Abstract
A road segment set influenced by an event on the basis of a connected network is identified. The connected network is built on the basis of reachability of a road segment in the road network. Furthermore, each road segment in the road segment set is reachable via the road network from the location of the event, or, in the alternative, the location of the event is reachable via the road network from each road segment in the road segment set. A query index is generated on the basis of the event and the road segment set.
