the information on the parking lot includes positional relationships between the estimated point and a plurality of entrances of the parking lot; and
the controller is configured to select one entrance from among the entrances based on the positional relationships, and include, in the action plan, an action of entering with the vehicle from the selected entrance.
12. The plan proposal device according to claim 1 , wherein:
the prediction result includes an estimated point that the first user is expected to visit with the vehicle after leaving the parking lot with the vehicle;
the information on the parking lot includes positional relationships between the estimated point and a plurality of exits of the parking lot; and
the controller is configured to select one exit from among the exits based on the positional relationships, and include, in the action plan, an action of leaving the selected exit with the vehicle.
13. The plan proposal device according to claim 1 , wherein:
the prediction result includes a predicted action to be taken by the first user after parking the vehicle in the parking lot;
the information on the parking lot includes information on a plurality of parking spaces in the parking lot; and
the controller is configured to select one parking space from among the parking spaces based on the predicted action, and include, in the action plan, an action of parking of the vehicle in the selected parking space.
14. The plan proposal device according to claim 1 , wherein the controller is configured to:
select one entrance from among a plurality of entrances of the parking lot based on congestion statuses of the entrances when a position of the vehicle is included in a reference geographical range;
generate guidance data for providing guidance on a route from the position of the vehicle to the selected entrance; and
output the generated guidance data.
15. The plan proposal device according to claim 1 , wherein the controller is configured to:
select one parking area from among a plurality of parking areas of the parking lot based on congestion statuses of the parking areas when a position of the vehicle is included in a reference geographical range;
generate guidance data for providing guidance on a route from the position of the vehicle to the selected parking area; and
output the generated guidance data.
