Analysis of Guangzhou metro network based on L-space and P-space using complex network

In this paper, two different topology types (including L-space and P-space) were introduced to build the networks for Guangzhou metro. Some important parameters were calculated, such as, degree, clustering coefficient and average distance of network. And the key stations, average shortest distance, average shortest time-spent, average transfer times were obtained for analyzing the characteristic of Guangzhou metro. In L-space networks, the average degree is 2.092. Only a few stations have high degree, such as, Tiyuxilu. They become the key stations of Guangzhou metro. The average shortest distance, the average pass-by stations and the average shortest time-spent between any stations is 21.08km, 13.44 and 27.38min separately. In P-space networks, the average degree is 40. Among the stations, Guangzhou railway station has the largest degree of 92. Experiments showed that the average shortest distance of the network is 2.35, that is, it need transfer 1.35 times to reach the other station.
