Alignment Superelevation Calculations - Transition Length vs Spiral Length

[LeafRiders]

For those familiar with Alignments and Design Standards files related directly to superelevation calculations and including spiral lengths and transition lengths, this is a topic for you! 

The situation I have is that while I've created a clear Design Standards file based on my jurisdiction. Once I calculate the superelevation I was hoping to see the transition lengths that are standard applied to the superelevation calculations after the wizard does it's things. Now for whatever all the key stations that are assigned by Civil 3D default are all set to be the Start and End of the spiral-in and spiral-out. Why, I have no idea since this should be based on the transition length. 

I'm pretty sure this isn't how road / highway design is supposed to be intended since we apparently need to adjust all the key stations in superelevation tables to match what is "required" based on the standard transition length. If a spiral is set to 100m and the transition standard is set at 190m. The transition in and out regions should be based on the transition length and NOT the spiral length.

I'm hoping I'm missing a setting and that Civil 3D isn't built this way by accident. I'm fairly supprised the highway designers haven't come across this and posted anything within the Autodesk Community. Any assistance on procedure changes to get this to work "properly" would be greatly appreciated.

Hi.

I made my own app:

https://apps.autodesk.com/CIV3D/es/Detail/Index?id=9143282069119286222&appLang=es&os=Win32_64

To calculate superlevations and apply transition lengths properly because the Spanish XML file was incorrect about this.

My app calculate manual superelevation critical stations and remove the previous ones.

Unfortunately I am not up on my spanish. However, the screenshots of the app and the criteria it deals with looks like something that would help. Thanks for sharing.

Furthermore, I'm looking into the attainment methods further and this is likely the area that needs to be refined in order to adjust this. If I fully resolve this problem I'll post my findings here.

In summary, once you select your alignment the Ribbon shows "Design Criteria Editor". In here you can alter any of the attainment methods and set the particulars. Unfortunately once you make edits and you open the file in NotePad the portion that is edited isn't kept all tidy like the information that was coded for the OTB design standards files. The sky is limit for how you want to set up the Design Criteria / Standards file. Use this as your standards checking and avoid the duplicate "Design Checks" portion of things to avoid complicating things.
