摘要： A recommended traveling speed provision program according to one aspect of the present disclosure causes a computer to function as: an acquisition unit configured to acquire, from probe vehicles, pieces of probe information each including information of a time within a predetermined time period and a position of the corresponding probe vehicle at the time; a representative traveling speed calculation unit configured to calculate a representative traveling speed that is a representative value of traveling speeds of the probe vehicles, based on the pieces of probe information acquired by the acquisition unit; a recommended traveling speed calculation unit configured to calculate a recommended traveling speed, based on the representative traveling speed calculated by the representative traveling speed calculation unit; and a provision unit configured to provide the recommended traveling speed calculated by the recommended traveling speed calculation unit to a target vehicle.

摘要： A driving safety support system according to one aspect of the present disclosure includes a server, and a safety driving assistant device. The server performs operations including: acquiring, from probe vehicles, probe information including information of a time within a predetermined time period and a position of the corresponding probe vehicle at the time; calculating, based on the probe information, a traffic congestion tail position located upstream of a branch point at which a road branches into a plurality of lanes; and calculating a lane-change recommendation section in which a lane change is recommended based on the traffic congestion tail position. The safety driving assistant device performs operations including executing a driving safety support process for a target vehicle based on the lane-change recommendation section.
