Problems solved by technology

However, the traffic time on this remote road with good traffic may actually be greater than the traffic time on a closer road with bad traffic, and the overall traffic congestion on the closer road may not exceed the user's acceptable experience range
It can be seen that the congestion avoidance path determined by the existing congestion avoidance algorithm may not be the optimal path

Embodiment Construction

[0018] The basic idea of ​​the embodiment of the present application is: while calculating the avoiding congestion path, also calculate the path under the condition of not considering the road traffic state, that is, the non-avoiding congestion path, and then judge whether the calculated non-avoiding congestion path is congested (also That is to judge whether the congestion degree of the non-avoiding congestion path is within an acceptable range), if it is determined that the non-avoiding congestion path is not congested, and the traffic time-consuming of the non-avoiding congestion path is less than the traffic time-consuming of avoiding the congestion path, then the The non-congestion avoidance path is provided to the user as a congestion avoidance path. The embodiment of the present application also provides a method for judging whether the non-avoiding congestion path is congested: according to the length of the section of the non-avoiding congestion path that is currently ...

Abstract

The embodiment of the application provides a navigation method and a navigation device, which are used for promoting quality of eluding congestion path. The navigation method includes steps of confirming a non-eluded congestion path and an eluded congestion path from a navigation starting point to a navigation termination according to the received navigation starting point and the navigation termination; judging if the non-eluded congestion path is jammed, and comparing the traffic time consumption of the non-eluded congestion path with the traffic time consumption of the eluded congestion path; if the non-eluded congestion path is not jammed, and the traffic time consumption of the non-eluded congestion path is shorter than that of the eluded congestion path, sending the non-eluded congestion path to a user terminal; if the non-eluded congestion path is jammed, or the traffic time consumption of the non-eluded congestion path is longer than that of the eluded congestion path, sending the eluded congestion path to a user terminal. By applying the embodiment of the application, the method and device provide a path of which congestion degree is acceptable by users and the traffic time consumption is the shortest for users, thereby improving the navigation quality and user experience.

Description

technical field [0001] The present application relates to the technical field of navigation, in particular to a navigation method and device. Background technique [0002] With more and more urban vehicles, road congestion has become the most troublesome problem in urban traffic. To this end, the navigation service has launched a congestion avoidance service based on the current road traffic state, which can provide users with a path to avoid congestion. [0003] The existing congestion avoidance algorithms take road congestion as an important factor when planning routes, and tend to choose roads with better traffic conditions. Since the obtained traffic state of the relatively remote road is usually better than the obtained traffic state of the closer road, in many cases, the optimal path calculated by using the congestion avoidance algorithm is relatively remote. However, the traffic time on this remote road with good traffic may actually be greater than the traffic time...
