Abstract:
A link combination extraction unit (24) acquires all the combination of link candidates from among link candidates having an angle with respect to a movement direction of a pedestrian equal to or smaller than a threshold value among link candidates for n walking route networks. The link combination extraction unit (24) acquires all the combinations of link candidates that do not intersect with each other among the acquired combinations of link candidates. The link combination extraction unit (24) acquires all the combinations of link candidates that do not connect to each other among the acquired combinations of link candidates. The link combination extraction unit (24) acquires all the combinations of link candidates that are not on the same straight line among the acquired combinations of link candidates. A candidate determination unit (26) acquires a combination of link candidates closest to position information of a pedestrian when there are a plurality of acquired link candidates.
