Abstract: To accurately describe the difficulty of cognitive traffic in the view of traffic managers, a method for quantitative calculation of marine traffic macroscopic flow complexity was proposed. The similar ships were cataloged into a traffic cluster; According to the historical traffic flow field by interpolation method, the aggregation complexity, the speed-diachronic complexity and the density-diachronic complexity were evaluated. The cognitive complexity was obtained by the marine traffic macroscopic flow complexity, showing the cognitive complexity in the macroscopic complexity map. The simulation experiment shows the macroscopic complexity model is available for demonstrating the distribution of complexity in space.

Key words: traffic cluster, traffic flow, aggregation complexity, speed-diachronic complexity, density- diachronic complexity
