Abstract: Travel assistance devices and programs obtain a captured image that captures a surrounding environment of a mobile unit and obtain, as a map information image, a map image that three-dimensionally represents a map and that represents a same range as an image capturing range of the captured image from a same direction as an image capturing direction of the captured image. The devices and programs extract a risk factor based on learning data by inputting the captured image and the map information image to machine learning as input images with a plurality of channels. The risk factor is present in the surrounding environment of the mobile unit and is not included in the captured image.

Abstract: Travel assistance devices and programs obtain a captured image that captures a surrounding environment of a vehicle by an imaging device having a start point of a driver's line of sight and an optical axis corresponding to a driver's line-of-sight direction. The devices and programs identify, based on the captured image and map information of an area around the vehicle, a location where a connecting road is present in the captured image. The connecting road is a road connecting to a traveling road of the vehicle at a divergence point present around the vehicle. The devices and programs determine driver's visibility of the connecting road based on a positional relationship between the location of the connecting road and a location of an obstacle present around the vehicle in the captured image and output a result of the determination.
