1. A moving body position detection system comprising:

  • a dead reckoning navigation information acquisition unit that acquires dead reckoning navigation information on a moving body;

    a position identification unit that identifies a position of the moving body on a link based on the dead reckoning navigation information on the moving body;

    a link data acquisition unit that acquires current position link data on a current position link and neighboring link data on a neighboring link, the current position link being a link on which the position of the moving body identified by the position identification unit is located, the neighboring link connected to the current position link;

    a comparison unit that compares the dead reckoning navigation information on the moving body with the current position link data and with the neighboring link data; and

    a position update unit that updates the position of the moving body, identified by the position identification unit, based on a comparison result of the comparison unit,wherein;

    the dead reckoning navigation information includes information on a direction of the moving body;

    the link data acquisition unit acquires a direction of the current position link and a direction of the neighboring link; and

    the comparison unit compares the direction of the moving body with the direction of the current position link and with the direction of the neighboring link.
