Superel transitions for compound curves
Superel transitions for compound curves
(OP)
Most of my experience has been in traffic safey and operations, but now I'm involved in designing a rehab project for a rural highway. This is a moderately low volume rural collector. The traffic volumes don't justify the expense of realigning curves.
When dealing with compound curves on rural highways, how does one transition the banking from one curve to another? I didn't find the 2005 Green Book to be very helpful.
Thanks!

Were you dealing with opposing curves? I should have specified that all but one of the compound curves are in the same direction. Should I put 1/3 of the transition on the sharper curve, and 2/3 on the wider curve?
Opposite direction compounds are in a sense easier since there isn't much else you could do.
