| 内河航道服务区是沿航道布置的通航辅助设施，为过往船舶和船员提供锚泊和补给服务，其水域面积是内河航道服务区规划设计中的关键问题。考虑到船舶进入服务区和服务时间的随机性，本文提出了基于船舶交通流特性和服务特征的仿真模型用于分析服务区水域面积。以长三角地区典型航道服务区为例，基于AnyLogic?平台的仿真结果表明，模型预测的服务区停泊船舶数量和水域面积与实际情况吻合良好。敏感性分析表明，服务区停泊船舶数量与航段上船舶流量、服务特征参数的均值成线性正比关系，与服务特征参数的概率分布类型关系很小。基于调查参数和回归分析，可将服务区水域面积简化为航段上船舶流量和船舶平均吨位的连续函数，有助于方便合理地估算服务区所需的水域面积。 |

| Abstract: |
| Inland waterway service area (IWSA) is an important auxiliary navigation facility along the inland waterway, which provides special services including berthing and replenishing of daily necessities for vessels and mariners during their voyages. The water area and maximum number of vessels that can be accommodated simultaneously is vital for the planning and designing of an IWSA, which is associated with the category of service, passing vessel flow rate, demand probability (driving-in rate) and service duration (turnover rate).Taking into account the randomness of the dynamic traffic system and service duration, in this article, a simulation model using AnyLogic? for estimating the water area of an IWSA based on the characteristics of inland vessel traffic and service functions was presented. Based on field data regarding three service areas on three different inland waterways in the Yangtze Delta, the validation showed that compared to the empirical formulas, the forecasted water areas and number of the berthed vessels using the simulation model were in good agreement with the actual operation. The sensitivity analysis was adopted to identify the impacts of different distributions and expected values of the driving-in rate and turnover rate on the water area of an IWSA. According to the simulation and regression analysis, the water area could be simplified to a continuous function of the flow rate and averaged tonnage of vessels on the corresponding inland waterway. It provides a convenient and reasonable estimation for the required water area of an IWSA. |
