摘　　要：中国沿海航路体系网络化发展布局的确立,将产生大量繁忙的船舶交通流汇聚水域,其中船舶定线制警戒区因船舶密度大、交通流向复杂、航行危险大,已成为沿海航路体系安全运行的一个薄弱和重点环节。为深入探讨警戒区优化设计,利用交通冲突技术的研究方法,以警戒区交通流冲突为重点内容,提出改警戒区小角度斜交航道交叉为大角度或正交,以及警戒区渠化交通设计等方法。力图减少警戒区交通流冲突点数量,降低冲突强度,改善微观层面的船舶危险会遇状况,进而寻求警戒区几何设计、交通控制的一些基本要求和原则,为船舶定线制方案设计和交通控制措施制定提供决策依据。The development of China＇s mesh like coastal seaway system will bring about busy vessel traffic intersection at certain areas. Because the traffic flows in all directions converge in precautionary areas, the density of traffic streams, hence, the probability of collision happening gets very high. Therefore, the routeing scheme of precautionary areas will be the critical measure to ensure the safe operation of the seaway system. For optimizing the precautionary area design navigational traffic conflict technique is applied. With the focus on navigational traffic flow con- flict, the methods of stream channelization and making intersection angle rectangular for reducing the number of traffic conflict points and conflict intensity are put forth. The geometric optimization design of the precautionary area and the principles and requirements of traffic control in the areas are given to help to decide the routeing scheme and the traffic control measures.
