SUPER ELEVATION SLOPE SHOWING BOTH SIDE TOWARDS CROWN

[surajpanayath]

HI 

Superelevation slope not showing as per my requirement, My requirement is single side slope with superelevation  I am using undivided planar road superelevation. 

Slope direction in subassembly properties I provided away from the crown, but Superelevation slopes show both RHS & LHS sides towards the crown point, please guide me to provide proper superelevation.

The attached image is Civil 3d calculated super elevation details, But my requirement is a manual input method.

see the attached screenshot for references.

Hi @surajpanayath. When working with superelevation values for the "inside" part, you have to be pretty careful about understanding the axis of rotation of your superelevation to assign the right values in the right fields. If your intention is to keep using the "inside," I recommend you to read this:

1. About Superelevation Axis of Rotation Warnings

2. About Superelevation on Divided Roads

If not, a simpler solution would be to use "outside" options (With this lane subassembly: LaneOutsideSuperMultiLayer), "Right Outside and Left Outside". Assign your manual values again to Right Outside and Left Outside, and everything will look as expected.

I hope this helps. Best regards!

Thank you so much for your help.

I used the LaneOutsideSuperMultiLayer option as per your suggestion, it is working as per my requirement.

Hi surajpanayath,

If I can see well in your attached picture your both side of subassembly superelevation set to Right Lane Inside.

According your supereleation slope Right lane Inside has +4% and from this reason both side has positive slope.

Try to change left side of subassembly to Left lane Inside and I hope that issue will disappear.
