CFVR5131 - Bridge model creation
The example is a bridge with the follow geometry:
Plan View
- Straight line: From MP 90 to MP 120.
- Clothoid: From MP 120 (radius = 0) to MP 170 (radius = -200).
- Arc: From MP 170 to MP 200 (radius = -200).
- Parabola: From MP 90 (0% slope) to MP 200 (5% slope).
The aim of the example is to verify the geometry of a bridge.
