The invention discloses a road condition calculation method, device, equipment and medium based on clustering. The method includes obtaining the driving trajectories of a preset number of vehicles in a long road section; segmenting along the vehicle traffic direction of the long road section to obtain a corresponding short-circuit section sequence; The short-circuit section sequence obtains the interval driving trajectory set corresponding to each short-circuit section; according to the interval driving trajectory set corresponding to each short-circuit section, the comprehensive vehicle speed sequence corresponding to the short-circuit section sequence is obtained; scanning the comprehensive vehicle speed sequence, along the comprehensive vehicle speed sequence Carry out vehicle speed clustering in the element arrangement direction to obtain a clustering result set; cluster the short-circuit sections in the short-circuit section sequence according to the clustering result set to obtain the target road section sequence; calculate each target in the target road section sequence according to the clustering result set The traffic condition of the road segment. The formation basis of the target section of the present invention is more objective and conforms to the real situation in the real world, thereby providing users with accurate road condition services and increasing user viscosity.
Description
technical field [0001] The present invention relates to the field of road condition calculation, in particular to a cluster-based road condition calculation method, device, device and medium. Background technique [0002] The vehicle traffic state data is important data required for map navigation. In the prior art, the vehicle traffic state corresponding to a road segment or road segment group can be determined by calculating the vehicle speed of each road segment or road segment group in the map, and then the road conditions of the road segment or road segment group can be obtained. . [0003] Compared with road segment groups, road segments are divided into finer granularity. Therefore, determining vehicle traffic status at road segment granularity is beneficial to provide users with more accurate vehicle traffic status data and increase user stickiness. However, the lengths of different road sections vary greatly. For example, the length of short-circuit sections may be...
