Unlock request: Wauwatosa, WI

Please unlock these segments on N Mayfair Rd:

I’m requesting the unlock so that I can update these connecting segments on Capitol Dr - this area of Capitol Dr is not split into two one-way segments/boulevarded like the surrounding area:

Not sure it’s necessary to split Capitol Dr within the intersection. The present arrangement isn’t gorgeous, but is it causing problems? If routing is ok may as well leave it alone.

Ah - okay. I’m new. I thought the goal was to make the map true to life.

Nope, it is KISS. The simpler, the better.

There you go. And those little stubs on either side of the intersection really don’t need to be inserted there (they’re against best practices) BUT again, if it works, there’s no mandate to remove them and inadvertently cause unintended problems.

Thanks bigbear and mapcat! I appreciate your responses.

The ‘formal guidelines’ say: “A road should be split if: A road with a non-drivable surface (of any width) between the directions of travel where there are three or more lanes in each travel direction.”

Am I mis-reading that? Or are you saying it just shouldn’t be split at intersections?

I removed the stubs you mentioned, but like you said, I caused unintended problems because the Mayfair Rd segments are locked and I can’t update the turns. Are you able to fix this? - All turns are allowed at this intersection.

Within the intersection it’s not necessary to have them split (there’s no “median” within the intersection). You can have all of the segments meet at a point (which is especially useful if you need to prohibit u-turns). If you go that route, make sure the angle leading into and away from the junction isn’t too sharp, or the driver will get “keep right” or “turn right” prompts for instructions to keep going straight.

With that said, there’s nothing wrong with just leaving it alone if it’s not causing problems. Or with treating it like there is a median within the intersection (i.e., an intersection that looks like # with four individual junctions). I used to eliminate those on principle, but realized that despite their added complexity, if they’re working, it’s simply better to leave them alone.

I unlocked Mayfair so you can finish it.

You forgot to tell him what we call an intersection that comes all together at one node.

It is a mapcat bowtie. :smiley:

Thanks to both of you! I’ve corrected the turns.

Looks good. Assuming u-turns are ok.

Yep, u-turns are ok.
