Patent ID: 7844398

Claim:
A path risk evaluating apparatus for evaluating risk of a movement path of a mobile device, said path risk evaluating apparatus comprising: a secondary collision likelihood evaluating unit configured to evaluate a likelihood of a first object that has a likelihood of being moved by contact with the mobile device coming into contact with or coming close to a second object, based on a relationship between the movement path of the mobile device indicated in movement path information and positions of objects indicated in position information, the movement path information being information indicating a movement path of the mobile device, and the position information being information indicating positions of objects present in an environment in which the mobile device moves; a risky attribute combination evaluating unit configured to determine a degree of damage in the case where the first object and the second object come into contact with or come close to each other, by referring to information indicating degrees of damage in the case where pairs of the objects come into contact with or come close to each other; and a path evaluating unit configured to evaluate the risk of the movement path for the mobile device, based on a result of the evaluation by said secondary collision likelihood evaluation unit and the degree of damage determined by said risky attribute combination evaluating unit.
