For the purpose of efficiency and safety in marine traffic, and considering that ships have to change lane to move on in case of waterway partial closure caused by a marine work zone or an accidence, a new NaSch ship traffic model considering Integrated Bridge System (IBS) is presented, and then a cellular automata model considering IBS for partial reduction waterway is proposed. By numerical simulation, fundamental diagram and time-space spot diagrams of ship traffic flow and that when accidence happens and recovers are given. At last, a numerical example is forwarded to analyze the effect to waterway transit capacity by precautionary area length and ship arrival rate. The model may be applied in decision-making simulation and increase the transit capacity of waterway.
