For Crest curve stopping sight distance, we set our eye 3.5' above the road, and we set our target 2' above the road.
For Sag curve stopping sight distance, we set our headlight 2' above the road aimed upward at 1°, and we set our target on the ground.
It would appear that the Roadway Visibility tool in IR SS2 only does that first calculation. Is there any tool that can generate similar sight lines for the second calculation?
I'm actually still trying to figure out what the output is for this tool. All it gives me is plan view data - I was hoping for profile-based information so I could generate documentation illustrating lines of sight along the profile. Is there another tool that can generate that, or have I just not found the right settings?
Another instance where Help is not very helpful...
Thank you
