Information processing device and non-transitory storage medium

1 . An information processing device comprising:

a memory; and

a processor coupled to the memory, wherein the processor is configured to:

acquire a captured image, which is captured from above, of a region including a road area, position information for a vehicle that is positioned in the region, and operation information relating to an operation of the vehicle;

use the position information and the operation information to determine a parking area in which the vehicle is parked;

use the parking area to identify the road area included in the captured image, extract vehicles present in the road area, and estimate a traffic volume in the road area;

generate an estimation model using learning data that is selected and generated by a user;

estimate, by performing machine learning using the estimation model, the traffic volume using captured images, captured in the past; and

output the traffic volume of the road area included in the acquired captured image, with an estimation result by the processor and the acquired captured image as inputs.

2 . The information processing device according to claim 1 , wherein the processor is configured to:

acquire the position information and the operation information from the vehicles, which are running, and in a case in which there is a period of time in which the position information and the operation information cannot be acquired and the position information before and after the period of time indicate a same position, determine that a position indicated by the position information is the parking area.

3 . The information processing device according to claim 1 , wherein the operation information includes at least one of a state of a vehicle shift range, a vehicle speed, or a vehicle steering angle.

4 . An information processing system comprising:

the information processing device according to claim 3 , the information processing device including a center server; and

the vehicle including:

an onboard unit comprising a central processing unit,

a position range sensor configured to detect a change of the vehicle shift range, and

a plurality of electronic control units, at least one of which is configured to control the state of the vehicle shift range, wherein

the onboard unit is configured to transmit, to the processor of the information processing device, the operation information including the detected change and the state of the vehicle shift range to determine the parking area.

5 . A non-transitory storage medium storing an information processing program that is executable by a processor to perform processing, the processing comprising:

acquiring a captured image, which is captured from above, of a region including a road area, position information for a vehicle that is positioned in the region, and operation information relating to an operation of the vehicle;

using the position information and the operation information to determine a parking area in which the vehicle is parked;

using the parking area to identify the road area included in the captured image, extract vehicles present in the road area, and estimate a traffic volume in the road area;

generating an estimation model using learning data that is selected and generated by a user;

estimating, by performing machine learning using the estimation model, the traffic volume using captured images, captured in the past; and

output the traffic volume of the road area included in the acquired captured image, with an estimation result by the processor and the acquired captured image as inputs.
