Hello there,
I would like to ask about Design Criteria Editor (.dvb file) if someone can modify on this file (if it is exist) because i want to add(maximum relative gradient at specified speed).
My superelevation equation (Transition Length) is coming from AASHTO 2001 so we have to take in our consideration the (maximum relative gradient) and as i know till this time, i have to open .XML file and write the (maximum relative gradient value) each time i changed the design speed.
Hopefully i can get an advice and help for this issue.
Thank you.
