PROBLEM TO BE SOLVED: To provide a method that is simple in constitution, low in cost, and a short processing time, and suitable for generating data of road position and road width. SOLUTION: In this road end detection method for detecting a road end position in order to generate map data, a traveling position is detected by a GPS receiver 2 loaded on a vehicle, while traveling a road by the vehicle 1; the surface shape of the traveling road on a detection surface of a laser range finder is detected by the laser range finder 3 loaded on the vehicle; and the surface shape is approximated by straight lines A<SB>1</SB>, B<SB>1</SB>, B<SB>2</SB>, B<SB>3</SB>, C<SB>1</SB>, and an intersection point of approximated straight lines is determined to be the road end.
