GIS-Based Analysis on Transportation Network Features of Garden City Model

摘要

Network structure is generally used to represent and study urban transportation system. This research works on the digital model of classical planning theory Garden City, and calculates the network macroscopic topological properties of radial and ringy crossing urban transportation system. The extraction of topology structure of the digital Garden City and the calculation and analysis of topology parameters of the transportation system including degree, clustering coefficients and K-Core are the main two parts of the research. Conclusions can be drawn that higher-valued nodes for the three parameters are basically coincident, which mainly are the crossings of the first, second and third avenues and boulevards and streets. Further research on digital Garden City's transportation system would be meaningful.
