在交通规划工作中，关键路段识别有助于评价所设计的网络方案的脆弱部分。提出了一种新的基于容量的网络鲁棒性指标，用于识别关键路段和评价交通系统性能。它使用总网络容量的变化作为评估措施。采用先进实用的网络容量模型来估算交通系统的吞吐量。为了有效地求解实际容量模型，提出了一种基于灵敏度分析的算法。基于能力的网络鲁棒性指标识别出对整个网络的运输能力起关键作用的链路。基于容量的网络鲁棒性指标是对现有网络评价指标的有效补充。通过实验验证了基于容量的网络鲁棒性指标与基于效率的网络鲁棒性指标之间的差异。在网络鲁棒性指标不显著的情况下，基于容量的网络鲁棒性指标可以作为一种实用的度量方法。
In transportation planning works, critical links identification is helpful to evaluate the vulnerable parts of the designed network schemes. A new capacity-based network robustness index is presented for identifying critical links and evaluating the transportation system performance. It uses the change of the total network capacity as an evaluation measure. The advanced practical network capacity model is employed to estimate the throughput of transportation system. A sensitivity analysis based algorithm is also developed to solve the practical capacity model efficiently. The capacity-based network robustness index identifies the links which play critical roles in the transportation capacity of the whole network. The capacity-based network robustness index is an effective supplementary to the existing network evaluation indices. The experiments demonstrate the differences between the capacity-based network robustness index and the efficiency-based network robustness index. The capacity-based network robustness index can be used as a practical measure in the situations where the network robustness index is not significant.
