The invention relates to the technical field of traffic big data assessment, in particular to a traffic big data assessment model construction method. The method comprises the following steps that vehicle traffic data of a target area is collected for a traffic management system, road track point matching is carried out, and vehicle track point matching data is obtained; performing road section vehicle travel analysis on the vehicle track point matching data to obtain a road section travel set; performing road section state analysis on the road section travel set to obtain road section state data; performing dynamic road section state deduction analysis on the road section state data to obtain a dynamic road section state matrix; generating a zone state road network diagram according to the dynamic road section state matrix to obtain the zone state road network diagram; and performing adjacent road section association analysis on the road network diagram with the state to obtain a road section association matrix. According to the method, accurate evaluation of the global performance of the road network under traffic big data is realized through evaluation model construction steps and processes of data driving, multilayer analysis, dynamic description, topological association and dimension expansion.
