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.

Abstract

The invention discloses a start point binding method and device, a prediction model acquisition method and device and a storage medium, and relates to the field of intelligent transportation. The start point binding method can comprise the steps: determining a road in a preset range around a positioning point where a user is located as a candidate road when the user initiates driving navigation road calculation; forming a road pair by every two different candidate roads with any two road pairs being different; for each road pair, constructing features corresponding to the road pair according to state information of the current user and attribute information of the two candidate roads in the road pair, inputting a pre-trained prediction model, and obtaining a prediction result which comprises a navigation starting point road selected from the two candidate roads in the road pair; and integrating the prediction results of different road pairs to finally determine the navigation startingpoint road. Thus, the accuracy of the start point binding result is improved.

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...
