From that post:

The average bike score given by the Walkscore.com was 48 out of 100, putting Savannah at 77 out of the 122 cities rated. The only other Georgia city on the list was Atlanta, which received a score of 42. […]

I usually have a pretty stress free trip when I go riding and was a little surprised with Savannahâ€s low ranking, but I live relatively close to the Historic District, where most of the biking infrastructure is located.

I missed the Walkscore rankings of bicycle friendliness when they were released a couple of weeks ago, but you can see the Bike Score rankings here. The top ten cities are Cambridge, Mass.; Davis, Calif.; Berkeley, Calif.; Boulder, Colo.; Santa Monica, Calif.; Minneapolis, Minn.; Fort Collins, Colo.; Iowa City, Iowa; Hoboken, N.J.; and Ann Arbor, Mich.

Walk Score’s methodology for its new Bike Score is based on four equally weighted components:
Bike lanes
Hills
Destinations and road connectivity
Bike commuting mode share

Savannah’s ranking put us at the upper range of cities with “minimal bike infrastructure” and just two points shy of the range with “some bike infrastructure.”

But my street at the northern end of Thomas Square has a Walk Score of 80 (very walkable) and an even higher Bike Score: 89. “Flat as a pancake, excellent lanes.” I guess that refers to the bike lanes on Price and Lincoln, but I rarely use the Price Street lane and the Lincoln Street one leaves much to be desired. But given the width of streets in the neighborhood and the general lack of traffic — and the beauty and ease of accessing downtown proper — I’d definitely agree that the neighborhood is both very bikeable and very walkable. I actually haven’t even used my van for anything for the last four days.

In previous uses of Walk Score, I’ve been fairly impressed with how the statisticians are able to quantify neighborhood and community assets, so I do think these are meaningful numbers.

Some of the detailed listings of nearby businesses are incorrect, but the gist is right.

As Eric notes in his blog post, there are various plans for improving biking and walkability, some of which city officials don’t want to share specifics about right now. Why not?

Eric also notes the bungled plans to add pedestrian and bicycle corridors along Skidaway Road. Mystifyingly, county officials began by focusing on a more southerly portion of that stretch, where neighborhood opposition was strongest and where the use of the paths would have likely been minimal. They should have put the first emphasis on the stretch of Skidaway from Victory Drive to Savannah State University — an area that would be perfect for a dramatic upgrade in bikeability and walkability.

From Whatâ€s Your Walk Score?; The company that puts a number on walkability:

Walk Score is a website that takes a physical address—enter yours here—and computes, using proprietary algorithms and various data streams, a measure of its walkability. More recently itâ€s started tracking how transit-friendly neighborhoods are too. What drives the score is choice and proximity—the more amenities (restaurants, movie theaters, schools) you have around you, and the closer they are, the higher your Walk Score.

As Vanderbilt discusses (while punctuating his piece with myriad examples), Walk Score makes assumptions about walkability based on its algorithms that might not actually be borne out by experience.

Still, I’d argue that it’s a useful number in terms of planning and neighborhood analysis.

My block of Thomas Square has a Walk Score of 83

BUT but but . . . the list of bars near me does not include the one that I visit the most, and is closest to me: the lounge at American Legion Post #135. And the bar next door at Local 11 ten (one downstairs and Perch upstairs) aren’t listed. The Sentient Bean has regularly entertainment but isn’t listed under those amenities. Bull Street Eatery and Cafe Florie aren’t listed, but they’re closer than most of the restaurants on the list.

My parents live on the south side of the river, so they only have a Walk Score of 77 (still "very walkable")

My parents moved a number of years ago into downtown Frankfort, Kentucky from the rural area where they previously lived. My mother walks around downtown almost daily, but neither of them walks often to services. They live a tenth of a mile from a small grocery, but they routinely do their serious grocery shopping at a Kroger in the suburbs. Still, it’s clearly a walkable neighborhood — and it clearly has very easy car trips if residents are not willing or able to walk.

Out here at Armstrong where I teach, the Walk Score is 62 (“somewhat walkable”) but it’s hardly walkable given the way that Abercorn Street is designed. That’s something that the campus should address.

Savannah as a whole has a Walk Score of 47, far lower than even Armstrong’s.

Here’s what that looks like on the map — with the higher numbers in green.

Savannah's average Walk Score is 47

Ironically, with an average Walk Score of 53, Atlanta does better by these metrics than Savannah. That’s because many neighborhoods in the urban core are rated as highly walkable, even as the city has become widely known for its sprawl and car-dependency.
