The invention discloses a highway running state evaluation method based on a macroscopic fundamental diagram. The highway running state evaluation method comprises the following steps of: step 1: pre-processing data; step 2: calculating macroscopic fundamental diagram model parameters; step 3, establishing a macroscopic fundamental diagram model; step 4, designing and implementing a clustering method DBSCAN; and judging traffic state of a road network through giving data of highway toll stations according to a data class threshold value range obtained finally. The highway running state evaluation method is suitable for a highway network, utilizes actual toll data of highways, ensures that the result is real and effective, determining major parameters of the macroscopic fundamental diagram of the highway network through calculating average flow rate and average occupancy of the highway network, and provides a basis for modeling, thus the model can reflect the highway network macroscopic running state and evolution process thereof intuitively.
