1. An information processing device that provides a travel route to a destination to an occupant of a first vehicle, the device comprising:
a controller configured to:
acquire travel information obtained by a second vehicle that travels on a candidate route to the destination set by the occupant from a second point in time prior to a first point in time when the destination is set by the occupant of the first vehicle, the travel information including first operation information on a windshield wiper of the second vehicle,
estimate weather information on the candidate route on which the second vehicle travels based on the first operation information on the windshield wiper of the second vehicle, the estimated weather information including information on precipitation and information on humidity, the first operation information on the windshield wiper of the second vehicle having been acquired by the controller from a source external to the information processing device,
decide an optimal travel route for driving of the first vehicle to the destination based on the acquired travel information and the estimated weather information, and
in a case where the candidate route on which the second vehicle travels is decided as the optimal travel route, decide an operation mode of air conditioning in a vehicle cabin of the first vehicle when the first vehicle travels on the optimal travel route based on the information on the humidity that is estimated based upon the acquired first operation information that is obtained by the second vehicle, wherein
the first vehicle is configured to autonomously control itself based upon the optimal travel route and the decided operation mode of the air conditioning,
the controller is configured to decide the optimal travel route as a route with more precipitation,
the travel information includes second operation information on hazard lights of the second vehicle including a length of time in which the hazard lights remain on, and
the controller is configured to:
estimate parking and stopping information including whether the second vehicle is parked on the candidate route and whether the second vehicle is parked and stopped on the candidate route based on the acquired second operation information,
decide the optimal travel route based on the estimated parking and stopping information,
in the case where the candidate route on which the second vehicle travels is decided as the optimal travel route, the controller decides driving information of the first vehicle, including which of a left lane and a right lane to travel in, when the first vehicle travels on the optimal travel route based on the estimated parking and stopping information, and
determine the second point in time such that an amount of travel information acquired by the second vehicle from the second point in time to the first point in time is equal to or greater than a predetermined threshold value, the predetermined threshold including an amount of travel information needed when the controller decides the optimal travel route by using the travel information acquired by the second vehicle.
