Fulton writes, "Walkscore.com's developers are working on incorporated more sophisticated walkability indicators into their scores -- things like density of roadway network, width of streets, and road speed. These improvements could enhance Walkscore's value as a planning tool. But as Walkscore gets closer to a qualitative judgment about whether a particular location is "good" or "bad," will its value as an objective tool decline?"
