" High Speed Turnoffs"

[shon7]

I have heard the argument that at some of the more modern airports the runways and taxi-ways have been developed in a way that they allow "high speed turnoffs." Two airports most often quoted in this regard are Atlanta and Zurich.

However, reading the max. taxi speed on a 747 thread - a "high speed turnoff" seems to be contradictory?

So I have two question;

1. Is there such a thing as a "high speed turnoff"

2. If there is how is this accomplished and under what circumstances.
