SIDE ROAD INTERSECTION AND SUPERELEVATION
SIDE ROAD INTERSECTION AND SUPERELEVATION
(OP)
What is the accepted procedure for dealing with the superelevation transition on a side road tying into a main line alignment when the main line profile is steep and the side road has a curve that produces a superelevation in the opposite direction? The intersection is a stop condition on the side road. Do you use full super on the side road curve and if so do you use the same rate of change that you used to get into the curve to also get out and match the adverse main line profile grade. The PT of the curve is close to the edge of pavement and there is not much room for transition. Is there a reference that covers this type situation out there? This situation is hard to describe so if you don’t understand I will be glad email you a sketch.

Of coourse, depending on the existing crash history, and the cost of right of way, you may not be able to justify the expense.
