How to derive superelevation information from an imported elevation map in RoadRunner?

We import an orthophoto and an elevation map into RoadRunner. We create a map manually using the orthophoto as guidance. We use RoadRunner to project the map onto the elevation map such that the exported map contains the correct elevation profile. The problem is that we also need the correct superelevation profile and we wonder if RoadRunner has a functionality to automatically derive this superelevation profile as well from the imported elevation map?

If you imported the elevation map, you can do the following:

1) Choose the Road Plan Tool and create a road that runs over the elevations.

2) Then select the Project Roads Tool on the left-hand side to get the slope.

3) Now, if you want to get the banking, select the Cross Section Tool, click via right into the road and choose the option "Project Cross Section" inside the 3D Editor.

4) You can repeat point 3 and everything in-between gets interpolated. This enables to follow the slope as well as the banking projection.
