Abstract
Basic structural properties of Russian railways are explored through the complex network scope. We imply ontology where railway stations portray nodes, while links are represented by trains plying among stations. The information L- network model founded on route is built and its topology is compared with Indian and Pakistan analogues. The network model demonstrates small world properties and its assortative nature. Structural vulnerability is assessed for random attacks, and those on degree and strength targets. Taking into account series of the node centralities, the most important sites are identified as those that could help in clarifying the sensitive points in the network. These sites should be in the focus of pre-protection and post hazard recovery. Also, a P-model is touched and an S- and H- model idea is proposed for further analysis of transportation networks.
Highlights
Based on the complex network theory, a topological analysis of transportation systems becomes a common tool and has been applied for airlines, metro, bus-lines and others in many countries [1,2,3]
There is a lack in such studies concerning Russian transportation systems, i.e. the Russian railway (RR) system
The Russian railway average length of haul is estimated second on the planet; only the US tied with Canada are behind it
Summary
Based on the complex network theory, a topological analysis of transportation systems becomes a common tool and has been applied for airlines, metro, bus-lines and others in many countries [1,2,3]. Russia has about 128000 kilometers of the common-carrier railway network. If we compare it with Pakistan railway network, the latter is a moderate one with over 620 stations and a 7791-kilometer track [4].
