A space traffic characteristic Kernel-KNN matching road traffic state obtain method comprises the following steps: firstly, extracting representative road traffic data of a target road section and space related road sections, and setting up a road traffic running characteristic reference sequence after data pre-treatment; then selecting a space road traffic data sequence, and forming a space road traffic data sequence Mercer core; finally selecting the space road traffic characteristic reference data sequence and a present space road traffic characteristic sequence, obtaining an Euclidean distance in characteristic space between the space road traffic characteristic reference data sequence and the present space road traffic characteristic sequence, using a KNN method to select traffic states of k roads of the target road section, and finally using weight average to obtain the road traffic state of the target road section. The method can carry out real time effective dynamic evaluation of road traffic running state, and can effectively obtain road traffic state with good accuracy.
