Abstract

The invention discloses a verification and upgrading method and system for road information in an electronic map. The verification and upgrading method for the road information in the electronic map comprises the steps of acquiring global positioning system (GPS) trajectory data running on a road segment to be verified, processing the GPS trajectory data, and determining a road running direction corresponding to the GPS trajectory data; seeking a time point where road information changes and marking a road segment where the road information changes by employing a time interval differential method according to the processed GPS trajectory data; and performing differential comparison on the GPS trajectory data of the marked road segment where the road information changes and an electronic map database to acquire a data matching result, and modifying the electronic map according to the data matching result. Therefore, with the verification and upgrading method disclosed by the embodiment of the invention, the road driving direction can be rapidly acquired, the electronic map upgrading speed is increased, the data freshness is improved, and resources are saved.

Description

Technical field [0001] The invention relates to the field of map making, in particular to a method and system for verifying and updating road information in an electronic map. Background technique [0002] For some roads, in order to relieve the traffic pressure in a certain driving direction during the rush hour, the traffic rules of these roads can be adjusted, and some road traffic restrictions can be implemented, for example: set it in a certain time period and other time The normal driving directions are not consistent. [0003] At present, in the process of making electronic maps, the way of collecting road information for a specific time period is still to be collected by the field industry according to the collection plan. When verifying data operations, the following verification methods are usually used for the information collected on the field: [0004] Method 1: Default information collected in the field is correct. However, using this method of acquiescing that all t...
