    摘要:

    城市地下通道畅通可靠度的分析和计算对城市道路路网的畅通性和安全性意义重大。通过分析现有研究成果,对城市地下通道运行特点进行了研究,提出了几种关于城市地下通道畅通可靠度的计算方法,分别为基于地下通道功能函数、饱和度、车流密度和交通流统计。以武汉东湖通道为例,证明算法计算得到的东湖通道畅通可靠度与实际调查得到的交通状况一致。结果表明,利用畅通可靠度分析城市地下通道运行状态具有实用性。

    Abstract:

    The analysis and Calculation of unblocked reliability of urban underpass are very important to the accessibility and safety of the road network in the whole city. By analyzing the existing study results, the operation characteristics of urban underpass are studied. Several calculation methods of urban underpass reliability are proposed, which are based on the underpass functions, saturation, traffic flow density and traffic flow statistics. Taking East Lake Channel in Wuhan as an example, it is proved that the reliability of the East Lake Channel calculated by the algorithm is consistent with the traffic conditions obtained by the actual investigation. The result shows that it is practical to analyze the operation state of urban underpass by using unblocked reliability.
