Method and device for generating traffic conditions of divided lanes

The embodiment of the invention provides a method and device for generating traffic conditions of divided lanes and relates to the field of traffic information processing to provide users with more intensive traffic conditions. The method includes the following steps of: obtaining, from a database, the attribute of a road segment within a preset range of a divided lane corresponding to each bifurcation point, wherein the bifurcation point is an intersection node where traffic flow on the divided lane begins to converge or the traffic flow on the road begins to be diverted to the divided lane;setting a buffer region for the road segment within the preset range of the divided lane; acquiring and caching information on vehicle track points within the buffer region within a preset period of time; matching the information on the vehicle track points and the attribute of the road segment within the preset range of the divided lane; calculating the traffic speed of the road segment within the preset range of the div
