Custom Automatic Curve Widening Quesition

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 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.

 

Thanks in advance

50 people have viewed your post. I think anyone had one so far they would have posted. You might try posting in the Civil 3D customization group. Someone there may have a suggestion.
