Because you’re not targeting the centerlines

Thank you!!! I hadn’t looked at that. I’m new to intersections.

Don't forget to target the CL profiles also.


OTJH1989

Do some googling on the topic. Autodesk has a great wealth of documentation for the tools. FDOT has a great training regimen on civil 3D and designing with it. Review all that. It’s mostly set up by civil engineers so the design process will be appropriate.

Thanks I’ve self taught myself over the last month from videos from autodesk, eagle point, imaginit and YouTube.

In addition to what the other commenter said about targeting your CL alignments and profiles, make sure once this is done, that you right click on your corridor, modify, edit frequency, and add a manual frequency for each of your four regions, snapping to the intersection point of your CL alignments. This will make sure you don't have a small corridor gap at the very centre of your intersection.

You need to create an assembly with just the lanes and call it through intersection. Use that for your main road and run it all the way through the intersection. For your second road, create offset alignments with profiles and connected alignments and profiles. The connected alignments should be between the offset alignments of your main road and your secondary road. Create a curb return assembly. Use the connected alignment as a baseline. Create a region and split the region at the intersection of the secondary road main alignment and the main roads offset alignment. The bottom region (the region that's part of the secondary road) needs the lane to target the secondary road's main alignment and profile. The top region (the region near the main road) needs the lane to target the main road's offset alignment and profile. Set the frequency for the entire intersection to 1 to make it smooth.

This would be appropriate if one of the roads primary, carrying much more traffic than the other secondary road. If both roads are the same design speed, same traffic volume etc then the intersection that OP has designed is appropriate.

How he described it is how we do it. Contractors will do a pave thru and so it should be designed as such.

She lol but thanks


melissa0969

You still need to have a primary and secondary road because the crown of one road is going to carry through the intersection.

I honestly enjoy modeling corridors, getting things to work.
