Abstract: A traffic signal cycle estimation device 2 is provided, which includes a travel time acquisition unit 4 acquiring a traffic signal section travel time, a frequency distribution calculation unit 5 calculating a frequency distribution of the traffic signal section travel times on the basis of the traffic signal section travel times, a travel time group determination unit 6 determining a first travel time group in which the vehicle does not stop at the traffic signal and a second travel time group in which the vehicle stops at the traffic signal on the basis of the frequency distribution of the traffic signal section travel times, and a traffic signal cycle estimation unit 7 estimating cycle information of the traffic signal on the basis of a difference between the first travel time group and the second travel time group.

Abstract: A traffic signal cycle estimation device 2 is provided, which includes a travel time acquisition unit 4 acquiring a traffic signal section travel time that is a time taken from the entrance of a vehicle into a predetermined traffic signal section that corresponds to a traffic signal until the vehicle passes through the traffic signal section, a frequency distribution calculation unit 5 calculating a frequency distribution of the traffic signal section travel times acquired by the travel time acquisition unit 4 on the basis of the traffic signal section travel times, a travel time group determination unit 6 determining a first travel time group in which the vehicle does not stop at the traffic signal and a second travel time group in which the vehicle stops at the traffic signal on the basis of the frequency distribution of the traffic signal section travel times calculated by the frequency distribution calculation unit 5, and a traffic signal cycle estimation unit 7 estimating cycle information of the traffic
