ABSTRACT:
A system for responding to telephone queries for transit system information is disclosed in which the information received by transit information operators is used to initiate a pathfinding query, which results in a search using a heuristic method with Island Sets being performed in order to determine, for example, an itinerary which the operator can relate to the caller which answers the caller's query. A stopping rule, based on clock time, iteration count, openings of goal nodes, adjustments of goal node labels and the state of the transaction queue is also disclosed.
