| 説明 | This is even noisier than the block circumferences, probably because it is harder to say whether a point counts as being on a street than it is to say whether it is within a block, and because offset intersections can cause street segments that are smaller than real blocks. Spikes for particular block sizes are also especially evident, notably the 260-foot intersection spacing on north-south New York streets and the 900-foot spacing on South of Market San Francisco streets, a block length that is long enough to work poorly just about anywhere else. The green line is the 999th permillile of all blocks of a given length.Even with the noise and the spikes, though, there is enough of a curve to suggest that maximum popularity is found on blocks with intersection spacing of perhaps 300 feet. (This is a centerline to centerline distance, not curb to curb or building to building.)Geotags from Flickr, Twitter, and Picasa. Street segments from Census 2010 TIGER "edges" shapefiles. |
