匈牙利铁路网冗余度分析
Redundancy Analysis of the Railway Network of Hungary
摘要：
在交通中断的情况下，可以改变交通路线的可用替代路线对交通网络至关重要。在匈牙利的铁路网中，通过使用加权有向图，确定了在正常运营条件下交通量较少但在中断情况下重要性增加的路段。为了描述各个备选路由的优良性，使用了所谓的冗余指数。结果表明，网络结构良好，但冗余度最高的线路（根据国家铁路运营商编号，MÁV，80号，2号，4号和77号线）大多是单线，在许多情况下，线路速度较低。在电力支持中断的情况下，建设额外的轨道并对这些线路进行改造，同时仍然保持现有的内燃机车，这是使匈牙利相当密集的铁路网络可持续发展的关键。
英文摘要：
Available alternative routes on which traffic can be rerouted in the case of disruptions are vital for transportation networks. Line sections with less traffic under normal operational conditions but with increased importance in the case of disruptions are identified in the railway network of Hungary by using a weighted directed graph. To describe the goodness of the individual alternative routes the so-called redundancy index is used. The results show that the structure of the network is good, but the lines with the highest redundancy (lines No. 80, 2, 4 and 77 according to the numbering of the national railway operator, MÁV) are mostly single tracked and in many cases the line speed is low. The building of additional tracks and electrifying these lines while still maintaining the existing diesel locomotives for the case of disruptions of the electric support are the keys to make the performance of the rather dense railway network of Hungary sustainable.
