Corridor transitions

[Anonymous]

How would one go about creating a transition from a 2 lane roadway assembly
to a four lane roadway assembly?

[Anonymous]

the use of transition alignments does not work? Can I see a screen capture
of you plan?

For now it is hypothetical. At the beginning of the transition the added
lanes are compressed down to zero width and I'm not sure how it would work.
I was watching a webcast on Bentley's roadway designer which handles it
parametrically so I am trying to get a comparison.

but the transition alignment would work?

The paremetric setting for the Bently product did not have to use a similar
edge line to follow?

In the Bentley product you graphically link the point codes between the 2
assemblies in a special 3D view and the transition strings will stretch or
contract according to the end stations of the transitions. I haven't tried
it in C3D. I'm hoping there are some InRoads users here who might be able to
give a better understanding on how it compares.

If it's a straight linear change over some distance, I'd simply leave a
gap in the corridor and let the FLs handle the transition. Relative
codes will connect, and you'll have a nice transition. If you want to
have a reverse curve, or want to do it over a longer transitional period
than a gap is acceptable, you'll have to put in some alignments and have
the lanes go from 0 width to full width as you've described. Collapsing
a lane to 0 is a trick I use all the time in Curb Returns, so it should
not be a problem here either.

I went through a test and it works as you said James. Thanks
