A first onboard device-mounted on a measuring vehicle—includes a LiDAR, and it receives a reflected wave which is laser emitted to and reflected by a road surface and recognizes a curve start location of a lane line on the road surface based on reflected wave intensity. The first onboard device-transmits road surface information including the recognized curve start location to a server device via a network. The server device gives information indicating the curve start location to information regarding the lane line in map information based on the road surface information. A second onboard device mounted on a vehicle acquires the information regarding the lane line from the server device and estimates a current location by comparing a curve start location of the lane line recognized by a LiDAR and the information indicating the curve start location of the lane line acquired from the server device.
