PROBLEM TO BE SOLVED: To provide a technique for accurately obtaining a cycle in which the aspect of a traffic light changes.SOLUTION: A signal cycle analysis system includes: probe information obtaining means for obtaining probe information indicating, for every period, the behavior of a passerby who has passed through a road section where a traffic light is present at an end point; cyclicity evaluating means for setting a plurality of virtual cycles as cycles in which the aspect of the traffic light changes and evaluating a cyclicity of characteristics of the behavior in the virtual cycles; and signal cycle obtaining means for obtaining the virtual cycles, when the characteristics of the behavior are most cyclic, as a cycle in which the aspect of the traffic light changes.SELECTED DRAWING: Figure 3 |
