| 摘 要： | 为了提高内河航道通过能力,分析了船舶交通流的到船分布和船头间距分布特性。以西江航道2004年日到船统计量为样本,运用数理统计方法,给出了日到船分布与船头间距分布的假设检验,运用时间保证率方法将实测数据点与概率分布的理论值进行了比较。比较结果表明其相对误差均在5%以内,说明内河航道日到船艘数服从正态分布,日船头间距近似为爱尔朗分布。

| Abstract: | In order to improve inland waterway capacity,the arrival distribution and headway distribution of vessel traffic flow were analyzed.Based on the data of ship arrival in Xijiang waterway in 2004,the average values of daily-arriving-ship quantity and headway were assumed by mathematical statistics,the observed values of vessel traffic flow were compared with the ones of theory computation by time guarantee percentage method.The result shows that their relative errors are within 5%,the daily-arriving-ship quantity is close to Normal distribution,the headway is close to Erlang distribution in inland waterway. 9 tabs,4 figs,9 refs. |
