Here is my attempt to propose some Ring design concepts and to start the discussion of the pros and cons for each. You can vote for your preferred choice in the poll and please leave any comments you have.
I have taken a typical section of the Ring (Burgring - Opernring) that illustrates the kind of side street and 3 lane pedestrian configuration that is common. I am only attempting to illustrate the basic concept here not the detail of each junction or section.
Option 1: Current design.
Option 3: Cycle path on the side streets.
Option 4: A bidirectional cycle path on the main road.
Option 6: Integration of bicycle traffic with traffic reduced and calmed side roads.
Option 7: Car free zone (like the Prater Hauptallee).
