Four-way stops are common, but they seem inefficient. Maybe they can be improved by people just following different rules.
When an intersection with stop signs has too much traffic, the signs are replaced with traffic lights. Why does that allow more cars through? Because many cars go through before the light changes.
But the same principle could be applied without having a traffic light.
Take a 4-way stop intersection, and paint some lines approximately 3 car lengths away from the intersection on each lane approaching the intersection. Have people treat the intersection as a 4-way stop, but have people who stopped on or in front of the new lines go through the intersection at the same time as the person in front of them, unless someone in front of them makes a left turn.
This should allow for better traffic flow than current 4-way stops.
