There is another website that I've been using that provides similar functionality in terms of the heatmap: http://close.city

What I like about this one is that it can show travel times from a specific address. What would be even more useful is if it could show mixed-mode transportation times.

Really puts into perspective how wildly varied cities in the US are in terms of density and development patterns. Compare New York [1] and Seattle [2]. Barely a single patch of gray in New York until you get to Long Island, while Seattle has big patches with no transit accessibility at all. And many of them are extremely wealthy areas. In New York, wealthier areas tend to have better transit. Very, very interesting.

Goes to show the benefit of a well connected subway network. Seattle is mostly just buses except for two independent light rail lines
