Question:

Where are the curve widening tables located?

Answer:

Curve Widening Tables are not delivered with InRoads.  You will need to create your own tables based on AASHTO guidelines and your design criteria. 

The example below shows a widening table file:

Where:

Rad = Radius

Wid = Widening inside of curve

Li = Length of transition inside of curve

Wo = Widening outside of curve

Lo = Length of transition outside of curve
