In order to meet the people living and traffic functions of urban streets, it is necessary to evaluate the integrity of full-factor index of existing streets. Because of the complexity and less relevance of the whole street elements, the method of analytic hierarchy process can be used to select index that include people, vehicles, roads and environment factors, and set up the evaluation index system of target level, criterion level, sub-criterion level and factor level gradually. By using the method of fuzzy comprehensive evaluation, the evaluation matrix of hierarchical structure is calculated from the element level, and the evaluation result of street integrity is obtained by maximum subordinate principle, and then the traffic function and service level of urban streets are evaluated objectively, and comprehensively. Through the investigation and evaluation results of three main urban streets of Tianhe Road, Huangpu Avenue West Road and Xingang West Road in Guangzhou City, the validity of the evaluation method is verified, which provides guidance for the design and high quality improvement of existing urban streets.
