<P>PROBLEM TO BE SOLVED: To provide a technique for specifying a cycle when the aspect of a signal changes in a state having the few number of samples. <P>SOLUTION: A signal cycle analysis system acquires a plurality of samples indicating, for every period, a travel time of a vehicle that travels on a road section where a signal is present at an end point, specifies a feature distribution that is distribution corresponding to a change in the aspect of the signal on the basis of a time-series distribution of the travel time indicated by the samples, and acquire a cycle in which the feature distribution appears, as a cycle in which the aspect of the signal changes. <P>COPYRIGHT: (C)2013,JPO&INPIT |
