統計値と水域形状を用いた交通環境のマクロ的評価

抄録

The technique of simulation is often used to evaluate the traffic condition in the present or in the future. However, the special devices, observed data, and high cost are needed to carry out the simulation. In addition, as the simulation process is too complicated, so that such simulation method is not easy to understand for the person who is not having speciality knowledge. In this paper, the authors estimated the network of maritime traffic by utilizing the statistical data of ships' port entry and the simplified figure of water area of the port. The estimation of number of encountering ships was attempted without such special devices and observed data, and compared with the observed number. Moreover, application to the prediction of traffic environmental condition was indicated.
