Summary:
Metro systems carry a large volume of commuters around in major cities and their efficiency depends on multiple factors including the connectivity of subway lines, train schedules, passenger distributions, management quality, etc. In this paper, we study the network properties of five metro systems (Beijing, Hong Kong, London, Paris and Tokyo) and compare their relative network efficiency in terms of two proposed metrics, namely, average station density and station load. It is shown that among the five systems, the Tokyo system has the shortest characteristic path length (shortest average travel distance between two stations), as well as highest efficiency in carrying passengers around the city. Furthermore, the London metro has a better tolerance to faults in a local scale, and the Paris system outperforms others in terms of level of convenience to commuters due to its high station density and low load.
