A systematic analysing procedure is needed to assess the marine traffic safety in the congested and the confined water area. Three fundamental steps should be taken into account in this procedure ; (1) the evaluation of the burden due to environmental conditions, (2) the evaluation of the load due to ship manoeuvering and (3) the evaluation of the hidden risk in the ship handling process. In the present paper as the first report of this research work, a quantitative assessment model is proposed to evaluate the stress level which is burdened to mariners under the conditions of the traffic congestion and the geographical restriction. This model makes special features of (1) the capability to aggregate the geographical environment stress and the traffic environment stress by employing the same algorithm and (2) the conquest of the lack of judgement criteria whether it is acceptable or not. This will become one of advantageous models as the assessment method of the marine traffic safety.
