Could you post an example (link)? I'd really like to see that as I've never seen it elsewhere (but I haven't been to Denmark ).

This would mean 3 full cloverleafs for Hungary.

M6×M8 isn't yet fully functional.

Awesome! Do you know how old the first one is? (the second one isn't that old, because street view from 2009 shows a simpler intersection)

You should extend this work for all E-road network, which coverages Switzerland and Turkey.

The table above just presents a simplified version of my results. In my full spreadsheet I distinguish between four kinds of '3 loop' interchange, depending on how the non-loop long turn is completed. For instance, in the Netherlands my figures were:

- 3 loop stack (semi-direct ramp goes over the top, making it effectively a three-level interchange): 1
- 3 loop corner (semi-direct ramp 'cuts the corner' leaving interchange at two levels): 0
- 3 loop turbine (turbine style ramp): 7
- 3 loop windmill (windmill style ramp): 0
TOTAL 3 LOOP: 8

Also there is a difference between a "real" cloverleaf with separated collector lanes for all ramps, and simplified cloverleafs where the ramps directly connect to the main carriageways.
I didn't distinguish between C/D lane and non-C/D lane cloverleafs, which in retrospect is the one thing I'd do differently. That said, it makes no difference to the above table, as both are types of cloverleaf and would be grouped together.

E-roads extend to Siberia and Central Asian countries like Kyrgyzstan and Uzbekistan. I'm afraid it would be far too much work!

I did compile numbers for a few non-EU countries before I decided to restrict it to EU. All numbers are for cloverleafs (no other types found):

EFTA members:

Iceland 1
Liechtenstein 0

Non-EFTA members:

Andorra 0
Albania 1
Bosnia and Herzegovina 1
Georgia 1
Kosovo 0
Macedonia 0
Moldova 2
Monaco 0
Montenegro 0
San Marino 0
Vatican City 0

The only European (or European-Asian transcontinental) countries I don't have figures for are Belarus, Norway, Russia, Serbia, Switzerland, Turkey, and Ukraine.

I have now completed Norway and Switzerland, so I can present the 'EU and EFTA' table of results:



One qualifying interchange in Norway is somewhat disappointing.

Switzerland does better, though with an unusual proportion of offside entries and exits - you will not find the likes of this in the design manual!

Where is the stack interchange in Germany located?

I think it's decades old and they pretty much gave up on extending it as was once planned

Does anybody know if such a junction exists in reality (not only EU)?

To some extent only, they are different.

In what way? I only see that in this case the roundabouts are triangular.

The four outer circles (adjacent pairs) are touching each other which is not the case with the five outer circles at Swindon. Thus the island areas are different. But OK one can say that the Swindon roundabout is a bit streched and somehow less complicated.
