Raised Intersections?

Question

I am working with Complete_Street Rule for a model I am building, and I was wondering how to create a ramp-like shape for a raised intersection.

(This street will intersect Pedestrian walkways with a raised brick intersection that cars can cross if need be.  When street meets intersection, there is a small concrete ramp that rises from street level to intersection level. I tried to use the "envelope" command in the rule file to raise the "Crosswalk" rule as the ramp, but that only works for one side of the intersection while the other three all taper the same way (not towards the intersection).  Any idea how to tell each crosswalk (all 4 incoming street segments) to taper towards the intersection?

Hey Micah,

I will investigate some too. I should have taken a look at this a while ago. I think part of the problem is that the envelope function can do some weird things when it is not aligned properly. Crosswalks are not the ideal shapes to potentially be using them on.

Also if you want some guidance on design, I deferred to NACTO for mine. Their guidance on vertical control elements is pretty relevant. I deferred to speed tables for my raised intersection design.

Keep me posted,

David

Thanks! I will investigate more and keep you posted.  Your right, it is frustrating because its so close to working.  The roof shed idea might be the answer. I did not think about that.

Also, something that might help is trying to see if there is any pattern between the edge numbers and the ConnectionStart and ConnectionEnd Parameters. I have a sneaking suspicion that might be a way to align yourself, but again I have not checked...only gut feeling.
