In the era of e‐Navigation, the future VTS is anticipated to play an important role on the enhancement of maritime safety and the efficiency of maritime transport as a key stakeholder of e‐Navigation. The VTS services need the advanced Traffic Organization Service(TOS). In this paper, the VTS functions for TOS is revisited from the reports of IMO e‐Navigation Correspondence Group and IALA VTS Committee. In Korea, the research activities to enhance the existing VTS functions have been conducted. In terms of TOS, some VTS functions have been developed. In conclusion, all the past traffic data and real‐time ship data are required to provide the advanced TOS. For this, the advanced functions to support TOS should be implemented on VTS console.
