Ensuring faster and smoother transit of road-based public transport vehicles (buses, trolleybuses, etc.) is possible by active prioritizing of these vehicles at signalized intersections.

The most important feature of turbo-roundabouts is a spiral course of the circulatory carriageway allowing drivers easily pass through the roundabout from the entry пїЅ circulatory carriageway пїЅ to the exit without a need to change traffic lanes.
