A new kind of traffic separation mode for the two-way channel was proposed primarily by extending the channel to left for the heavy traffic side during the peak period, forming a new kind of channel--Tidal Reversible Channel. This method can improve the general navigation efficiency and meet the navigation demands of both sides of the channel at the same time. The two key points of the reversible channel which are the operation occasion and the reversible width of the channel, called Dynamic Time and Dynamic Zone, were discussed, also their further research directions. Then, the feasibility of the new channel was verified by two different design ships in Yangtze River Estuary Deep-Water Channel, indicating that the reversible channel will have wide study and application prospect.
