A travel link identification system

摘要

A traveled link identifying system is capable of identifying a combination of one or more links as a route traveled by a vehicle between two or more links thereby allowing it to correctly identify the route traveled by the vehicle on the basis of acquired information indicating a vehicle position. Two points passed through by an information probing vehicle are detected from position coordinate information included in probed information transmitted from the information probing vehicle. If a combination of links is uniquely identified as a route between links corresponding to the two respective points, the links of this combination are identified as links traveled by the vehicle.
