Analysis of Qingdao’s Public Transport Line Network

Public Transport Line Network(PTLN) reflects the whole city’s public transport environment. According to the analysis of PTLN, the problem in public transport could be found easily, which is the base of the improvement of transport capacity. The statistical character of Qingdao’s PTLN is analyzed from the view of the Complex Network in this paper. First, the definition of the PTLN is given, based on which Qingdao’s PTLN is built. Then the degree value distribution, degree distribution, the relationship between the number of bus stations and the degree of the node which stands for the bus line and the distribution of network weight is analyzed. Some network’s statistic features such as the average degree of the network, the shortest average path length and the average of the weigh are calculated. The results show that Qingdao’s Public Transportation is rather convenient.
