[ORD] Superelevation Parabolic Eases broken in 2019 R2

Hi all,

We're having an issue with Superelevation eases for Parabolic Transitions (ie. Non-Linear Curve Length) not applying in ORD 2019 R2 using CSV import or tabular input, although displaying perfectly in the Superelevation editor. Measurement of crossfalls after applying superelevation shows that it is only producing a linear transition, although it worked fine in older versions of ORD.

After much checking and trial and error, it only seems to work when using Calculated Superelevation via a Rule file - has anyone found a workaround for this? We can't use a Superelevation Rule file as our transition locations are not in textbook locations due to aquaplaning, proximity to structures, etc. etc.

We have dozens of alignments with superelevation and application of superelevation transition eases is a requirement of our road authority and fundamental to our local road design practices.

Regards,

Mark

  • We are experiencing a similar issue in 2021 R2. The parabolic transition seems to apply, but the calculated location of the break point isn't consistent with what actually ends up in the model once applied. Removing the parabolic transition and going to a linear point solves the problem, so we know the superelevation itself is correct. 

    Is this still a defect?
