Abstract: The fractal theory is adopted to analyze the fractal consistency between traffic network and urban morphology for medium and small cities, aiming at a better coordination of the two. Considering the non-uniformity from center to marginal areas, the radius dimension is used for the fractal quantitative description in order to ensure the comparison and aggregation, and the coordination factor is defined in order to measure the matching degree in the gradual changes from center to margins. On the basis of the structural and fractal characteristics of medium and small cities, a judgment standard for coordination is established and the consistency between traffic network and urban morphology is investigated. The high coincidence of experimental results and actual urban development demonstrates the feasibility of this method.
