1. A traveled link identifying system, comprising:

  • a communication device that receives information representing current positions of probe vehicles, the information acquired from each probe vehicle at predetermined distance intervals or at predetermined time intervals;

    a memory that stores connection relationships between links, the links representing portions of roads within map data; and

    a controller that;

    acquires position information from the communication device;

    detects links traveled by a probe vehicle on the basis of the acquired position information;

    determines, based on the stored connection relationships, whether it is possible to uniquely identify one combination of links connecting the detected traveled links; and

    identifies a path traveled by the probe vehicle as being a path between the detected travel links along the unique combination of links.
