| 摘 要： | 提出内河桥区船舶交通流量分析的数学方法,以2008-2009年荆州长江大桥的船舶交通流量观测数据为基础,分析了内河船舶的抵达分布规律。依据国家标准GB/T4089—2008,使用双侧检验的方法对泊松分布参数进行了假设检验。其结果表明：荆州长江大桥水域船舶24 h内船舶流量分布符合泊松分布,船舶相隔到达时间符合二项分布,该模型的分布参数=7.82,经双测检验符合国家标准。 |
| 关 键 词： | 船舶流量 泊松分布 假设检验 二项分布 |

| Abstract: | Inland waterway vessel traffic flow is discussed by the statistic data during the years 2008 and 2009 in Jingzhou Yangtze River Bridge and hereby the arriving distribution model is proposed.In accordance with the statistical interpretation of data（GB/T 4089-008）,the parameter of arriving distribution model has been examined.It concludes that passion distribution fits the arriving distribution model with the parameter=7.82 and the separation time discipline is binomial distribution in Jingzhou Yangtze River Bridge waterway.This method helps to master the ship traffic distribution along the Yangtze River,and the supervision of navigable waterway situation and early-alerting management in practice. |
