Problems solved by technology
However, in many cases, the positioning information is not accurate enough. For example, a certain drift may occur in a dense road network area, which may cause problems with the starting point binding road, such as reverse binding, resulting in users receiving wrong broadcast information. In turn, it may cause users to make wrong driving behaviors and cause violations, etc.

This application discloses a starting point road binding method and a prediction model acquisition method, device, and storage medium, which relate to the field of intelligent transportation. The road is determined as a candidate road; every two different candidate roads form a road pair, and any two road pairs are not the same; for each road pair, according to the current user's state information and the two candidate roads in the road pair The attribute information of the road is used to construct the characteristics corresponding to the road pair, and input the prediction model obtained in advance to obtain the prediction result, which includes the navigation starting road selected from the two candidate roads in the road pair; The correct prediction result finally determines the navigation starting point road. Applying the scheme described in this application can improve the accuracy of the result of tying the road at the starting point.
Description
technical field [0001] The present application relates to the field of computer applications, in particular to the method, device and storage medium for starting-point road binding and prediction model acquisition in the field of intelligent transportation. Background technique [0002] The route calculation function is an important function in driving navigation, and the route calculation function is inseparable from the correct starting point binding road, that is, correctly determining the user's navigation starting point road. [0003] At present, the nearest road is bound by calculating the distance mainly based on the user's positioning information, that is, the road with the closest distance is determined as the starting point road of the navigation. However, in many cases, the positioning information is not accurate enough. For example, a certain drift may occur in a dense road network area, which may cause problems with the starting point binding road, such as rever...
