Yellow / Beige Areas in Google Maps

In Google Maps, there are some areas which are coloured yellow (or, I'm told more accurately, beige). These apparently represent areas with high foot traffic. So when exploring a new city, they can be used to understand which bits people often walk around and which bits tend to be more residential / road traffic only. Really useful for working out which route to take through a city you're exploring.
