桥区航道船舶通过能力仿真

Channel capacity simulation in the bridge area waterway

为合理分析计算桥区航道船舶通过能力,根据武汉长江大桥桥区航道船舶AIS数据及实测数据,分析船舶类型比例、船舶尺寸分布规律、船舶到达速度分布规律、船舶到达规律分布和船舶间时距等数据特征,利用VC编程生成仿真船舶交通流,并嵌入电子江图,实现数据的可视化输出.建立桥区航道船舶通过能力仿真模型,通过数据输出及分析处理,实现桥区航道船舶通过能力的分析计算,可为桥区航道规划设计及航道整治提供理论依据.

To analyze the channel capacity in the bridge area waterway reasonably, the proportion of different ship types, the distribution of ship size, ship reaching, ship reaching speed as well as time interval between ships were analyzed based on the AIS and measured data of ships in the Wuhan Yangtze river bridge area. On this basis, the ship traffic flow were simulated by using Visual C ＋ ＋ platform, and the data visualization output were realized after imbedding the inland waterway electronic chart. The simulation model of channel capacity in the bridge area waterway was built, so the channel capacity in bridge area waterway can be calculated, which can provide theoretical basis for the channel planning design and regulation.
