TRAFFIC LANE ESTIMATION DEVICE AND TRAFFIC LANE ESTIMATION METHOD

WIPO Patent Application WO/2021/235209

A1

A traffic lane estimation device (101) determines whether the accuracy of positioning is greater than or equal to a predetermined value on the basis of accuracy information. If the accuracy of positioning is determined to be greater than or equal to the predetermined value, the traffic lane estimation device identifies a traveling traffic lane on the basis of position information and road map information. Thereafter, if the accuracy of positioning is determined to be less than the predetermined value, the traffic lane estimation device determines, on the basis of travel information and road surface profile information contained in the road map information, if there is traffic lane change from the traveling traffic lane identified when the accuracy of positioning was determined to be greater than or equal to the predetermined value, and identifies the traveling traffic lane in accordance with the result of the determination.
