The original Walkscore came out in 2007:
Three Seattle uber-hackers, Jesse Kocher, Matt Lerner, and Mike Mathieu, built this addicting new website. It maps the closest grocery store, restaurant, and several other businesses you might walk to from any address in the United States or Canada. It also gives each location a “Walk Score.” (You can even watch the site tally up the score. It’s awesome!)
But one little problem: you were often presumed to be a crow. Distances were calculated as though you could fly there in a straight line, or even walk on water.
Good news:
We’ve been hard at work creating a preview of Street Smart Walk Score—an enhanced version of Walk Score that uses walking distances rather than crow-flies distances to calculate your score.
Street Smart Walk Score also looks at the underlying road network to compute the number of intersections per square mile and average block length. These two measures are great indicators of walkability.
Preview Street Smart Walk Score.
Local angle:
We developed Street Smart Walk Score in conjunction with the Walk Score Advisory Board and Dr. Larry Frank, Professor of Sustainable Transportation at the University of British Columbia, and with funding from Active Living Research, a national program office of the Robert Wood Johnson Foundation.
This is a very welcome update! Thanks for the tip!
