Hello Everyone,
I would like to know how to calculate superelevation on Undivided Planar Roads, see Figure. I have tried the different methods available but I have not achieved the result I need.
Thank you very much.
Best regards,
Mauro Vega
I recommend watching the Superelevation training video series here: https://learn.bentley.com/app/VideoPlayer/LinkToIndividualCourse?LearningPathID=110831&CourseId=124633&MediaID=5016123. It walks through how to create Superelevation and provides a dataset where you can follow along with the videos.

Hello, Holly
I reviewed the superelevation training videos.
The videos show the steps for the creation of superelevation and the different editing methods, but in the videos they do not show a case similar to the one I have.
I have only one alignment with the following configuration:
- Two lanes 3.65 m each.- Normal crown: -2% for the right lane and +2% for the left lane (Planar Road), see figure:
I build the lanes and I calculate the superelevacion with "Crown" pivot method and the superelevation has errors, see figure.
So, I changed the pivot method to the "Centerline" and the errors in the superelevation continue, see figure.
In both cases the superelevation of the right lane is superimposed with the superelevation of the left lane.
Can anybody help me?
Regards,
If you use the Crown pivot method, you would want both your left lane and right lane normal cross slopes to be -2.00%. I did this, and it looks like this:
Thanks for your response, you are very kind.
I have asked many questions these days. Excuse me.
I do not know what I'm doing wrong, but if I create a right lane with normal crown -2.00% and a left lane with a normal crown of -2.00% the cross section is as shown in the following figure.
Now, if I create a right lane with a normal crown -2.00% and a left lane with a normal crown of + 2.00% the cross section is as shown in the following figure.
The result does not change.
Thanks for your help.
There were a lot of bugs in update 3 version with superelevation. Particularly with how you are defining the normal crown cross slope (I went through the same exercise). I believe this has been fixed in 2018R2 (update 4 new release lingo).

Hello Marc B
I updated ORD to version 10.04.00.48, and the results are the same.
I do not know what to do.
Do you have any suggestion?
