Road network is important and indispensable infrastructure as transportation service for modern society. While years after the construction have passed and increase of the aged generation have become to demand how to maintain road surface profile in good conditions for comfortable and safe traffic, and for friendly environment. A new measurement method called sequential-two-angles is proposed, which could be even manually operable to identify the road profile along the device proceeds. The apparatus consists of three rollers, two of which at the outsides are connected in the middle by bars. The height differences of the middle roller to those at the outsides are possible to detect the profile by angle initiates for the first bar and the angle between two bars in terms of encoder attached at the middle. If the procedure is sequentially continued as the device proceeds, the road profile could be successively obtained like similar procedure obtained by auto-collimator. It was made obvious that the method basically works well and how to deal with accumulation of the errors through the analyses and the experiments.
