Abstract

The invention provides a method and a device for determining a route. The method comprises the steps of: determining a plurality of candidate routes by a terminal device according to an origination and a destination; segmenting each candidate route according to the number of maneuver points on each candidate route, and acquiring historical user trajectory information of each segment road on each candidate route from the server; and selecting a target route from a plurality of candidate routes according to a historical user trajectory of each segment road on each candidate route, wherein each segment road on the target route is consistent with the corresponding historical user trajectory information. According to the route determining method, since the historical user trajectory is the route actually used by the user, the bad case in the selected target route is avoided.

Description

technical field [0001] The invention relates to the field of maps and navigation, in particular to a method and device for determining a route. Background technique [0002] Electronic map, also known as digital map, is a map that is stored and viewed digitally using computer technology, and is currently widely used in electronic devices. Before traveling, people can refer to the traffic status displayed on the map and choose a relatively smooth route to avoid congestion. [0003] In electronic navigation applications, a route is planned for the user based on the user's starting point and destination. When planning the route, the following principles are generally followed: the shortest time, the shortest distance, whether to take toll roads, etc. At present, the routes recommended by navigation for users may contain various bad cases (BADCASE), such as partial detours, due to inaccurate data attributes, incomplete road coverage, or immature multi-route algorithms. Frequen...
