There should be no need to do any "lane mathematics". It's already done for you. If there's an issue with "lane mathematics", then it's probably because you aren't using Network Extensions 2. The only thing you should need to configure after plopping this intersection are the lane assignments using TM:PE. Which I've shown in the images.

Regarding node spacing, that should not be an issue, either. If you set up everything the way I show in the images, then the path finding AI will recognize that a vehicle will need to be in a specific lane before entering the turbine. If you're still having issues with traffic taking strange routes, then double check to make sure you have everything set up correctly, and then check on the rest of your road network. Nine times out of ten, there will be something you missed that's causing traffic to be routed in an undesirable manner.

Otherwise, I've done all I can to make this workable. If you're having issues, then it's not my fault.

I often adapt my donwloaded interchenges to use lane methematics. So, in the end I just use my "own" interchanges, based on the Workshop content.

this is one of the best small turbines. but you have to do lane mathematics and move some roads so there are a little more distace between some nodes. and the roads should be vanilla.. to be usefull. as it is , it is not usefull. but mingle a little, and it works. i always wonder, when the cunstructor dont do lane mathematics..

This looks interesting, thanks!
