The invention discloses a hierarchical road network traffic jam evaluation method, and the method solves the problem in the prior art that evaluation is mostly carried out on the operation state of a single road section. The method specifically comprises the following steps of: firstly, layering urban roads, utilizing a layered sampling method to calculate lowest road section sample sizes of different road sections; secondly, according to a traffic volume and an occupancy rate, utilizing a fuzzy identification method to judge the traffic jam state of each road section; and then, calculating the vehicle driving time, establishing a road network traffic jam evaluation module, and calculating a traffic jam index. Starting with road section traffic jam state analysis, the road network jam state is hierarchically evaluated from microscopic road sections to macroscopic road sections, so that the method is good in good in practicality, and reference bases are provided to traffic management departments for analyzing the jam phenomenon of an urban traffic system in the future.
