After analysing the characteristics on spatial distribution of road traffic accidents in some areas in China, this paper took road traffic accidents of some provinces/cities in China as an example and thought those provinces/cities as cells. Then the fractal spectrum of road traffic accidents spatial distribution in two-dimensional space and curve was obtained by MATLAB programming based on multi-fractal theory. Because of the preferable linear relation between and , the conclusion of which road traffic accidents spatial distribution satisfies power-law form and accord with multi-fractal distribution was obtained. By calculating the relation of related parameters, this paper analysed the characteristics of road traffic accidents spatial distribution further.
