Took the train to Salzburg on the weekend to see a friend from Slovenia.

The historic centre of Salzburg is a pedestrian area controlled by bollards, but with some car access as you can see.

From what I can find: disabled people with a Euro-key can park inside, taxis can enter anytime (saw quite a few) and the bollards are down for deliveries before 11am. I guess before 11am the risk of confused/lazy tourists driving in is considered lower.

It seemed like a good balance.
