Add a alignment element to record its inputs, capacity and governing check.
Learning objectives
- Design horizontal curves
- Design vertical curves
- Check stopping sight distance
Engineering judgment
- Design speed drives every geometric element.
- Sight distance is a safety requirement, not a preference.
