Embodiment approach

[0085] In another embodiment of the present invention, an optional implementation manner of the above-mentioned step 202 is further introduced, and the process includes:

[0086] Scan from the current segmentation point to the end point of the road section, and use the position where the curvature of the road section is greater than the preset change threshold as the next segmentation point to segment the road section; and / or, from The current segmentation point scans toward the end point of the road segment, and the position where the length of the road segment is equal to the preset length threshold is used as the next segmentation point to segment the road segment.

[0087] Among them, in the case of only dividing according to the length, if the preset length threshold is the total length of the road section / the number of section bars, then the equal division of the road section can be realized; if the preset length threshold is not the total length of the road section / the n...

Abstract

The invention discloses a road traffic condition verification method and device, relates to the technical field of traffic, and can solve the problem of low road traffic condition verification accuracy in the prior art. The method comprises the steps of determining a road section of a to-be-verified traffic condition; constructing a buffer area for the road section according to the positioning accuracy of the road section; and when the number of the tracks of the user tracks passing through the buffer area is greater than a preset number threshold, determining that the road section is passable. The method and the device are mainly suitable for a scene of carrying out validity verification on the traffic condition event reported by the user.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to a method and device for verifying road traffic conditions. Background technique [0002] With the development of computer technology, the functions of electronic map software are becoming more and more abundant. Electronic map software can not only provide users with functions such as map query and navigation, but also receive traffic status events (such as road closures, accidents, construction, etc.) These traffic condition events update the electronic map software. For example, when it is determined that a certain road section is closed, the server needs to recalculate the navigation route, so as to avoid road closures in the navigation route and cause inconvenience to users. [0003] However, the traffic status events reported by users are not necessarily in line with reality, and there may be false reports. Therefore, after receiving these traffic status events, the server ...
