The invention relates to an intelligent identification method of a road traffic status. In the method, road section traffic statuses are defined into five grades of smoothness, normality, crowdness, blockage and severe blockage, and traffic flow ratios and occupation ratios are both defined into five grades of very small, small, medium, large and very large; a fuzzy reasoning method is used for intelligently identifying the road section traffic statuses; mode combination is carried out to form a fuzzy relation according to the traffic flow ratio, the traffic occupation ratio and a traffic status rule, and then actual measurement data of the traffic flow ratio and the occupation ratio is used as an input to work out a fuzzy set; and finally, the traffic status at that time is obtained by adopting fuzzy decision. The invention has the advantages that the traffic status is synergetically measured by the two main parameters: the traffic flow ratio and the occupation ratio, thus the accuracy is high; only one traffic flow detector needs to be arranged for measuring the traffic flow and the occupation ratio, thus the site construction cost is lower; and the traffic statuses are expandedto five grades, thus the integrity and the systematicness are high.
