Commuters could be tracked using their mobile phones under plans to tackle
overcrowding and increase revenue from advertising.

Fascinating selection of routes, some of which could be accounted for
by friends/relatives travelling together with different destinations
but on the same general route.

But why do people let the world know where they are? Not using the
device is not enough, It has to be switched off to avoid tracking.
Mine is only switched on when I am willing to accept calls or need to
make a call. That only amounts to a small proportion of my waking
hours so it is more often off than on..

Then you are in a small minority, and not part of the target market
for the applications in question.

Very small, going by my observations almost anywhere. There are some
reasons for my reluctance to be tracked, for any purpose, but this is
not the place to discuss them.
