Description
This app is a digital version of the Roadside Barrier Index Nomograph from the BC Supplement to TAC, Page 610-3, April 2019 edition, BC Ministry of Transportation, Canada. It allows you to compute the barrier need index without leaving the Autodesk® AutoCAD®/Autodesk® Civil 3D® design environment.
Features:
- Instant BWI computation
- Automatic Friction computation from Ball Bank indicator reading or Curve Design Data
- Automatic Effective Height of Fill Computation from input parameters (organized by type)
- Value interpolation within the parameter min/max range (except for the Climatic Conditions parameter)
- Parameter range checks and validation
- Critical values computations for all input parameters (except Climate), if within the allowed range
- Native AutoCAD Palette GUI interface
Interpolation is based on the n-degree polynomial best-fit approximation for all parameters except Fill Slope, which is interpolated linearly from the nearest discrete values
