Заглавие: AN APPLICATION OF THE GRAPH THEORY WHICH EXAMINES THE METRO NETWORKS
Ключови думи: metro network, graph theory, cluster analysis

Абстракт: The Graph theory gives a mathematical representation of transport networks and allows us to study their characteristics effectively. A research of the structure of metro system has been conducted in the study by using the Graph Theory. The study includes subway systems of 22 European capitals. New indicators have been defined in the research such as a degree of routing, a connectivity of the route, average length per link (which takes into account the number of routes), intensity of the route, density of the route. The new and the existing indicators have been used to analyze and classify the metro networks. The statistical method cluster analysis has been applied to classify the networks. Ten indicators have been used to carry out an analysis. The metro systems in European capitals have been classified in three clusters. The combination of the both two methods has been used for the first time in this research.
