ROUNDABOUTS SUPERELEVATION

I'm trying to create the superelevation of a roundabout.
I can create the Superelevation Section and Lanes.
But I can´t edit, import or assign the superelevation section because it´s not visible.
Any suggestions?
Thanks.
  • I have checked that here and have noticed the same. It appears to be a fixed setting for that. The superelevation sections/lanes wouldn't have been intended for use with small single elements and was set up for multi element alignments to automatically generate superelevation based on a rules file.

    For what you are intending on doing a rules file will be of no use and you will have to manually set the superelevation which negates the purpose of the superelevation tool.

    From a designer perspective the design process I would use would be as below.

    1. Create the roundabout crown element and edge roundabout circulatory carriageway elements.
    2. Apply a vertical profile to the crown.
    3. Transfer levels to the roundabout circulatory carriageway elements from the crown using Profile by Slope from Element and Profile by Variable Slope From Element at the required values and locations.



  • Hi. I have the same probleme with a roundabout of 12.5 m of radii. I create the superelevation section and lane. But I can't edit or take this section. Therefore, I can't assign this section to its corridor.

    I've seen in the answers that it isn't possible construct a superelevation for little roundabouts. We must proceed with line with variable slope. Is it true? How can I to make a report of superelevation for this roundabout?

    Thanks.
