Destination prediction method and device

Abstract

The invention relates to the field of intelligent transportation, in particular to a destination prediction method and device. The method comprises the following steps: presetting a destination prediction model, wherein the destination prediction model records the target transfer probability between every two historical location points in each historical running track of a vehicle in each set timeperiod; monitoring the current running track of the vehicle to determine a time period corresponding to the current running track; and based on the time period corresponding to the current running track, using the preset destination prediction model to calculate the prediction probability between the current running track and each historical location point in each historical running track, and determining a corresponding historical location point of which the prediction probability satisfies preset conditions as a predicted destination. The time factor is taken into consideration both in theestablishment of the destination prediction model and in the destination prediction. Therefore, the accuracy of destination prediction is improved, and the driving experience of users is enhanced.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a destination prediction method and device. Background technique [0002] With the development of Internet technology, location-based service (Location Based Service, LBS) applications continue to emerge, so as to provide users with services such as location positioning, route query, and historical driving trajectory presentation for driving. [0003] Since the user's driving route will be affected by both his own behavior habits and the constraints of external conditions, the destination of the user's driving travel has certain rules, and the possibility of the user's driving to certain specific areas Relatively high, such as homes, companies, shopping centers, restaurants, and movie theaters. [0004] Under the existing technology, the terminal can obtain the historical driving trajectory of the user's driving travel through the application program of the location ser...

Problems solved by technology

[0009] Embodiments of the present invention provide a destination prediction method and device, which are used to predict the destination of the user's driving trip based on the current driving trajectory and historical driving trajectory of the vehicle driven by the user, which solves the problem of using historical driving trajectory in the prior art. The accuracy of the destination prediction is too low when the destination is predicted
