INVISIBILITIES: Just because you can’t see them (or prefer not to) doesn’t mean they are not there.

In a city, as in life, we normally register only what we set out to look for. The anomalies, the absences, the troubling, somehow escape our attention. But when it comes to transport, everywhere the eye might wander there are valuable clues, both visible and invisible, for planners and policy makers. However, if we fail to use our eyes we miss out on valuable information. And as a result our cities do just that much less well.
