Signal machine cycle estimator and signal machine cycle estimation method

摘要

Signal cycle estimation apparatus according to the present invention (2), travel time acquisition unit for acquiring a signal section travel time which is the time until the vehicle to traverse from entering the signal a predetermined interval corresponding to the signal (4) , often as calculated frequency distribution calculating unit based on the signal section travel time obtained travel time acquisition section (4), calculates the frequency distribution of the signal section travel time and (5), the frequency distribution calculation unit (5) travel time group determination unit for determining the travel time a second group on the basis of the distribution, the vehicle travel time first group of the vehicle is not stopped at the traffic signal is stopped at traffic lights (6) travel of the first and a signal cycle estimating unit on the basis of the difference between the travel time of the second group and the group time, estimates the signal cycle information of the machine, and (7).
