Abstract: A method and apparatus for predicting a road condition, a device and a computer storage medium are disclosed. The method includes: determining at least two continuous road segments obtained by dividing a navigation path; and performing the following processing on each road segment one by one from the starting point of the navigation path to the end point thereof respectively: determining the moment when the user reaches the road segment processed currently; predicting road condition information of the road segment processed currently at the determined moment; and predicting passing duration of the user at the road segment processed currently based on the road condition information of the road segment processed currently at the determined moment. With such a road-condition prediction mode, the road condition at the moment when the user will reach each road segment in the future may be predicted, and compared with the mode of predicting the road condition based on the user query moment, more accurate road condition information may be provided.

Abstract: A route recommendation method, an electronic device, and a storage medium are provided, which relate to the field of intelligent recommendation. The method includes: acquiring i-th scenic area information input for a target itinerary, wherein i is a positive integer; updating a scenic area list of the target itinerary based on the i-th scenic area information, and determining an estimated tour duration based on the scenic area list; and determining a recommended route of the target itinerary based on the scenic area list, in a case where a difference between a planned itinerary duration of the target itinerary and the estimated tour duration is less than a preset threshold.
