 80% of existing VTS radars in the world. Revised data are analyzed with respect to various factors; category of traffic management, authorities and participants, cost, areas covered by VTS, information and surveillance facilities. Emphases are placed on quantitative analysis to find median values and correlations between closely related factors.
