Abstract: A method of updating map data, an electronic device, and a storage medium, which relate to a field of computer technology, and in particular to intelligent transportation technology. The method of updating map data includes: acquiring a traffic event text, where the traffic event text includes location data and reference direction data; determining candidate road data in the map data based on the location data; determining target road data from the candidate road data based on the reference direction data; updating the target road data based on the traffic event text.
