Pedro,
The stationing method seems very odd, usually stationing is at some even interval, with additional stations for PC, PT, intersections and possibly structure locations and others. I do not believe you have been forthcoming with enough information to come to a reasonable conclusion on how to proceed. (as usual)
What you are asking for here could evolve into quite a function, especially since you give no clear direction. Are you looking for profile design with vertical curve design based on K factors etc. There are lots of commercially available programs already developed for just this type of application. Are you also looking to generate this profile off a 2d road center-line, using underlying contours or surface to create existing conditions profile? Why not just ask for automatic x-section profiles based on any number of variables at specified intervals while you are at it.
