论文摘要
如果遇到干扰，可以在运输网络中重新路由的可用替代路线至关重要。在正常操作条件下，在匈牙利铁路网络中确定了在正常操作条件下流量较小但在干扰情况下的重要性较小的线段。为了描述单个替代路线的良好性，使用了所谓的冗余指数。结果表明，网络的结构很好，但是冗余最高的线（根据国家铁路运营商Máv的编号，第80、2、4和77号线）大多是单个跟踪的，在许多情况下，线路速度较低。建造其他轨道并为这些线路电气化，同时仍在维护现有的柴油机机车以进行电动支持的情况下，这是使匈牙利可持续发展的相当密集的铁路网络的性能的钥匙。
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.
