Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

You can correlate the times of trips there and back? Say, if I take my morning commute half an hour earlier you expect me to take my return trip also half an hour earlier, or something? Or maybe an hour later because I work longer on some weekdays than others?

Note the reference to anonymity.

It is the ability of the card to track real time movements of people collectively - ie the flows past the readers and therefore cardholders' presence shortly after on platforms - which is useful, I think.

I have noticed on the Tube that trains often seem to terminate early (to shuttle back), and re-route on an ad hoc basis - eg at an intersection like Camden Town on the Northern Line - far more than they used to.

I suspect that sophisticated analysis of people flows from Oyster data may be driving this traffic management.

A Diary from Bruce McF or DoDo on this might be interesting.

But you could have done that with the old electronic cards. Your other message about telphone switches makes me wonder whether the problem was more mundane - maybe the old electronic system involved thousands of lines of undocumented code in some obscure dialect of PL/I or COBOL, which you didn't get close to unless it was absolutely neccessary. So the data was there in the old system, but unusable.

It wouldnt be that much of a problem if it was Written in COBOL, it's a very straightforward language. it has a very undeserved reputation for complexity.

Yes, but they've probably pushed anybody who knows it into early retirement long ago...

Plenty of practicing Cobol and Fortran experts in Russia though...
