I had littel response in the traffic forum, so I thought I'd try here.
NYSDOT used to have a template for checking whether vehicles would bottom out at driveway or intersection entrances, but it appears to have been deleted.
A consultant designing a road reconstruction project is proposing an intersection with a 7.5% crest change of grade w/o a vertical curve (uphill approach on the outside of a superelevated curve), and another with a 13% sag change of grade (downhill approach on the inside of a superelevated curve).
I suspect vehicles will be scarring our beautiful new pavement, but need help proving it. Any suggestions?
