Formulating a New Metric for Walkability

As walkable urbanism emerges as a new paradigm in real estate development, and studies demonstrate the value of walkable places to economic and personal health, the marketplace for defining and rating places friendly to pedestrians is rapidly expanding. Ben Schiller profiles Walkonomics, a new site that aims to provide a new tool for measuring walkability by aiming to build "as comprehensive a picture as possible."

"Services such as Walk Score
already score proximity to restaurants and shops (and more); how long
your commute is; and allow you to compare areas. But, according to Adam
Davies [founder of the site], that's only part of the story of walkability. Ideally, you also
want to know things like how safe the streets are, whether the sidewalks
are wide enough, how clear the signage is, and also--less tangibly--how
clean the street is, and whether it's relaxing and fun. Distance, in
other words, is not the only factor--perhaps not even the most important
factor."

"Currently covering about 600,000 streets in the U.K. and U.S., the site
is based on a mixture of government-sourced open data, and crowd-sourced
information from users. Streets are scored across eight categories,
based on data like traffic activity and crime statistics. Users can then
give their own impressions, shifting the scores over time."
