Transportation Network Analysis in the Chukyo Metropolitan Area

Abstract

Studies analysing metropolitan areas utilize many forms of analysis and indices. In this study, network analysis based on graph theory is adopted to investigate traffic patterns in the Chukyo metropolitan area.
In the first stage of the study, I utilized a measure of degree of connectivity based on graph theory in order to analyse the development of transportation network in the area from 1952 to 1978. The second stage was an investigation of regional transportation network structure in 1978, using an accessibility measure, also based on graph theory.
Results of this study show a highly-developed transportation network. The railway system, which was developed prior to 1952, remained relatively unchanged during the study period, however, there was remarkable development of the bus system between 1952 and 1978.
The complicated structure of the Chukyo regional system, centering on Nagoya city is ilustrated in figure 8. Figure 9 shows the connections among municipalities within this system.
In order to provide more precise analysis, comparative studies of other regional system are required.
