This is a long post, but if you stick with it, you’ll be rewarded with what I think are some interesting maps at the bottom.
I’m currently working on a “streetscape master plan” project at work, with a focus on economic development for a 3.5 mile long major arterial roadway. I needed a way to measure economic activity, so I looked at walkscore.com. Walk Score looks at the walking distances from a defined location to the nearest grocery store, bars and restaurants, shopping, coffee shops, book store, bank, park, and school. The destinations are weighted by importance (see methodology here) and a walk score is generated. There are destinations included that aren’t related to economic activity, like the nearest park and school. However, the focus is largely on nearby businesses, so I thought it was an acceptable measure of economic activity. Here is the Walk Score map for Columbus:

Many of the green spots on the map are locations with major shopping centers (e.g., Graceland, Tuttle Crossing, Crosswoods, Polaris, Easton) and some are big box retail centers (e.g., Sawmill & SR-161, Hamilton & Morse, Stringtown Rd in Grove City). These types of economic activity centers tend to attract people from farther away, traveling by car. These aren’t really what I’m interested in measuring here. I’m interested in the walkable urban business districts that are mostly supported by the people within walking distance. This includes High Street from German Village through South Clintonville. The green spots appear to extend west into the Brewery District (Front Street) and east to German Village (3rd Street). Almost the entire downtown area is green. The segment of 5th Avenue in 5th by Northwest (north of Grandview Heights) is green. Grandview Avenue would be too if it were on WalkScore’s map. Main Street in Bexley is green. So is State Street in Uptown Westerville. These are some of Columbus’ great streets. They are the places with the most people on the sidewalks, the most shops and restaurants, the least vacancies, probably the biggest parking problems too. They’re the places you go for fun and where you take out-of-town guests to show them the best Columbus has to offer.
