An evaluation of the trial, published today, shows that passengers
used 18
routes to go between King’s Cross/St Pancras and Waterloo, the busiest
stations on the network, with 40 per cent of people who were tracked
failing to take the two fastest routes. The data showed that even
within
stations a third of passengers did not use the quickest routes between
platforms and could be wasting up to two minutes.


I'm still trying to work out 18 different ways to travel between the two
by tube.

The Gizmodo article (which is far more detailed than the newspaper
reports) includes a diagram.

And it's not actually 18 different ways. It's 17 different ways that,
individually, have at least 0.1% of the journey traffic, plus
"others".

Does not Oyster and Contactless help to determine passenger routes and
flows? Isn't that the reason why TfL introduced it?


As the article points out, it doesn't track you through the system, just
the in and out points. The wifi data can follow you from platform to
platform.

Where the WiFi is operative. It quite clearly isn't at e.g. some
Jubilee Line stations or sections thereof.
