Problems solved by technology

[0003] At present, the estimation of ETA generally uses the machine learning algorithm to input the feature value of the entire route into the machine learning algorithm for training and prediction. However, this method only considers the overall characteristics of the route, and only considers the Overall features lead to lower accuracy of time-of-arrival estimates

Abstract

The embodiment of the present application discloses a method and device, electronic equipment, and storage medium for estimating the arrival time of a route. The method includes: obtaining the overall route characteristics of the route to be estimated, and at least one of the route scene label; according to the overall characteristics of the route and the route scene label, obtain the initial estimated arrival time of the route to be estimated in each route scene; put the route to be estimated in each route The initial estimated arrival time in the scene is combined with the overall feature of the route to obtain the joint route feature of the route to be estimated, so as to predict the estimated arrival time of the route to be estimated according to the combined route feature. The technical solution of the embodiment of the present application can improve the estimation accuracy of the route arrival time.

Description

Route arrival time estimation method and device, electronic device, storage medium technical field The application relates to computer technology field, specifically, relate to a kind of route arrival time estimation method and device, Electronic device, computer readable storage medium. Background technique The navigation software provides the user with the function of planning the route, and performs the voice along the road for the user during the user's driving process. guide. Estimated Time of Arrival (ETA) is a basic function in map software. Specifically, for a route and departure time determined on the map, the time required to complete the route is given. At present, the estimation of ETA is generally to use machine learning algorithm to input the eigenvalues ​​of the entire route into machine learning algorithms. However, this method only considers the overall characteristics of the route, and only considers the overall characteristics of the route Fea...
