考虑游览船运营特征的航道通过能力评价方法

为构建客货船舶协同动态运行控制技术体系,以经典航道通过能力模型为基础,构建基于游览船运营特征(发船高峰性和航线集中度)的航道通过能力模型.根据黄浦江游览核心区船舶自动识别系统(AIS)数据,对所提出的航道通过能力模型进行实证分析.研究结果表明,本文航道通过能力模型能够较为准确地评价研究区域的实际航道通过能力.游览船发船高峰时期与现有航线规划条件下,黄浦江游览核心区航道通过能力(76艘/h)趋近饱和状态;当过境船到达超过69艘/h时,建议海事相关部门采取“错峰”航行等相关政策.

A Capacity Estimation Approach for Waterway Traffic Considering Operational Characteristics of Cruise Ships

A new capacity estimation model for waterway traffic is derived from the classic traffic capacity model by considering the operational characteristics of cruise ships. According to the ship automatic identification system (AIS) data, a case study on Huangpu River Cruiseis applied to testify the applicability of the proposed model in estimating the traffic capacity of the core water area. Results show that the proposed model could provide an accurate estimation on the traffic capacity for this area. The traffic capacity reaches 76 ship/h under the current traffic compositions in the Huangpu River channel. When the ship traffic flow is larger than 69 ship/h, the maritime operators are suggested to take capacity management measures such as "Peak Restrictions".
