Hi all,
I was trying to create a 3 legged roundabout in ORD using Stockdale principle. All the legs of the Roundabout are 4 lane divided carriageways. I am attaching a screenshot of the layout done using Horizontal Alignment tools in ORD. Can you review the layout and advise me on how to proceed with profile design of the crown line and the arcs connecting the crown line with median edge of each leg? Any videos or tutorials on 3 legged roundabout Stockdale design would be really helpful.
Chris - do an internet search on "stockdale method roundabout design pdf" and (for me) the first result explains the theory - from original article too. It is basically a way to tie the vertical profiles together.
