No cross traffic is the thinking, so the most dangerous situation - someone blowing through the stop sign at full speed - is less likely to be an issue, because it can only happen in on the road that's the top of the T, and since bottom of the T traffic always needs to stop, they are more likely to notice traffic that may blow through the sign.

If you look at modern American suburban streets, you'll see this idea in action. Most intersections are 3-way vs the grid layout common in older areas.

Maybe I haven't seen 'modern' suburban streets, because all the suburbs I know have 4 way stops

So they're asking for a redesign with 3-way intersections, not some weird setup where you remove one stop sign?

Because the mentality is to stop, look, and wait for it to be clear, rather than stop and immediately just go.

Stop and immediately go is particularly a problem for less visible road users like pedestrians and cyclists.

Not sure how that would work where I am from… there are so many cars, the one direction that didn’t have the stop sign would be constantly full and the other three directions would just sit there.

An intersection that busy should just be a traffic light though. All of these other measures are for managing flow at intersections where natural gaps exist and can be leveraged.

Or the speed reduced - you can handle a lot of traffic at an unsignaled intersection of both roads are slow enough.

It’s when there’s a huge speed differential and no signaling that it becomes a problem as traffic gets higher.

These are in residential neighborhoods, and stop signs help prevent people from speeding, as well.
