1. A computer-implemented method of updating electronic map data, the method comprising:
acquiring a traffic event text, wherein the traffic event text comprises location data and reference direction data, and the traffic event text comprises a traffic dynamic event officially released;
determining candidate road data in the electronic map data based on the location data;
determining target road data from the candidate road data based on the reference direction data; and
updating the target road data based on the traffic event text, to obtain the updated electronic map for navigation,
wherein the determining target road data from the candidate road data based on the reference direction data comprises:
determining target direction data based on the candidate road data; and
determining the candidate road data as the target road data, in response to determining that the target direction data is consistent with the reference direction data, and
wherein the determining target direction data based on the candidate road data comprises:
determining a geographic object from the electronic map data with a direction for the candidate road data as a search direction; and
determining, from attribute data of the geographic object, a first address identification as the target direction data, wherein the first address identification indicates going to a first address by passing the geographic object, and the first address corresponds to the first address identification.
