    摘要: An in-vehicle device includes first circuitry configured to: detect that a predetermined lane change has been made in a vehicle; acquire information indicating acceleration of the vehicle, the acceleration being an acceleration at a time when the lane change is made; judge a traveling environment of the vehicle, the traveling environment being a traveling environment when the lane change is made; decide a first risk level by comparing the information indicating the acceleration acquired by the first circuitry with one or more first threshold values; and determine a risk level of the lane change using the first risk level decided by the first circuitry and the traveling environment of the vehicle judged by the first circuitry.

    摘要: An information processing system includes a server and a first vehicle acquiring a combination of first and second position information of the first vehicle. The first position information is calculated using a positioning signal from the first satellite system. The second position information is obtained by correcting an error of the first position information using a positioning reinforcement signal from the second satellite system. The first vehicle or the server calculates difference information between the first and second position information for each combination thereof. The server estimates a calculation accuracy for the first position information in a road section on a road map based on one or more pieces of difference information in which one or more positions indicated by the second position information corresponding to the difference information are within the road section and to output the calculation accuracy for the first position information in the road section.
