In order to i皿 prove the 皿 arine traffic safety in narrow channels or inside ports and har − bours ， the judgement criteria must be established based on the mariners ' perception of safety ． In the present paper ， a quantitative expression model of the mariners ' perception of safety is proposed ． This model takes into account two kinds of perception of safety ； one is against the structural obstacles and the other is against the encountering ships ． The extraction of mariners
