Abstract
A method of querying spatial events in a vehicle network includes receiving, by a processing device, a query condition of a user; in response to reception of the query condition of the user, determining context information of a position where the user locates; and according to the query condition of the user and the context information of the position where the user locates, querying an index table recording correspondence between terminal nodes of roads in a road map and spatial events to obtain spatial events meeting the query condition of the user.
