Embodiments of the present invention provide an information acquisition method and device. On the one hand, the embodiment of the present invention uses a time-based calculation model to obtain the estimated arrival time of each vehicle driving road and each vehicle driving road between the starting place and the destination according to the starting place and the destination; At the time at both ends, the actual arrival time of each vehicle's driving road is obtained; thus, the vehicle driving road whose difference between the estimated arrival time and the actual arrival time meets the preset conditions is obtained as a candidate road; furthermore, the candidate road is removed The candidate roads with abnormal actual arrival time, the candidate roads with abnormal real-time average travel speed and the candidate roads with abnormal historical average travel speed are used to obtain the target road. The embodiments of the present invention are used to solve the problem in the prior art that roads with updated road feature attributes cannot be obtained.
Description
【Technical field】 [0001] The present invention relates to the technical field of Internet applications, in particular to an information acquisition method and device. 【Background technique】 [0002] Map data is the basis of map services and applications. If there is an error in the map data, it will affect the performance of the map algorithm, which will reduce the accuracy of the output data of map services and applications, and lead to bad cases. Therefore, timely and accurate update of map data is the basic work of map services and applications. In practical applications, map update information needs to be collected, and then operation and maintenance personnel need to update the basic road network data according to the map update information, and the map update speed is fast. [0003] In the prior art, there are two ways to collect map update information, one is to obtain map update information from information publicly released by official departments, such as expressw...
