Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0048]The existing navigation route calculation method sets the same steering cost for the same type of steering relationship at different intersections when searching for a navigation route. Set turn cost x2, etc. This method cannot effectively avoid frequently congested intersections in the process of searching for navigation routes.

[0049] see figure 2 An example situation is described:

[0050] The navigation route planning request includes a starting point O1 and an endin...

Abstract

The invention discloses a navigation route determination method and device. The method includes: searching a navigation route from a starting point to a terminal, if the navigation route includes an entry road and an exit road of a crossroad, and the steering relationship composed by the entry road and the exit road is marked with a steering punishment label, determining the steering punishment cost of the steering relationship while passing the crossroad according to the real-time traffic state of road contained in the steering relationship; and according to the passage cost of the road contained in the navigation route and the steering punishment cost of the steering relationship, acquiring the passage cost of each navigation route, and selecting an optimal navigation route for output according to the passage cost of each navigation route. According to the invention, through the steering punishment cost, the passage cost of navigation route containing corresponding steering relationship is punished, the purpose of avoiding selection of the navigation route while selecting an optimal navigation route can be achieved, therefore the navigation route finally provided to a user can bring better navigation experience to the user.

Description

technical field [0001] The present application relates to the technical field of navigation, and more specifically, to a method and device for determining a navigation route. Background technique [0002] With the improvement of people's living standards, cars have been widely popularized, which greatly improves the convenience of users' travel. However, the ensuing problem is that road congestion has become more and more serious. Especially during rush hours, traffic jams have become inevitable. [0003] For some intersections in urban roads, due to the design defect of the intersection or the traffic flow is particularly large, one or more steering relationships of the intersection often have congestion, and once the congestion occurs, it is particularly difficult to alleviate. The steering relationship consists of an incoming road and an outgoing road at the intersection. see figure 1 As shown, at the intersection C1, one entry road is R1, and there may be multiple ex...
