摘要
采用交管中心的雷达和雷达数据处理器等设备采集天津港大沽锚地、大连港大连湾锚地、荣成湾锚地和青岛港第22号锚地中锚泊船船位数据,并人工量取锚船之间的距离.用概率论中的Γ分布对锚泊船之间距离的数据进行拟合研究.结果表明,可以用Γ分布近似描述锚泊船之间距离的概率分布规律.这项研究可以为船舶交通管理和锚地规划提供理论依据.
Observations on the positions of anchored vessels have been taken at the anchorage of the harbour of Tianjin, Dalian, Qingdao and the Bay of Rongcheng by using radar, the radar data processor and other equipments at the VTS centers. The data of distance between anchored vessels in the anchorages have been measured manually. The goodness of fit test have been done for the observed frequencies and the expected freqencies of gamma distribution. The conclusion is that the gamma distrabution can be used to discribe the probability distribution of the distance between anchored vessels in an anchorage. The study can be a scientific basis for anchorage planning or anchorage traffic management.
