Abstract
A path determination method includes the steps of (a) determining a path in a first region which has a utilization efficiency less than a predetermined value probability-wise, (b) determining a path in a second region which is different from the first region when the utilization efficiency of the first region exceeds a second predetermined value, where the second region has a utilization efficiency exceeding the first predetermined value probability-wise, (c) dividing an entire region which is to be subjected to a path determination into partial regions of predetermined sizes and using the partial regions as a minimum unit of path search, (d) assigning to each of the partial regions a state quantity which is described by a path accommodating capacity within each of the partial regions, and (e) searching a path between two points by controlling a search speed depending on a change in the state quantity between adjacent partial regions.
