How to create custom curve widening?
I'm wondering if anyone out there has used a non-AASHTO curve widening formula to calculate automatic curve widening for an alignment? I'm trying to use our Agency curve widening formula which is a function of curve radius and central angle.
I'm not sure if it is even possible in C3D to use the central angle of the curve for calculating widening, or how one would go about using a non-AASHTO CW formula. Does anyone have any thoughts here?
Attached is the curve widening formula that needs to be used. L will be a constant here.
