Large scale marine constructions such as an offshore airport and reclaimed land in ports and harbors change the topographical environment of water area and affect the marine traffic. The risk assessment of marine traffic for limited water area has been carried out from the viewpoint of mariners. In this paper, the authors proposed an evaluation method of marine traffic for wider water area, namely a macroscopic evaluation method, where the concept of Voroni Medial Axis (VMA) is taken into consideration. The VMA is obtained by computing the Voronoi Diagram for boundary points of the image of concerned water area, and extracts a simple continuous line. By applying this method, the results of the macroscopic evaluation for the topographical environment of harbor water areas was obtained.
