近年来,由于自然灾害,不断地环境恶化以及不可预测的灾害侵袭,突发事件时有发生,突发事件可能对交通网络产生非常严重的影响。本文给出了一些指标来表征突发事件对交通网络的影响程度。这些指标适用于用户最优、系统最优以及效率损失等情形。我们给出了这些指标的性质并讨论了在用户最优、系统最优以及效率损失等情形下的指标之间的关系。交通网络的数值算例表明了关于突发事件的指标的合理性。突发事件对交通网络的影响程度评估对于道路规划、道路维护以及网络脆弱性分析均有重要意义。
近年來,由于自然災害,不斷地環境噁化以及不可預測的災害侵襲,突髮事件時有髮生,突髮事件可能對交通網絡產生非常嚴重的影響。本文給齣瞭一些指標來錶徵突髮事件對交通網絡的影響程度。這些指標適用于用戶最優、繫統最優以及效率損失等情形。我們給齣瞭這些指標的性質併討論瞭在用戶最優、繫統最優以及效率損失等情形下的指標之間的關繫。交通網絡的數值算例錶明瞭關于突髮事件的指標的閤理性。突髮事件對交通網絡的影響程度評估對于道路規劃、道路維護以及網絡脆弱性分析均有重要意義。

The poor maintenance of transportation (road)networks, natural disasters, and unforeseen attacks lead to the emergency .This paper proposes emergency impact assessment indices to evaluate the emergency effects of link in transportation(road)networks.We also construct the link importance indices that allow for the ranking of links in transportation networks in terms of their emergency importance , should they be destroyed due to the e-mergency(natural disaster, great incident, great congestion, broken-down bridge, and etc.).The indices are applicable in the case of user-optimization, system-optimization and efficiency loss .We give the property of the indicators and discuss the relationship between the indices in the case of user -optimization , system-optimization and efficiency loss .Numerical transportation network examples illustrate the proposed qualitative emergency indi-ces.The evaluation of the link importance is very important to the road plan , road maintenance and network vul-nerability analysis .
