Abstract
An object is to provide a travel environment analysis apparatus that accurately estimates an event occurring outside of a vehicle. A travel environment analysis apparatus includes a gaze point concentration area detector, a gaze point concentration area event estimation unit, and an information output unit. The gaze point concentration area detector sequentially detects a gaze point concentration area that is an area outside of a plurality of vehicles and gazed by occupants of the plurality of vehicles, based on line-of-sight information related to lines of sight of the occupants. The gaze point concentration area event estimation unit estimates, when a new gaze point concentration area which is a gaze point concentration area newly coming up is detected, an event occurring in the new gaze point concentration area. The information output unit outputs information of the new gaze point concentration area and information of the event.
