METHOD AND APPARATUS FOR BUILDING ROUTE TIME CONSUMPTION ESTIMATION MODEL, AND METHOD AND APPARATUS FOR ESTIMATING ROUTE TIME CONSUMPTION

A method and apparatus for building a route time consumption estimation model, and a method and apparatus for estimating a route time consumption are provided. The method comprises: obtaining training data from user trajectory data; obtaining the route time consumption estimation model by using the training data, wherein the route time consumption estimation model comprises: a road condition subnetwork estimating road condition feature representations of road segments included by the route by using the time information and road network feature representations of road segments included by the route; an integration subnetwork determining an estimated time consumption on the route according to a feature representation of the time information, vector representations of the road segments included by the route and road condition feature representations of the road segments included by the route; a training target of the route time consumption estimation model is to minimize a difference between the estimated time consumption and an actual time consumption on the route. The accuracy of the estimation of time consumption on the route can be improved.
