1. An object path prediction method for predicting paths of a plurality of objects by a computer having a storage unit that stores at least positions of the plurality of objects and an internal state including a speed of each object, comprising:

  • a trajectory generation step of generating a trajectory in a space-time constituted by time and space from changes of the position that can be taken by each of the plurality of objects with a passage of time based on, after reading the positions and the internal states of the plurality of objects from the storage unit, the read positions and the internal states of the objects;

    a prediction step of probabilistically predicting the paths of the plurality of objects by using the trajectories generated in the trajectory generation step; and

    an interference level calculation step of calculating, based on results of prediction in the prediction step, a level of interference quantitatively showing an extent of interference between the paths that can be taken by a specific object and those that can be taken by other objects.
