Embodiment Construction

[0056] In order to facilitate the understanding of the scheme of this application, some terms involved in this application are explained first:

[0057] Route, in the map route is a completed route connecting the start point and the end point. In actual scenarios, the length of the route generally ranges from one kilometer to more than ten kilometers.

[0058] A road segment, a road segment is a unit of a route. In the map, a route is divided into one or more line segments, each line segment is a road segment, and each road segment can correspond to a unique identifier. For example, the route is divided into multiple road sections according to each small block involved in the route. Correspondingly, a route can be regarded as a segment sequence composed of one or more segments. In general, a segment is a part of a route, and in the case of a shorter route, the route itself is a segment.

Abstract

The present application discloses a method, device and computer equipment for estimating arrival time. The method includes: determining a route to be estimated; obtaining a feature set of the route, and the feature set includes: The road section feature of the road section, the road section sequence includes at least one road section, and the road section feature is a feature that affects the travel time of the road section; the road section characteristics of each road section in the road section sequence are input into the first estimation model to obtain the first estimation model For the predicted first estimated arrival time of the route, the first estimated model is obtained through training using feature sets corresponding to multiple route samples and the actual arrival time. The solution of the present application is beneficial to improving the accuracy of the estimated time of arrival.

Description

technical field [0001] The present application relates to the technical field of map application, and in particular to a method, device and computer equipment for estimating arrival time. Background technique [0002] The estimated arrival time (arrival duration) refers to, for a given route, the estimated time required to reach the end point of the route from the starting point of the route. [0003] The estimation of the arrival time can be applied to various scenarios. For example, in a navigation application, it is necessary to estimate the arrival time of all candidate routes based on the user's starting point and destination, so as to provide the shortest time-consuming route or provide a basis for the user to choose a route; For another example, in the food delivery platform, the total time required for delivery by the rider is calculated based on the location of the customer, the location of the store, and the location of the rider corresponding to the delivery order...
