Abstract

The urban road network shares self-similarity and is suitable to adopt the fractal theory for analysis. The fractal dimension of the urban road network reflects the completeness of the road system. The employment of fractal theory to analyze the urban road network can reflect the feasibility of the urban road network layout and is of vital significance to the evaluation of the urban road network planning. GIS has strong space analysis function and can directly show the analysis process. To use the fractal theory to analyze the urban road network on the GIS platform can provide a new idea for the evaluation of the urban road network. Based on the GIS platform, this paper employs the fractal theory to the analysis of Shenzhen's municipal road network. Hausdorff method is adopted to calculate the index of the road network coverage, analyze the calculation results and put forward suggestions to optimize the road network.
