Differences in speed cause an accordion effect (https://en.wikipedia.org/wiki/Accordion_effect), which reduces the capacity of every street thereby making them more prone to jams and the A1 near Salzburg is already heavily congested during rush hours.

This phenomenon is also explained here, how speed differences can cause phantom traffic jams even though capacity is nowhere near the limit of the road

But you will always have differences in speed, even if the limit is set to 90 for example, some will go at 100-110 and others at 80km/h...

The only way a such mesure could be effective will be when automatic cars will be all over roads...

You'd have to break the law for speed difference though, as literally nobody is going slower than 80 and those who do should not be having a license in the first place.

Is there a map with speed limits on different stretches of Austrian motorways?

I'm buying a car with cruise control solely because of that exasperating never-ending 80 speed limit through Vienna.

Now that Hungarian M85 slowly takes shape, are there any Austrian reactions on constructing the last 5 kms of A3 to the border? Shouldnt be too much to do imho, probably they even could just widen and grade-separate B16 there.

2nd May:

http://kurier.at/chronik/burgenland/...de/196.430.626
(german)

Asfinag is ready to react and will build it and not create a bottleneck

the same topic it will be on the Czech side with the S10 and A5, Asfinag build the important parts for Austria and wait with the rest for Czech is coming to the border with the R3 and R52

Why are Austria and the Czech Republic so poorly connected? You don't care about each other?

I would say that in 1990 the current Czech Republic was the most developed part of former comunist block. The motorways' network was quite well developed especially if you compare this with Poland, Slovakia and Hungary. What is striking is the inability of Czech governments in power after 1990 to finish quickly the motorway network.

The Hungarian motorway network wasn't so bad if you lived in Budapest. Not long, but in 4 directions.

Well economically the GDR people liked to buy things in Czechoslowakia, which were impossible to get at home. I tell people to be thankful, because as much went wrong, still the west gave billions to the east. The other communist states needed to come up alone. But i don't know why they evolved so different. If somebody has hints...?

Yes, a good observation. CZ has built comparatively few new motorways over the past 10 years. PL is going full speed ahead and SK is not too bad as well with their mountainous motorway stretches.

The Czech motorway plan will take forever to complete at the current pace. What is the preferred route from Vienna to Prague, via Nord Autobahn to Brno and then D1? Or Hollabrunn - Znojmo - D1. E49 seems to be too far out of the way.

You regard 5 almost unconnected motorways the most developed network when there was one in East Germany which was far more advanced. You can't be serious, can you.
