【摘要】：随着船舶向大型化方向发展的趋势日渐明显,船舶对通航条件的要求越来越高。受航道宽度、水深等方面的影响,部分航道难以满足大型船舶自由航行的需要,因此,需在通航时间段内针对不同船舶提供不同的通航服务,以保证船舶安全运行。文章引入区分服务理论,根据船舶对航道资源的占用情况将交通流分解为常规状态交通流和区分服务状态交通流,在此基础上建立时间区分服务航道系统模型,并以舟山水域条帚门航道为例进行仿真实验。结果表明,该模型能够较好地反映上述非流畅交通流的运行状况,对交通流组织、运行状态的评估和预测具有一定参考意义。
[Abstract]:With the trend of ships becoming larger and larger, the requirements of navigation conditions are becoming higher and higher. Due to the influence of channel width and water depth, it is difficult for some waterways to meet the need of free navigation of large ships, so it is necessary to provide different navigation services for different ships in the navigable time period in order to ensure the safe operation of ships. In this paper, the theory of differentiated service is introduced to decompose the traffic flow into conventional traffic flow and differentiated service traffic flow according to the ship's occupation of waterway resources. On this basis, a time-differentiated service channel system model is established. The simulation experiment is carried out by taking the broomgate channel in Zhoushan water area as an example. The results show that the model can well reflect the operation status of the above non-smooth traffic flow and has a certain reference significance for the evaluation and prediction of traffic flow organization and operation state.
