Abstract
This disclosure relates to a traffic information estimation device and a traffic information estimation method for estimating a time period of switching of a traffic signal display. The traffic information estimation device includes: an acquisition unit (203) acquiring arrangement information indicating an arrangement of vehicles in accordance with a time passage on a road on which a traffic signal is installed; a determination unit (205) determining changes in density of the vehicles by using the arrangement information; and a calculation unit (206) calculating a display change cycle indicating a time period of switching of a display of the traffic signal based on a time interval between the changes in density of the vehicles. According to such a configuration, it is possible to simplify processing to estimate of a change cycle of the traffic signal.
