This paper choices eleven evaluation index to establish fuzzy hierarchy evaluation index system of urban road intersection based on basic facilities, operation conditions and environment level of intersection. Comprehensive evaluation modal of urban road intersection is established by calculating relative weight of every layer through applying to triangular fuzzy function. Ten intersections obtain comprehensive evaluation based on the modal established. These intersections have been clustered three clusters by K-Means Cluster method finally. It is help to manage and control the similar intersections according to cluster result.
