Abstract

The embodiment of the invention provides an information acquisition method and device. The information acquisition method comprises the steps of obtaining vehicle driving roads of between a starting place and a destination and the predicted arrival time of each vehicle driving road based on a time calculation model, obtaining the actual arrival time of each vehicle driving road according to the time when the vehicle arrives at the two ends of each vehicle driving road, so as to obtain the vehicle driving roads with the difference between the predicted arrival time and the actual arrival time meeting the preset condition; removing candidate roads with abnormal actual arrival time, candidate road with abnormal real-time average driving speed and candidate roads with an abnormal historical average driving speed, and obtaining a target road. The problem that in the prior art, the road with updated road feature attributes can not be obtained can be solved.

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...
